This tool is designed to safely and thoroughly clean your computer's shader cache.

The unique feature of Shader Cache Deep Cleaner is its fully automated process. While many other tools require you to manually adjust settings, restart your computer, and then delete the files, this tool handles everything for you. With just a single click, you initiate a process that manages everything: from preparation and the mandatory reboot to the final cleanup and the correct reactivation of the cache.

Why should you clean your shader cache?

Over time, or after updating your video drivers, the stored shader cache can become corrupt or outdated. This can lead to graphical artifacts ("glitches"), stuttering, or reduced performance in games and simulators. Cleaning this cache forces the computer to rebuild it cleanly, which often resolves these issues.

How does it work?

The tool operates in two phases to ensure that all files can be deleted safely.

Phase 1 (Before the reboot): Prepares the system. The tool temporarily disables the shader cache and schedules a cleanup task to run after the next restart.
Phase 2 (After the reboot): As Windows starts up and before the cache files are in use, the tool performs the actual cleanup. Afterward, the shader cache is re-enabled, and the tool cleans up after itself.

Once the cleanup is complete, a pop-up will appear with the results.

This will show you how many files were moved and how much disk space was freed up.

Congratulations! The process is now complete. Your shader cache has been cleaned, and you can start your games or simulator again.

For information:

Some users are experiencing a virus warning. I want to reassure everyone that the tool does not contain a virus. This is a case of false positives from some antivirus programs.

The tool is flagged as suspicious because it has to intervene deeply in the system to properly clean the shader cache: It temporarily modifies a registry setting and uses the Windows Task Scheduler to perform the cleanup after a reboot. These actions are performed completely safely and restored to your original settings after rebooting. These are powerful features that some scanners (especially those with AI/heuristics) incorrectly flag as suspicious.

!!: I've since submitted the file to Microsoft for analysis as a false positive detection. It can take a few days to a week for Microsoft to update the false virus lists. After that, the message should disappear and the program should work smoothly. Because the virus scanner likely deleted the EXE file, we recommend reinstalling the entire tool from the zip file to your PC. Thank you for your patience.
