The driver settings that affect shader reuse differ by GPU vendor: NVIDIA provides a disk-space limit (and Linux OpenGL cache controls), AMD offers an optimized cache setting and a reset action, and Intel offers downloadable precompiled shaders for eligible systems and supported Steam games. These controls can affect whether shaders are reused or compiled again, but none is a universal fix for stuttering. Leave defaults in place unless you are troubleshooting a specific, reproducible issue.
What shader-cache settings change
Games and graphics drivers compile shaders into forms the GPU can use. When a usable compiled result is cached, it may be reused instead of being generated again. Disabling a cache, clearing it, or letting a size limit evict entries can mean more compilation work the next time a game needs those shaders.
Cache controls are not interchangeable. Their availability depends on vendor, operating system and sometimes graphics API. The official material cited here does not establish a universal cache-size setting or a cross-vendor performance gain.
NVIDIA: set a cache size in Windows or configure Linux OpenGL
Windows Control Panel
In NVIDIA Control Panel, open Manage 3D settings and find Shader Cache Size. It sets the maximum disk space the driver may use for compiled shaders. NVIDIA lists these choices: Disabled, Unlimited, 128 MB, 256 MB, 512 MB, 1 GB, 5 GB, 10 GB and 100 GB. Near the limit, older shaders are removed; NVIDIA warns that a limit that is too small can evict shaders still in use and contribute to gameplay stutters. Choose a limit that can accommodate the games you normally play while remaining within available disk space. NVIDIA Control Panel: Manage 3D Settings.

NVIDIA says installing a new driver deletes its shader cache. As a result, the first run after an update may stutter while shaders are compiled again; that alone does not show that the cache-size setting is wrong.
Linux OpenGL
NVIDIA’s Linux 550.76 documentation describes these OpenGL-specific controls:

__GL_SHADER_DISK_CACHEenables or disables the disk cache.__GL_SHADER_DISK_CACHE_PATHsets its location.__GL_SHADER_DISK_CACHE_SIZEsets its size.GLShaderDiskCacheis an X configuration option; the environment variables override it.
These details apply to NVIDIA’s Linux OpenGL driver, not as general Windows or Vulkan controls. In that documentation, caching is normally enabled for direct rendering by a non-root user, disabled by default for direct rendering as root, and disabled for indirect rendering and setuid/setgid binaries. Cached files persist between application runs but are driver-version-specific, so changing driver versions causes recompilation. NVIDIA Linux 550.76 OpenGL environment variables.
AMD: keep Shader Cache optimized unless troubleshooting
AMD Software sets Shader Cache to AMD optimized by default and offers a global option to disable it. AMD describes the cache as storing frequently used game shaders rather than regenerating them each time, which can help loading times and reduce CPU usage. The feature controls reuse; disabling it removes that benefit. AMD: Configure Radeon Settings for gaming.

AMD Software also provides a separate Reset Shader Cache action. Treat a reset as a targeted troubleshooting step, not routine maintenance: after clearing cached shaders, the driver may need to compile them again. AMD’s cited guidance does not establish that globally disabling the cache or repeatedly resetting it is a general stutter fix. AMD: Customize Graphics Settings with AMD Software.
Intel: Precompiled Shaders are a separate download feature
Intel’s Precompiled Shaders feature downloads pre-optimized shader files rather than offering a general cache-size limit. On eligible systems, Intel Graphics Software and the driver check for files that match the hardware and driver configuration, download them from Intel’s servers and cache them locally. The feature is disabled by default on supported systems; enable it in Intel Graphics Software under Graphics → 3D Rendering → Precompiled Shaders.

Eligibility requires an eligible Intel GPU family, Windows 10 or 11, driver 32.0.101.8626 or newer, an internet connection for the download, at least 1 GB of disk space, and a Steam-installed game on Intel’s supported list. Unsupported games continue to use standard shader compilation. Intel says downloaded files can be used offline after the initial download, and updated files are downloaded when available for a new driver version. Files are typically under 100 MB per supported game, according to Intel, though requirements vary. Intel Precompiled Shaders: requirements and setup.
Intel estimates 20–50% faster initial loading times with Precompiled Shaders, but says results vary by game and system configuration. This is Intel’s estimate, not an independent cross-vendor benchmark or a guaranteed result for an individual game. Intel also says the feature does not change visual quality.

What to check when shader compilation causes stutter
- Identify the scope. Check your GPU vendor, operating system, graphics API and control software before changing a setting. A Linux NVIDIA OpenGL variable, for example, is not a general Windows setting.
- Consider recent driver changes. A driver installation can clear shader data: NVIDIA says its Control Panel cache is deleted on driver installation, while Intel says a clean driver installation clears its shader cache. Allow any reported shader processing to finish before changing cache controls.
- Check whether reuse is limited. Confirm that the cache is not disabled or, for NVIDIA, capped so tightly that it may evict shaders for the games you use. AMD’s default is AMD optimized.
- Reset only to test a specific problem. A reset or clear can require shaders to be recreated, so subsequent runs may involve more compilation work. Compare the same game and conditions before and after rather than assuming the reset helped.
- Verify Intel feature eligibility. For Intel Precompiled Shaders, check the GPU family, driver version, Windows version, Steam installation and supported-game list, and confirm the download completed before expecting the feature to help.
Intel Arc pauses immediately after a driver update
Intel says shader processing after a graphics-driver update can cause brief gameplay pauses on Intel Arc Graphics. Its guidance for that scenario is to let processing reach 100% before fully starting a game; Intel says performance should then stabilize. This advice concerns the described post-update Arc behavior, not every instance of stutter on other GPUs or during ordinary repeat play. Intel: stuttering after installing an Arc graphics driver. Intel also documents clearing the cache during a clean driver installation. Intel: clean installation of graphics drivers in Windows.
Which setting should you change?
| Vendor and scope | Control | What it affects | When it is relevant |
|---|---|---|---|
| NVIDIA Control Panel, Windows | Shader Cache Size | Maximum disk space for compiled shaders; entries may be removed near the limit. | When checking whether caching is disabled or the space limit is too restrictive. |
| NVIDIA, Linux OpenGL (550.76 documentation) | Enablement, path and size environment variables; X option | OpenGL disk-cache use, location and size, subject to the documented rendering and user conditions. | When configuring this specific Linux OpenGL driver behavior. |
| AMD Software | AMD optimized; global disable; Reset Shader Cache | Default cache behavior, whether caching is disabled, or a manual cache reset. | Keep optimized by default; use disable or reset only for a specific test. |
| Intel Graphics Software, eligible systems | Precompiled Shaders | Downloads and locally caches pre-optimized files for supported Steam games; not a generic cache-size control. | When hardware, driver, operating system and game meet Intel’s eligibility requirements. |
Use the control that matches your vendor and symptom. If a hitch starts just after a driver update, first allow any documented post-update shader processing to finish; changing cache settings does not prevent every form of stutter.
