NVIDIA and AMD shader cache: when to clear and when to leave it
Shader cache is compiled GPU effects stored on disk. After a big game patch, a Game Ready or Adrenalin update, or weird stutter right after a reboot, clearing it is reasonable. Close the game, clear NVIDIA or AMD cache, launch, and play a 10-15 minute warmup. SmoothWizard offers Clean shader cache (NVIDIA / AMD / Intel / DirectX) in the tray. That is not a daily Temp-style habit.
The first minutes after an update often hitch because the GPU rebuilds shaders. Clearing cache on a stable game only repeats the same compile pass.
Why it stutters
Drivers and games cache compiled shaders so the next launch starts faster. After a patch, on-disk entries may not match the new engine or driver build, which shows up as micro-stutter or long pauses on first draw. Clearing removes stale files. The next session still has to rebuild them, so the first minutes can feel worse until warmup finishes.
Key points
- Clear after a game patch, a major GPU update, or odd stutter - not every week.
- Game closed. Then warmup on DM or range before ranked.
- SmoothWizard: Clean shader cache in the tray. Power plan is Basic, not the same thing.

Check if cache is the likely cause
Hitches right after a Steam, Valorant, or GPU update often mean shader compilation. If the game was fine yesterday and hitches today with no update, check overlays and power plan first. Cache stays for update-day problems.

Close the game and stubborn launchers
Clear cache with the game exe closed. Steam, Riot Client, or Battle.net may keep a process alive. Do not delete folders manually while the game still runs.

NVIDIA: panel or SmoothWizard
The NVIDIA App sometimes exposes a clear shader cache option (path varies by version). In SmoothWizard: tray icon > Clean shader cache > NVIDIA. Same class of operation without digging through AppData.

AMD: Adrenalin or tray
In AMD Software: Adrenalin Edition look for Graphics > Reset Shader Cache or similar (wording shifts between builds). Or Clean shader cache (AMD) in SmoothWizard. Restart the game after clearing.

Warm up instead of instant ranked
After clearing, run range, DM, or bots for 10-15 minutes. Hit a few maps or rounds. Then queue. No borrowed FPS numbers - you judge whether the frame feels normal again on your PC.

SmoothWizard
Tray: Clean shader cache (NVIDIA, AMD, Intel, DirectX). Basic: power plan. PRO: process pause on fullscreen. The app does not compile shaders for the game or replace a driver update.
Notes
NVIDIA App and Adrenalin labels stay English where the UI shows English. SmoothWizard copy calls the same on-disk GPU cache folders shader cache.
FAQ
Click a question to show the answer. The first one is open.
Should I clear shader cache every week?
No. Use it after a patch, driver update, or when a stable game suddenly hitches without overlay changes. Weekly clearing mostly extends warmup.
Does clearing remove in-game graphics settings?
No. It targets GPU compile cache on disk, not Valorant or CS2 config files. Game settings stay in their own folders.
Does SmoothWizard clear cache automatically?
Only when you click Clean shader cache in the tray. It does not run on every Windows boot.
Intel or DirectX only?
The SmoothWizard tray also lists Intel and DirectX. On hybrid laptops you may clear both after a big update if the title uses iGPU paths.
