What GPU cache is and why clearing it helps

Your graphics card (GPU) stores temporary data in its own memory, separate from your computer's main RAM. This cache holds textures, shaders, and other graphics information that programs use repeatedly. Over time, this cache can grow large and contain outdated or unused data, which slows down your graphics performance and can cause stuttering, lag, or crashes in games and graphics-heavy applications.

Clearing the GPU cache removes this temporary data and forces your graphics card to rebuild it fresh. This is different from clearing your regular hard drive cache — it specifically targets the memory on your graphics card itself. The process is safe and takes just a few minutes, and your GPU will automatically rebuild what it needs the next time you use graphics-intensive programs.

Key Takeaways

  • GPU cache is temporary data stored on your graphics card that can accumulate and slow performance over weeks or months.
  • The fastest method on Windows is to restart your computer, which clears GPU cache automatically.
  • NVIDIA and AMD graphics cards have their own driver control panels where you can manually clear cache without restarting.
  • If you use integrated graphics (Intel or AMD built into your CPU), clearing cache happens through Windows settings rather than a separate driver panel.
  • Clearing GPU cache does not delete your files or settings — it only removes temporary graphics data.

The simplest method: restart your computer

The easiest way to clear GPU cache is to shut down and restart your computer completely. When you power off, your graphics card loses power and clears all temporary data from its memory. This is the most reliable method because it clears cache from any graphics hardware you have, whether it is a dedicated card or integrated graphics.

straightforward click the Start menu, select Power, and choose Restart. Wait for your computer to fully shut down and boot back up. This takes a few minutes but requires no technical steps. If you have been experiencing graphics lag or stuttering, restart your computer first before trying other methods.

Clearing cache on NVIDIA graphics cards

If you have an NVIDIA graphics card, you can clear cache through the NVIDIA Control Panel without restarting. Right-click on your desktop and look for NVIDIA Control Panel in the menu. If you do not see it, open the Start menu, search for "NVIDIA Control Panel," and click it to open.

Once the Control Panel is open, look for the menu on the left side. Click Manage 3D Settings, then find the tab labeled Global Settings. Scroll down until you see Shader Cache. Change this setting from "Driver Default" to Off, then click explore. Wait a few seconds, then change it back to "Driver Default" and click explore again. This cycle clears the shader cache, which is the largest part of GPU cache.

After you do this, close the Control Panel. Your NVIDIA card will rebuild its cache the next time you run a graphics program. You do not need to restart your computer for this to take effect.

Clearing cache on AMD graphics cards

AMD graphics cards use the Radeon Settings panel. Right-click on your desktop and look for Radeon Settings or AMD Radeon Settings. If you do not see it in the right-click menu, open the Start menu and search for "Radeon Settings" directly.

In Radeon Settings, click the Gaming tab at the top. On the left side, select Global Graphics. Look for Shader Cache in the list of options. Set it to Off, then click explore. Wait a few seconds, then set it back to On and click explore again. This clears the AMD shader cache without requiring a restart.

Close Radeon Settings when you are done. Your AMD card will rebuild cache the next time you launch a game or graphics process.

Clearing cache on Intel integrated graphics

If your computer uses Intel integrated graphics (built into your CPU rather than a separate card), the cache clearing process is different. You cannot access a separate driver panel like NVIDIA or AMD users can. Instead, restarting your computer is the most straightforward method.

If you want to try clearing cache without restarting, open the Start menu and search for Device Manager. Click it to open. Expand the section labeled Display adapters by clicking the arrow next to it. Right-click on your Intel graphics adapter and select Disable device. Wait 10 seconds, then right-click it again and select Enable device. This forces Intel graphics to reinitialize and clear its cache. However, restarting your computer remains the most reliable approach for Intel integrated graphics.

When to clear GPU cache and what to expect

Clear your GPU cache if you notice stuttering in games, graphics glitches, or if a graphics-heavy process crashes repeatedly. You should also clear cache after updating your graphics drivers, because old cached data can sometimes conflict with new driver versions. Some people clear cache monthly as routine maintenance, though it is not necessary unless you experience problems.

After clearing cache, you may notice a brief pause the first time you launch a graphics program — this is normal and happens while your GPU rebuilds the cache it needs. Performance should return to normal within seconds. If you clear cache and problems persist, the issue may be something else, such as overheating, outdated drivers, or a hardware problem.

Keeping your GPU drivers updated

Outdated graphics drivers are a common cause of cache-related problems. NVIDIA, AMD, and Intel release driver updates regularly that improve performance and fix bugs. You can check for updates through each company's control panel.

For NVIDIA, open NVIDIA Control Panel, click Help at the top, and select Check for Updates. For AMD, open Radeon Settings, click the gear icon in the top right, and select Check for Updates. For Intel, search for "Intel Driver & Support Assistant" in the Start menu and run it to check for updates. Keeping drivers current often prevents cache problems from occurring in the first place.

Frequently Asked Questions

Will clearing GPU cache delete my game saves or settings?

No. GPU cache contains only temporary graphics data that your card uses while running programs. Your game saves, settings, and all files on your computer remain untouched. Clearing cache is completely safe and does not affect anything you have stored.

How often should I clear GPU cache?

Most people do not need to clear GPU cache regularly. Clear it only when you experience graphics problems like stuttering or crashes. If you play demanding games or use graphics software heavily, clearing cache once a month is reasonable, but it is not required for normal use.

What is the difference between GPU cache and disk cache?

GPU cache is temporary data stored on your graphics card itself. Disk cache is temporary data stored on your hard drive or SSD. They are separate systems. Clearing one does not clear the other. Restarting your computer clears both, but you can clear GPU cache alone without affecting disk cache.

Can I clear GPU cache while a game is running?

You can try, but it is not recommended. Clearing cache while a graphics program is active may cause the program to crash or behave unpredictably. Close all games and graphics applications first, then clear cache. This ensures the process completes safely.

Why is my GPU cache so large?

GPU cache grows naturally as you use graphics programs. Games, video editing software, and 3D applications all add data to the cache. Over weeks or months, unused data accumulates. This is normal and not a sign of a problem. Clearing cache periodically prevents it from becoming so large that it affects performance.
