If you've just bought a powerful Radeon graphics card, like a 9000 XT series, you've probably noticed that the panel of AMD Adrenaline It's full of options They sound great, but it's not always clear how to use them. Anti-Lag, Enhanced Sync, driver-level FSR, Radeon Boost, HYPR-RX… all of these can make the difference between an experience full of micro-stuttering and tearing or a smooth gaming session with good frametimes and very low input lag.
The aim of this guide is to help you Get the most out of your GPU with AMD Adrenalin to gain FPS and stability, maintaining decent image quality and preventing the settings from becoming a mess. You'll see how to combine driver options with those of the game itself, when to limit FPS, what to do with FreeSync, VSync, and Enhanced Sync, and how to use tools like Performance Tuning without resorting to crazy overclocks if you don't want to.
Understanding the objective: FPS, frametimes, and input lag
Before adjusting settings, it's important to understand that we're not just looking for more FPS "by brute force," but a balance between frame rate, stability, and controller or mouse responsivenessIn other words: no micro-stutters, no weird jerks, and no annoying lag when moving the camera.
When we talk about real smoothness, we are interested in both the average FPS and the frametimes, which are the milliseconds it takes for each frame to be displayedIf the frametimes are very irregular, even if you have 120 FPS, it will feel choppy. That's why, properly limit FPS Properly configuring FreeSync/VSync/Enhanced Sync is almost as important as setting the graphics to High or Ultra. Another key point is the input lag: the time between your action and what you see on screen.
Finally, it must be taken into account that Not all games behave the same. A competitive title like CS2 can reach hundreds of FPS, while a modern RPG with cutting-edge graphics (like Avowed or other recent titles) might struggle to reach 60 FPS in 4K with everything maxed out, even on very powerful hardware. That's why this guide provides a general framework that you can then adapt for each game.
AMD Adrenalin global settings to gain FPS
The first step is to properly configure the Adrenalin global profile. This way, All games will start from an optimized base. and you will only have to adjust individually those that cause problems or have specific needs.
In RDNA4 graphics cards, AMD has added the ability to Activate FSR 4 directly from the controllerThis means that any game compatible with FSR 3.1 will automatically take advantage of FSR 4 when the driver enables it, without you having to change anything in the game itself. AMD refines this integration with driver updates, so it's a good idea to keep your drivers up to date.
In addition to driver-level FSR, the global panel allows you to control options such as Anti-Lag, Enhanced Sync, FPS limiter and other filters. The idea is to have a configuration that works well "for almost everything," and if a game behaves strangely (crashes, flickering, strange stuttering), then disable specific functions until you find the culprit.
A key concept that we will see throughout is that of limit the FPS to a value very close to, but slightly lower than, the refresh rate from the monitor. This, combined with FreeSyncThis is usually the smoothest possible combination, as long as we don't force VSync to activate when we don't want to add latency.
FSR at the controller level and combination with the game's FSR
If your GPU is RDNA4 architecture, Adrenalin allows Force FSR 4 from the driver itself for games compatible with FSR 3.1In practice, this means that many titles that already have a recent FSR mode will be able to improve quality or performance without the game being updated, simply thanks to the driver.
This type of "global" FSR is designed so that You don't always have to depend on the developer implementing the latest version in each title.
When a game already includes FSR in its own menu, the ideal thing to do is usually First, use the game's native FSR and leave the driver as a backup.The reason is that the game may be optimized for that specific mode (interfaces, sharpness, scaled UI, etc.). But if you find that Adrenalin offers additional improvements or more stable performance, feel free to try the controller option and compare.
It is important to note that not all rendering modes work the same. If you play in borderless windowed mode or full screen windowed modeSome games limit or completely disable FSR or exclusive display modes. In those cases, driver-level help can make a difference, although it will depend on whether the game allows that integration.
AMD Anti-Lag, Enhanced Sync and tearing management
Among Adrenalin's key functions for enhancing the gaming experience, AMD Anti-Lag is one of the key playersIts function is to reduce input lag. That is, the "delay" you notice between moving the mouse or pressing a key and seeing the result on the screen. It's especially useful when the GPU is under 100% load. That's where it's most noticeable.
In most modern games, Anti-Lag works well and is an excellent option for achieving a smoother experience.This is especially true in competitive shooters or fast-paced action games. However, some titles may exhibit strange behavior with these latency technologies (graphical glitches, crashes, added stuttering), so if you notice anything unusual after enabling it, this is one of the first things you should disable.
On the other hand, Enhanced Sync is AMD's alternative to the classic VSyncIts goal is to reduce or eliminate screen tearing (those horizontal image "breaks") without adding as much latency as traditional VSync. It's similar to what Nvidia calls Fast Sync: it aims to maintain a cleaner image while preventing the game from feeling sluggish.
The downside is that Enhanced Sync, although it works very well in most cases, It's not always as effective at eliminating tearing as a full VSync..
AMD FPS limiter, FreeSync, and the -4 FPS rule
One of the most powerful, and often underrated, weapons on the Adrenalin panel is the controller-level frame rate limiterThis option allows you to set an FPS cap that will apply to all games (or per profile), regardless of whether the title includes an internal limiter or not.
The widespread recommendation, based on extensive evidence, is Limit the FPS to 4 below your monitor's refresh rateFor example, if your screen has a 120Hz refresh rate, set a limit of 116 FPS. If it's 240Hz, set it to 236 FPS. Why such a specific number? To keep the game's FPS within the FreeSync range without forcing VSync to activate or causing added latency.
When the FPS consistently exceeds the monitor's maximum refresh rate, The system tends to activate VSync or generate tearingFurthermore, very annoying frametime spikes occur. By maintaining that 4 FPS margin, adaptive sync (FreeSync) works within its optimal range and unnecessary stuttering is avoided.
If a game already has its own FPS limiter, the ideal approach is to follow this priority: First, use the game's internal limiter, and if it's not good or doesn't allow fine-tuning, use the AMD or RTSS limiter.There are games where the built-in limiter is very well programmed and offers better frametimes than an external limiter, but others only allow options like 30-60-100-120-200 FPS without letting you set, for example, 116 or 236. In those cases, it's best to disable it and use Adrenalin's more precise control.
Image sharpening, Radeon Boost, and visual quality
In addition to features focused on FPS and latency, Adrenalin includes sharpening filters and scaling techniques These settings help improve image clarity when using TAA or dynamic resolutions. A common trick is to use global or game-specific sharpening at around 70% in titles with strong TAA.
The reason is that TAA often over-softens the image, leaving it somewhat blurry.Especially at 1440p or 4K with upscaling. Adding a touch of sharpness (without overdoing it) helps recover detail without generating too many artifacts. A value around 70% is usually a good starting point, although you can adjust it according to your personal taste and the specific game.
Regarding Radeon Boost, it's a feature that dynamically reduces resolution during periods of high motion to gain performance, and returns it to its normal value when the camera is more stable. In practice, this translates to more FPS in chaotic scenes, with a relatively small visual impact if implemented well.
Not all players are comfortable with the idea that the resolution changes during the gameeven if only temporarily. If you're very sensitive to sharpness, you might prefer not to activate it in narrative games or titles where visual quality is paramount; however, in competitive shooters or fast-paced games, it can be a very useful tool for maintaining fluidity when the action heats up.
In any case, the most sensible thing to do is to test Radeon Boost in some specific titles and assess whether the FPS gain compensates for the possible temporary loss of fidelityThere is no universal rule; it depends a lot on the type of game and how demanding you are about the image.
HYPR-RX, profile modes, and fluid motion
HYPR-RX is a type of "All-in-one" mode within AMD Adrenalin. It combines several in-house technologies (such as Anti-Lag, Boost, FSR and specific optimizations) to offer more performance in a simple way, without the user having to manually adjust everything.
If you don't want to overthink things, Using HYPR-RX as a base profile can be a fairly convenient optionEven so, it's worth knowing what's being activated under the hood. Especially if you start noticing strange behavior in a particular game (for example, unusual screen tearing, stuttering, or text that appears too blurry).
Regarding the general experience modes (e.g., balanced versus performance), the key is finding the sweet spot where You gain FPS without the image looking outdated.For a 4K 240Hz monitor, always demanding the maximum FPS with everything on Ultra is unrealistic in recent AAA titles. Instead, a well-configured balanced mode can deliver 70-90 FPS with good quality. For many gamers, that's more than enough.
Some "smoothing" or "motion smoothing" features may give the impression that the game is running more smoothly, but They don't always mean more real FPS.These are more like adjustments for interpolation, synchronization, or frame management. Here, the recommendation is to always prioritize stable frametime and low input lag over smoothing effects that might add delay or artifacts.
In summary, HYPR-RX and the predefined profiles are a good starting point, but You'll get the best experience by manually fine-tuning the key settings: Anti-Lag, Enhanced Sync, FPS limiter, FSR and sharpness.
When to use the game's limiter, AMD's, or RTSS
The choice of FPS limiter greatly influences the perceived smoothness. There are three main options:
- Internal game limiter.
- AMD Adrenalin Limiter.
- External tools such as RivaTuner Statistics Server (RTH.H).
When the game includes a well-made limiter (with custom values ​​and good frametime control), It's usually the best option to use it first.Being integrated into the engine allows for better coordination of frame generation, rendering, and synchronization with the game's internal logic.
However, many games only allow Predefined FPS values ​​such as 30, 60, 100, 120 or 200without the option to set an exact number. On 120Hz or 240Hz monitors, this complicates applying the famous -4 FPS rule for FreeSync, so in those cases it's more advisable to disable the built-in limiter and use AMD's or RTSS to set, for example, 116 or 236 FPS.
RTSS, for its part, is a very popular third-party tool that It offers an extremely consistent FPS limiter and compatible with virtually all games. If you decide not to use Adrenalin's limiter or prefer independent control, RTSS is completely safe and usually delivers excellent results, provided you configure it correctly and leave it running in the background. View FPS.
If you choose RTSS, it's important Disable Enhanced Sync and force VSync in Adrenalin to avoid conflicts in rendering times. Otherwise, you could encounter frametime spikes and inconsistent latency despite having a seemingly perfect FPS limit.
What to do when a game is acting strangely
No matter how well you have configured your global profile, There will always be some games that don't work well with certain features. Driver issues: flickering, crashes, disappearing textures, unexpected stuttering, etc. In these cases, it's best to proceed methodically.
- As a first step, if a title starts behaving strangely after enabling optimizations, Disable AMD Anti-Lag and check if the problem disappears.This function, although useful, is one of those that most significantly affects frame management.
- If problems persist after disabling Anti-Lag, the next candidate is disable Enhanced Sync in that specific gameSome game engines handle synchronization in a peculiar way and don't work well with advanced sync modes. Again, it's best to adjust this in the game's individual profile to avoid breaking other games.
- If none of that works, you can try return to the most basic possible configuration. This means no Anti-Lag, no Enhanced Sync, no forced FSR from the driver, and with VSync and the limiter managed exclusively by the game. If the game runs smoothly this way, then reactivate Adrenalin's features one by one until you identify the one causing the conflict.
Remember that this guide proposes a very solid general configuration, but There will always be exceptions where manual adjustments are needed.That's part of the "charm" of PC gaming. Each title has its own personality and sometimes requires a bit of trial and error.
Performance Tuning, overclock and undervolt on AMD
The Performance Tuning section within Adrenalin is where AMD concentrates all overclocking, undervolting, and fan control optionsFrom there you can adjust the GPU frequencies, memory, voltages, and fan curves to tailor the card's behavior to your preferences.
For someone starting out in the world of PC gaming, it's normal to feel a sense of awe towards overclocking. Adrenalin makes these tasks much easier with its secure profiles and controls.But if you haven't done your research or don't feel like doing lengthy tests, you don't have to change anything to enjoy good performance.
A very interesting alternative is the Moderate undervolt: slightly lower the voltage while maintaining similar frequenciesThis typically reduces power consumption and temperature, which improves stability and can even better sustain GPU clock speeds during extended sessions, preventing overheating-related drops. Many modern Radeon graphics cards come with enough headroom to reduce voltage slightly without a noticeable performance loss.
Additionally, you can manually adjust the fan curve to to find a middle ground between noise and temperatureA GPU that stays cool tends to handle turbo clocks better. This can indirectly translate to slightly more stable FPS, especially in very demanding 4K titles.
In any case, if you still don't feel comfortable getting into Performance Tuning, that's okay: The biggest FPS gains come from a combination of graphics settings, FSR, sync, and FPS limiterTuning frequencies and voltages is the icing on the cake, not the main course.
Classic VSync, AMD version, and 240Hz monitors
With a 240Hz monitor, the temptation is Always aim for the highest possible FPS rateBut the reality is that only a few lightweight competitive games will be able to approach that figure at 4K resolution. That's why it's important to understand what each type of sync offers and how it performs on high refresh rate displays.
Classic VSync takes care of lock the frame rate to that of the monitorIt does this to prevent screen tearing, but in return, it adds latency, especially when the game's FPS doesn't match the refresh rate. This might be less noticeable at 240 Hz than at 60 Hz, but it's still there. And it can be quite noticeable in fast-paced shooters.
AMD's version, combining FreeSync and Enhanced Sync, It aims to reduce screen tearing without introducing too much latency.On a 240Hz screen with FreeSync enabled, a highly recommended configuration involves enabling FreeSync, using Enhanced Sync in the driver, disabling VSync in the game, and limiting the FPS slightly below the maximum to prevent the system from switching between synchronization states.
In practice, this means that AMD's synchronization version is usually preferable to traditional VSync For those who value fast mouse response and a sense of immediacy. There will always be specific cases where pure VSync is visually cleaner, but for most gamers and titles, Enhanced Sync + FreeSync + a properly configured limiter is the winning combination.
By understanding the correct combination of FSR, Anti-Lag, Enhanced Sync, FPS limiter, and, when appropriate, Performance Tuning, it is possible turn AMD Adrenalin into a powerful tool for gaining FPS and stability Without sacrificing a decent image, even in 4K. With a well-configured overall baseline and minor adjustments per game, you'll avoid microstutters, keep input lag under control, and enjoy your top-of-the-line Radeon with the feeling that it's truly performing at its best.
