The videos show how Anti-Lag reduces latency and how FSR boosts frame rates with demanding detail settings.<!--more--><\/p>\n<h3><strong>AMD FidelityFX Super Resolution (FSR)<\/strong><\/h3>\n<p>The first generation of FSR is an algorithm that uses compute shaders to upscale images with higher quality than what traditional image interpolation methods could achieve.<\/p>\n<p>If your GPU previously couldn\u2019t handle a game at your desired detail level, one option was to lower the render resolution and interpolate the lower-resolution image up to the monitor\u2019s native resolution.<\/p>\n<p>FSR 1 works on a similar principle, but compared to basic and fast interpolation methods of lower quality (usually bilinear or bicubic interpolation), the resulting image is sharper and more detailed.<\/p>\n<p>This is a software solution that utilizes the compute shaders of the graphics chip for interpolation. It\u2019s not tied to any specialized processing units and works on all modern GPUs regardless of manufacturer.<\/p>\n<p>One major drawback is that it processes only the current frame. As a result, it can\u2019t make use of data from previous frames to improve image quality and struggles to maintain visual consistency between frames.<\/p>\n<h3>AMD Radeon Super Resolution (RSR)<\/h3>\n<p>Radeon Super Resolution (RSR) is AMD\u2019s technology for enhancing performance and upscaling quality in games, even if they don\u2019t natively support FSR. It builds on the principles of the first-generation AMD FidelityFX Super Resolution (FSR), but with one key difference \u2013 RSR is integrated directly into the Radeon GPU drivers and functions system-wide, not just in games with native FSR support.<\/p>\n<p>Compared to in-game FSR, RSR has some limitations. It doesn\u2019t work in windowed or borderless windowed modes.<\/p>\n<p>The image may not be as clean or sharp as with native FSR, because FSR can render interface elements like HUD in full resolution, while RSR upscales the entire rendered image from a lower resolution.<\/p>\n<p>This feature is only available on AMD Radeon RX 5000 series graphics cards and newer.<\/p>\n<h3><strong>AMD FidelityFX Super Resolution 2<\/strong><\/h3>\n<p>The second generation of FSR introduced a more advanced upscaling method that uses temporal upscaling. This allows the algorithm to combine information from multiple frames, increasing the number of samples and producing a more detailed image.<\/p>\n<p>Unlike the first generation, it doesn\u2019t rely solely on the current frame, but can also utilize data from previously rendered frames, motion vectors, and scene depth maps. This enables it to recreate finer details, reduce flickering of elements between frames, and improve stability. However, it can still produce edge artifacts on moving objects, as there isn\u2019t enough sample data in areas where those objects overlapped in previous frames.<\/p>\n<p>It remains a software-based solution using compute shaders, and doesn\u2019t require specialized processing hardware. As such, FSR 2 runs not only on AMD GPUs, but also on modern graphics chips from Nvidia and Intel.<\/p>\n<p>The result is noticeably better image quality than FSR 1, especially at lower internal resolutions.<\/p>\n<h3><strong>AMD FidelityFX Super Resolution 3<\/strong><\/h3>\n<p>The third generation builds on FSR 2 and brings two key innovations \u2013 enhanced temporal upscaling and frame generation, which increases framerate beyond what the game engine can natively produce.<\/p>\n<p>FSR 3 improves upscaling regardless of whether frame generation is enabled. Compared to FSR 2, it delivers a more stable image, reduces flickering of fine details, preserves small structures better, and lowers the occurrence of artifacts during fast motion. Improvements also include better handling of motion vectors and depth information.<\/p>\n<p>Its standout feature is frame generation, which calculates and inserts artificial frames between rendered ones. This significantly boosts perceived smoothness, particularly in demanding titles or at high resolutions.<\/p>\n<p>However, for frame generation to be effective, the base framerate must already be relatively high \u2013 typically around 60 fps. At lower performance levels, the quality of generated frames drops, and artifacts become more noticeable. It\u2019s best suited for playing demanding games on high refresh rate monitors.<\/p>\n<p>A drawback is a slight increase in latency due to the need to delay the last rendered frame.<\/p>\n<p>Another new feature is official support for <strong>Native AA<\/strong>. In this mode, the game runs at the display\u2019s native resolution with full detail, while the temporal algorithm from FSR is used to enhance anti-aliasing quality.<\/p>\n<p>Like previous versions, FSR 3 is a software solution using compute shaders. It\u2019s not tied to specialized hardware, but its support depends on the game and GPU drivers. The technology works on AMD, Nvidia, and Intel GPUs that meet the requirements.<\/p>\n<h3><strong>AMD FidelityFX Super Resolution 4<\/strong><\/h3>\n<p>FSR 4 is the next generation of AMD\u2019s image upscaling algorithm.

This would be even clearer in comparison videos, but that\u2019s probably better left for a separate article.<\/p>\n<p>On new Radeon cards, you can get FSR 4 working in most games by enabling it in AMD Software and selecting FSR 3.1 mode in the game. The drivers will then automatically replace the older version with the latest FSR 4 in supported titles.<\/p>\n<p>With FSR 4, even demanding games can be played at very high graphics settings in 4K resolution on a more affordable Radeon RX 9060 XT, without frame generation. While native resolution delivered an average framerate of around 48 fps in the benchmark \u2013 which is well below the refresh rate even for cheaper 60Hz monitors and not very pleasant for gaming (partly due to higher input lag) \u2013 with FSR 4, you can reach an average of over 66 fps while maintaining good image quality.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/horizon-fsr4.png\" alt=\"\" width=\"779\" height=\"513\" \/><\/p>\n<p>The following examples show a comparison from the Horizon Zero Dawn benchmark, set to Very High at 2560 \u00d7 1440 resolution, with FSR in Balanced mode.<\/p>\n<p>Below are cropped screenshots that you should see at 1:1 resolution on a PC with standard DPI settings.

It reduces the delay between a mouse movement or keypress and the reaction on screen by dynamically adjusting frame timing. Its biggest benefit is in situations where game performance is GPU-bound.<\/p>\n<p>The first generation of Anti-Lag is supported from Radeon RX 400 series and newer, as well as Ryzen 200 and newer APUs, and works with DX9, DX11, and DX12 APIs. This is the older generation of the technology.<\/p>\n<p>AMD later introduced an improved variant called Anti-Lag+, followed by Anti-Lag 2.<\/p>\n<p data-start=\"0\" data-end=\"243\"><strong>Anti-Lag 2<\/strong> builds on the original driver-based Anti-Lag technology, but is integrated directly into the game itself. It intervenes in the graphics pipeline at an ideal point \u2013 just before the game begins processing inputs from the mouse, keyboard, or gamepad.<\/p>\n<p data-start=\"245\" data-end=\"419\">This allows for better synchronization not only between the CPU and GPU, but also throughout the internal game loop. As a result, it&#8217;s possible to reduce latency more significantly than with driver-level interventions.<\/p>\n<p data-start=\"421\" data-end=\"634\" data-is-last-node=\"\" data-is-only-node=\"\">Naturally, for Anti-Lag 2 to work properly, developers need to integrate the technology directly into the game code using the available SDK. Ideally, they can also give players the option to enable or disable Anti-Lag 2 in the game settings. However, integrating it becomes more complicated when combined with Frame Generation, and in some games, you might run into issues such as stuttering when both technologies are active at the same time.<\/p>\n<h3>Radeon Anti-Lag \u2013 Global Settings<\/h3>\n<p>You can enable Anti-Lag globally for all supported games, or configure it individually for specific titles using application profiles in <strong>AMD Software: Adrenalin Edition<\/strong>.<\/p>\n<p>In AMD Software, click the magnifying glass icon in the top right corner and enter \u201canti-lag\u201d into the search field, or navigate manually via the Gaming section &gt; Graphics &gt; Radeon Anti-Lag.<\/p>\n<p><a href=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-global-settings-en.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-250520 size-large\" src=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-global-settings-en-1024x1020.jpg\" alt=\"\" width=\"640\" height=\"638\" srcset=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-global-settings-en-1024x1020.jpg 1024w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-global-settings-en-300x300.jpg 300w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-global-settings-en-768x765.jpg 768w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-global-settings-en.jpg 1279w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<h3>How to Configure Anti-Lag for Specific Games:<\/h3>\n<p>From the main menu of AMD Software, go to the Gaming section, select the Games tab, and choose the profile of the game where you want to configure Anti-Lag.<\/p>\n<p>The local setting for that specific game will override the global setting.<\/p>\n<p><a href=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-game-profile-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-250521\" src=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-game-profile-1-1024x919.jpg\" alt=\"\" width=\"640\" height=\"574\" srcset=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-game-profile-1-1024x919.jpg 1024w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-game-profile-1-300x269.jpg 300w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-game-profile-1-768x689.jpg 768w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/amd-game-profile-1.jpg 1278w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<h2>Anti-Lag 2<\/h2>\n<p>Anti-Lag 2 should already be integrated directly into supported games.

The videos show how Anti-Lag reduces latency and how FSR boosts frame rates with demanding detail settings.<!--more--><\/p>\n<p>To measure latency on Radeon GPUs, you can try using the <strong>AMD Frame Latency Meter<\/strong>, which we <a href=\"https:\/\/www.hwcooling.net\/amd-frame-latency-meter-uvod-do-mereni-latenci\/\">introduced shortly after its release<\/a>.<\/p>\n<p>For a quick demonstration, we\u2019ll test two games. To showcase the classic driver-enforced Anti-Lag, we\u2019ll use Cyberpunk 2077, which \u2014 at least at the time of testing \u2014 didn\u2019t yet have Anti-Lag 2 integrated. The game is also known for noticeable input latency.<\/p>\n<p>You can see the practical difference in the slow-motion footage. The video was recorded with a Sony RX10 II mirrorless camera at 1000 frames per second and slowed down to 25 fps. The image quality isn\u2019t great, as extremely short shutter speeds were required, which in turn meant using high sensitivity settings.<\/p>\n<p>This time, we\u2019re sticking to just one configuration and two games, as the measurement was done manually \u2013 by recording footage and counting frames. Although this is laborious and time-consuming, unlike software-based methods or tools like OSRTT, it provides a very accurate picture of how the monitor and Anti-Lag actually behave in real time \u2013 and whether any issues occur in the entire input-to-display chain.<\/p>\n<p>This is as close to real-life testing as it gets \u2013 we use a mouse mounted on a robotic arm driven by a stepper motor, and then measure how long it takes for mouse movement to appear on the screen. In the video, an LED indicates the moment the motor takes its first step. At that point, the mouse itself hasn\u2019t moved yet \u2014 it takes a few microsteps for the motor to get going, and the mouse movement becomes visible after 3 to 4 milliseconds. From that moment, we count how many frames \u2014 and therefore milliseconds \u2014 it takes for the cursor movement to appear on the screen.<\/p>\n<p>One major advantage in this test is access to an extremely fast QD-OLED panel. Traditional LCDs require several milliseconds to realign liquid crystals properly, and even after a single screen refresh, residual ghosting can remain. Achieving the correct shade often requires two or three redraws. In contrast, OLED displays can switch pixels on and off in just fractions of a millisecond.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/mouse-slider.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/mouse-slider.jpg\" alt=\"\" width=\"780\" height=\"432\" \/><\/a><\/p>\n<p>The extreme redraw speed that OLED displays offer compared to conventional LCDs plays a key role in our Anti-Lag testing \u2014 and you can clearly see the difference in the slow-motion footage. While a typical 60Hz monitor refreshes once every 16.66 ms, a 360Hz OLED panel can refresh every 2.77 ms. On slower panels, player input response can be delayed by up to 16.7 ms purely due to refresh intervals, but on the OLED panel used here, the refresh delay never exceeds 3 ms. On the other hand, Anti-Lag technology, which helps improve frame timing, can be even more beneficial on slower monitors.<\/p>\n<h2>Cyberpunk 2077 and Anti-Lag<\/h2>\n<p>Cyberpunk 2077 features a large open world and complex, performance-intensive graphics. This also affects the game\u2019s responsiveness, which tends to be worse than in most other titles. At lower framerates, screen feedback noticeably lags behind mouse movements. It\u2019s one of those games where Anti-Lag significantly improves playability \u2013 especially on weaker graphics cards.<\/p>\n<p>Total system latency is the sum of delays from various components, starting at the mouse and ending with the monitor. As such, measured values can vary widely, and a few tests are not enough. The pair of graphs below shows 32 measurements comparing latency with Anti-Lag enabled and disabled in AMD Software.<\/p>\n<p>Average response time without Anti-Lag is 73.9 ms. When enabled, that drops to 47.3 ms on average.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/cyberpunk-antilag-off.png\" alt=\"\" width=\"780\" height=\"244\" \/><\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2025\/06\/cyberpunk-antilag-on.png\" alt=\"\" width=\"780\" height=\"244\" \/><\/p>\n<p>The slow-motion video below shows two representative recordings chosen to reflect the average latency observed in testing.<\/p>\n<p style=\"text-align: center;\"><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/jtp6PlAFYrg?si=bWZr8MZYZkROG1ms\" width=\"780\" height=\"438\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script>\n<!-- responsive -->\n<ins class=\"adsbygoogle\"\n     style=\"display:block;background-color:transparent\"\n     data-ad-client=\"ca-pub-8150419924824893\"\n     data-ad-slot=\"6522017574\"\n     data-ad-format=\"auto\"><\/ins>\n<script>\n(adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><br \/>\n\u2800<\/p>\n<p><!--nextpage-->The new AMD Radeon RX 9000 cards with RDNA4 architecture bring higher performance and a suite of technologies to make gaming more enjoyable and improve responsiveness.
