What is direct shader cache and how do you use it?

Direct shader cache is a directx feature which stores the shaders and textures of recently used games, allowing them to be loaded faster than if they were streamed from your hard disk. This is an important optimization for gamers as it significantly improves load times and reduces stuttering when loading new levels or areas in games.

What we will do today is explain what direct shader cache is, how you enable directx 11 direct shader caching on Windows 10, and why you might want to disable direct x11 direct shader caching entirely.

What is direct shader cache and how does DirectX 11 direct shader caching work?

A direct shader cache is a type of cached graphics driver that stores compiled shaders in memory.

DirectX 11 direct shader caching works by using the GPU to compile all required shaders for each game at startup, and then storing them on your hard disk (or SSD). The next time you run the game, Windows will simply load the cached shaders from disk, rather than recompiling them. This can make load times faster and reduce frame lag.

DirectX direct shader cache files are named dxcpl.dll, dxgccache.sys or dxgcache32.sys (for 32-bit versions of Windows) and stored in the %SYSTEMROOT%\SysWOW64 (for 32-bit versions of Windows) or %SYSTEMROOT%\System32 (for 64-bit versions of Windows).

Why you might want to disable direct x11 direct shader caching entirely

If you are experiencing crashes, direct shader cache might be the cause. If it is stopping your game from running properly then delete direct x11 direct shader caching files to fix the issue. However if you do not need or want this feature on for other reasons then disable directx 11 direct shaders cached.

What Is Windows Disk Cleanup?

What Is Windows Disk Cleanup


Windows Disk Cleanup is a free Windows program that can help you clean up your hard drive. Using the tool, users are able to search for files on their computer they no longer need and delete them without having to do it manually themselves.

Does Disk Cleanup delete everything?

Let’s get rid of some unnecessary files and free up space on your computer. The Disk Cleanup tool can quickly remove various system files and free up disk space, but you shouldn’t get rid of every single file it recommends removing because sometimes there are ones that need to be kept like “Windows ESD Installation Files” on Windows 10. For the most part, though, the items in Disk Cleanup are safe to remove; however, you should always double-check before deleting anything just to make sure nothing important will go missing from your laptop or desktop PC.

It will show you a list of files after scanning, including delivery optimization files, Windows ESD installation files, previous Windows installations files, and anything else with a similar name.

What Is Safe to Delete in Disk Cleanup?

Except for the following files (Windows ESD Installation Files), if you are not going to do any of these things then it is safe to delete almost all other system and temporary files from Disk Cleanup.

How do I turn off the shader cache?

Disable shader pre-caching by unticking the “Enable Shader Pre Caching” box. Click OK to save your changes and return back to this page. In settings, click on Steam then open its properties tab again and uncheck that same option in there as well (Shaders).

Some other things that can be done with the help of a graphics card


Textures are used to add details and realism to models, but the more textures a model has, the more resources it requires.


There are several types of anti-aliasing, but the most common form is MSAA or multi-sample anti-aliasing.

anisotropic filtering

Anisotropic Anti-Aliasing (AF) improves upon ordinary Trilinear AF by reducing grainy appearance in surfaces that run at oblique angles to the camera.

How do I disable cache shader?

On below you will see how to disable cache shader step by step:-

  1. Visit  “NVIDIA Control Panel” 

  2. Choose "3D Settings" under "Display". 

  3. Set Shader Cache to "Off."

How do I activate the shader cache

To make Shader Caching active, here are some steps to follow: – Visit Radeon Settings and select the Gaming tab. – In the top right, click Add and then Browse. – Select EliteDangerous64.exe from the game directory.

How do I turn off the AMD cache shader?

  1.  First, Open Regedit by typing it in the search box on the task bar, go to HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Control\Class / 4d36e968-e8764 -11ce-bfc1-08002be10318/ 0000/UMD.

  2. Now, convert ShaderCache from 30 00 (on) or 31 00 to 32 00 (off).

  3. Save and Reboot for this optimization.

How do I clean my Nvidia shader cache?

Let's delete the Shader Cache from Your System: step by step:-

  1. Start by going to NVIDIA control panel
  2. Choose Manage 3D Settings
  3. Uncheck Shader Cache, then hit Apply.
  4. Restart your PC.
  5. Visit %username%\AppData\Local\Temp\NVIDIA Corporation\NV_Cache.
  6. Delete the contents of the folder (You may just copy and paste that address into a Windows address bar).

Is it safe to delete the Nvidia cache?

For those of you who do care about the small amount of space used by these folders and files, it's completely safe to remove them. Just uninstall all Nvidia software from your system before deleting anything!

Can you delete Installer2 Nvidia?

If you remove the Installer2 folder, none of your current NVIDIA drivers or programs will be affected. However, it might just prevent full installs from taking place if you're using an older OS driver from the store.

The Bottom Line

DirectX is the direct3D graphics application programming interface that's used to create video games and other 3-dimensional computer graphics. This post has gone over what direct shader cache is, how it can be enabled or disabled, why you should never delete direct shader cache files, and more!
