You peek mid on Dust2. Your crosshair lands on the enemy head. You click. The shot registers late. The scoreboard shows 200 FPS but your mouse feels like it is dragging through mud.
This guide shows the best AMD settings for CS2 performance. You will learn driver configuration, Anti-Lag 2 setup, in-game video settings, and system tweaks that reduce input lag and stabilize frame times without sacrificing visibility.
AMD Radeon Optimization for Counter-Strike 2
Source 2 engine demands different optimization than CS:GO. Anti-Lag 2 synchronization, smart shadow management, and driver configuration matter more than blindly setting everything to low.
The Critical Setting: AMD Anti-Lag 2
CS2 uses a sub-tick server system that timestamps every mouse click at the exact millisecond it happens. Your GPU might be rendering 300 frames per second, but if those frames are queued up waiting to be displayed, your click registers late on the server.
Anti-Lag 2 is not a driver hack. Valve integrated it directly into the Source 2 engine using AMD’s SDK. It works exactly like NVIDIA Reflex by eliminating the render queue. The CPU only starts working on a new frame when the GPU is ready to receive it.
Result: The time between your mouse click and the bullet leaving your gun drops by 30 to 40 percent in GPU limited scenarios. This is the single most important setting for competitive CS2.

In-Game Video Settings Breakdown
System Level Optimizations
Smart Access Memory allows your CPU to access the entire GPU VRAM frame buffer at once instead of 256MB chunks. CS2 constantly streams high resolution textures and geometry data. SAM reduces CPU overhead for these transfers.
Requirements: Ryzen 3000/5000/7000/9000 CPU + Radeon RX 5000/6000/7000 GPU + compatible motherboard.
Steps:
- Restart PC and enter BIOS (usually Delete or F2 key)
- Find Settings or Advanced menu
- Enable “Above 4G Decoding”
- Enable “Re-Size BAR Support”
- Save and exit BIOS
Result: Benchmark tests show significant uplift in 1% low FPS (smoothness) even if average FPS changes minimally. This stabilizes frame times during texture streaming.
Windows 10 and 11 use a hybrid borderless mode called Fullscreen Optimizations that adds a composition layer for faster alt-tabbing and overlays. This interferes with exclusive GPU access to the display buffer and introduces variable input lag.
Steps:
- Navigate to your CS2 installation folder (usually Steam\steamapps\common\Counter-Strike Global Offensive)
- Find cs2.exe and right click > Properties
- Go to Compatibility tab
- Check “Disable fullscreen optimizations”
- Click Apply and OK
Result: Forces true legacy exclusive fullscreen mode. Benchmarks show improved 1% low FPS by ensuring consistent frame pacing without Windows DWM interference.
RDNA cards on Windows can suffer stutters when shader compilation happens mid-game. A registry modification forces more persistent shader caching to prevent these micro freezes.
Steps:
- Press Win+R and type “regedit” then Enter
- Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\UMD
- Find or create a value named “ShaderCache”
- Set data to “32” (Hexadecimal)
- Close registry editor
- Clear DirectX shader cache via Disk Cleanup
- Restart PC
Result: Forces shader cache ON state, preventing aggressive deletion of compiled shaders. Reduces first-time stutter when new visual effects appear.
Launch Options and Autoexec
In CS:GO, launch options were critical for optimization. Source 2 has a sophisticated built-in scheduler that makes most old commands obsolete or harmful. Use minimal launch options.
-threads X: Source 2 has sophisticated thread scheduler. Forcing thread counts conflicts with engine and causes micro stutters.
+cl_interp: Networking commands are locked in CS2 sub-tick system. Old CS:GO networking configs are obsolete and ignored.
Troubleshooting Common AMD Issues
Cause: Shader cache invalidation when new assets load.
Solution:
- Let game sit in main menu for 5-10 minutes
- Play Deathmatch with bots to force all effects to load
- Reset shader cache in AMD driver settings
- Stutters should subside after first full match
Cause: Unstable overclock or driver conflict.
Solution:
- Use DDU (Display Driver Uninstaller) in Safe Mode
- Install minimal version of latest WHQL driver
- Ensure RAM XMP profiles are stable
- CS2 is very sensitive to memory instability
Cause: Background applications or power settings.
Solution:
- Close Chrome, Discord, streaming apps
- Set Windows power plan to High Performance
- Disable Windows Game Mode and Game Bar
- Check GPU is not thermal throttling in AMD Software
Cause: V-Sync or frame buffering.
Solution:
- Ensure V-Sync is OFF in driver and game
- Enable Anti-Lag 2 in both driver and CS2
- Disable Radeon Chill and Radeon Boost
- Check “Disable fullscreen optimizations” on cs2.exe

FAQ
What is AMD Anti-Lag 2 and why is it important for CS2
Anti-Lag 2 is Valve’s integration of AMD technology directly into the Source 2 engine. It eliminates the render queue by synchronizing CPU and GPU frame pacing, ensuring your mouse clicks register on the server at the exact moment you press the button. This reduces input lag by 30 to 40 percent in GPU limited scenarios and is critical for CS2’s sub-tick system.
Should I use DirectX 11 or Vulkan for CS2 on AMD
Use DirectX 11. Community benchmarks on RDNA hardware show DX11 delivers higher average FPS, better 1% lows, lower input latency, and faster alt-tab recovery compared to Vulkan on Windows. Only switch to Vulkan if you experience crashes with DX11 or are playing on Linux.
What resolution should I use for best FPS on AMD GPU
4:3 stretched at 1280×960 or 1440×1080 gives the best performance. Lower pixel count drastically reduces GPU load, allowing higher clock speeds without thermal throttling and keeping 1% lows stable during smoke and particle effects. Player models also appear 33 percent wider making them easier to track.
Should I enable or disable FSR in CS2
Disable FSR (set to Highest Quality). FSR 1.0 introduces shimmering on edges and blurs long range targets which hurts competitive visibility. The FPS boost is not worth the clarity loss. Only use FSR Quality mode on very weak hardware like RX 580 or integrated graphics.
What shadow settings should I use in CS2
Set Global Shadow Quality to Low or Medium and Dynamic Shadows to Sun Only or All. Recent updates decoupled these settings. You can lower Global Shadows for better FPS while still seeing enemy shadow projections around corners. This gives massive performance gains without losing tactical information.
Why does my CS2 stutter on AMD GPU after driver update
Shader cache invalidation causes stutters when new visual effects compile for the first time. After driver updates, reset shader cache in AMD Software, let the game sit in main menu for 5 to 10 minutes, then play a Deathmatch match to force all assets to load and compile.
What is Smart Access Memory and should I enable it
Smart Access Memory (SAM) allows your CPU to access the entire GPU VRAM frame buffer instead of 256MB chunks. This reduces CPU overhead when CS2 streams textures and geometry. Enable it in BIOS by turning on Above 4G Decoding and Re-Size BAR Support. Benchmarks show significant 1% low FPS improvements.
Should I disable Radeon Chill and Radeon Boost
Yes, disable both. Radeon Chill dynamically adjusts FPS based on mouse movement which creates variable input lag. Radeon Boost drops resolution during fast flicks which blurs enemies exactly when you need to see them. Both features hurt competitive consistency.
What launch options should I use for CS2
Use minimal launch options: -freq 240 (your monitor refresh rate), -novid, -console, and -nojoy. Do not use -high, -threads, or old CS:GO networking commands. Source 2 has a sophisticated scheduler that makes most old launch options obsolete or actively harmful.
Why does my mouse feel floaty in CS2 on AMD
Floaty mouse is usually caused by frame buffering or V-Sync. Ensure V-Sync is off in both driver and game settings. Enable Anti-Lag 2 in AMD Software and CS2 video settings. Disable Radeon Chill and Radeon Boost. Right click cs2.exe and check Disable fullscreen optimizations under Compatibility tab.
