01.What is Shader Cache and why does it freeze your game?
The **Shader Cache** is a database that your NVIDIA driver creates to store pre-compiled codes from your games' graphics engine. This should speed up loading, but when the cache gets too large or corrupted (especially after a driver update), it causes constant micro-stutters.
If you feel that your Windows 11 is lagging even in simple menus or that your FPS is fluctuating, cleaning the DXCache and GLCache folders is the mandatory technical cleaning step.
Pro Config: Shader Cache Size
In the NVIDIA Control Panel, we recommend setting the Shader Cache Size to **Unlimited**. This prevents Windows from overwriting important files but requires you to do manual cleaning (or automatic with Voltris) if the driver changes.

02.How to Clean Manually (Without breaking the Driver)
You should close all your games and navigate to:
%LOCALAPPDATA%\NVIDIA\DXCache
Delete everything possible inside this folder. Some files may be in use by Windows; ignore them. Repeat the process in the GLCache folder. This will force the system to rebuild the performance 'map' in a pure and stable way.
03.The Advantage of Voltris Ultra Cleaner GPU-Fix
The **Voltris Ultra Cleaner** has an exclusive module for cleaning video kernels that Windows ignores.
- **Deep Driver Flush:** Cleans records from old driver versions that conflict with the current one.
- **Auto DXCache Reset:** Schedules periodic shader cleanings to ensure PC stability.
- **VRAM Management:** Frees up video memory reserved by zombie Windows processes.
Don't do it Manually.
