This is a decent guide. However, I have some things to add and to ask. Enhanced Sync and Fast Sync are in fact VSync as well, as in - they prevent visible tearing by not letting the front buffer (containing the current image) change, when monitor is displaying an image already. The difference is that typical VSync uses first-in-first-out queue for frame buffers, and Enhanced Sync uses last-in-first-out. That means that the frames that didn't meet the timing between refreshes get discarded instead of waiting in line to be shown, and that's why it doesn't limit FPS, and why input latency can be lower than VSync with triple buffering, as Enhanced Sync is equivalent to OpenGL's type of triple buffering. Anti-Lag works exaclty like you said, but you're still left with at least one frame of input lag. And to reduce input lag there, you have to use smart frame rate limiting - which means your FPS should never be limited by maxed out GPU. So not letting GPU max out in the first place is always better than fixing it with Anti-Lag. The popular recommendations like -3 and -4 FPS below refresh rate can be misleading because of diminishing returns. You're talking flat numbers, but frame times relative to FPS change exponentially. Say, difference between 116 FPS and 120 FPS is 0.28ms, while difference between 236 FPS and 240 FPS is 0.07ms - it's 4 times easier to miss the frame time VRR window then! And what matters to keeping VRR enanged at all times is not FPS, but frame times, so each single frame manages to get into the time window. So ideally, one should always take into account the refresh rate as well. A really good formula, used by Special K, is refresh-(refresh*refresh/3600), so, say for 240Hz screen a good number to limit at will be 224. You said you tried RTSS extensively, but you didn't mention what specific limiting you've tried. RTSS has front edge sync (prioritizes frame time stability), back edge sync (prioritizes input latency), and async (a balanced mode, leaning towards back edge sync). Secondly, disabling passive waiting significantly increases the precision of RTSS limiters. And last, but not least - never let FPS limiters fight over a game; ideally use one limiter or another, but two at the same time can lead to all sorts of issues. Since you mentioned FSR - you can also change DLSS/XeSS/FSR 3 to FSR 4 via OptiScaler. And for people on cards without FSR 4 support - XeSS is the next best thing, definitely better than FSR 3. Have you tried Special K? They say, its FPS limiter is unbeatable, ie. not that long ago, Digital Foundry said that SK's limiter was the only one being able to properly pace in Lossless Scaling FrameGen scenario. Plus, SK has AutoVRR mode, that configures things automatically for VRR users, including calculation of optimal FPS limit via the formula I mentioned earlier. And for non-VRR users like myself, it's got Latent Sync - it removes tearing without VSync's input latency, while also properly pacing frames, and allows reducing latency even further. I use it in Touhou (simple game, has to be locked to 60 FPS because game speed is tied to FPS) to get the same input latency as with 1000 FPS. Additional info on in-game vs external limiters. Modern games run input/simulation on a separate thread, while any external limiter can only alter the rendering thread. This is why, when the in-game limiter is made well, it can reduce latency further than any external limiter. But, as you said yourself, in-game ones tend to suck in more ways than one. The weirdest thing about them is when they limit to wrong FPS. Imagine me trying to enjoy AC: Odyssey on RX 480 with decent graphics - had to limit to 30 FPS, but ingame limiter limited to 31 instead, and external limiters had much more input latency. Had to OC my monitor to 62Hz for that single game shm. More on reddit.com

Here are some of the most useful (in my opinion) features; Frame-Rate Target Control (FRTC) This can be used to globally cap your framerate, good for preventing tearing and reducing power. Set this to 1fps lower than your FreeSync range for the best experience. Radeon Anti-Lag: This reduces latency dramatically and contrary to some folks beliefs, and unlike Nvidia Reflex, Anti-Lag works with all titles. Fantastic setting to keep enabled globally. Also, Anti-Lag+ is coming soon which improves upon this feature. Radeon Chill: This allows you to set a minimum & maximum framerate either globally, or on a per-game basis and is incredibly useful as a way to reduce power draw and temperatures. I find it works best in slower paced titles, such as BG3. If you don't touch your mouse or keyboard, it only runs the game at the minimum FPS specified. The moment you touch something, performance goes right back up to whatever you set as your maximum framerate. Enhanced Sync: This is a generally superior V-Sync alternative that also reduces input lag rather than increasing it, like traditional V-Sync tends to. A great way to prevent tearing or just increase how smooth/responsive a game feels. Works with FreeSync and Anti-Lag, too. Radeon Boost: This works by using DRS to scale a games resolution to what you prefer (50%, 66%, 83%) - similar to Chill, it responds to your input. When you're moving your mouse around a lot and there's more demand on the GPU, it dynamically drops the resolution to maintain higher framerates. When the opposite is happening, it scales your resolution back up. Radeon Image Sharpening: This is one of the best features and something I highly recommend everybody try. This uses Contrast Adaptive Sharpening (RCAS) to sharpen the areas of the game that are more blurry, and doesn't sharpen (or not as much) areas that don't require it. It works on a global or per-game basis, but I prefer keeping a global setting of 10%. So there's an admittedly somewhat long list of what, in my opinion, are the best features RSX has to offer. But there's much more, so take a look around. Radeon ReLive is fantastic. The advisors tab is great to see frametime graphs and performance in games. List goes on. One last thing I want to mention, is go to the "Gaming" tab and under "Graphics" scroll down, click "Advanced Settings" and set Texture Filtering Quality to "High" -- this costs nothing and improves the quality of anisotropic filtering. Hope this was helpful! More on reddit.com

Ris on everything else off and just use frs in game for scaling, if a game doesn’t support frs and you need to scale to get a decent frame rate then you can set rsr for that specific game More on reddit.com
