How to clear cache of Nvidia and AMD GPUs? Is it necessary?

How to clear the cache of GPU like Nvidia and AMD and whether is it necessary? That’s precisely I plan to discuss here. GPU cache is often overlooked but it is a crucial aspect of GPU cache management.

What is GPU Cache?

If you ever wondered why your graphics card seems to handle those complex visuals so effortlessly? A big part of that comes from the GPU cache. It as a high-speed, on-chip memory directly integrated into the Graphics Processing Unit (GPU).

It’s like a super-efficient middleman between the GPU and the comparatively slower main system memory. This cache keeps frequently used data and instructions right at the GPU’s fingertips, ready for instant access.

So, what kind of data are we talking about? Everything from textures, shaders, to other rendering-related information.

This setup doesn’t just make your games look good; it also means that machine learning models and scientific computations run smoother and faster. The GPU cache essentially reduces latency and boosts overall performance, making it a cornerstone of modern graphics processing.

Comparison to CPU Cache

How GPU cache stacks up against CPU cache? While they both serve similar purposes, there are some key differences. GPU cache is generally larger and more intricate compared to CPU cache because GPU workloads are highly parallel and data-intensive. They need a more sophisticated caching mechanism to handle the sheer volume of data being processed.

CPU cache stores both data and instructions, but GPU cache primarily focuses on data. Graphics and compute-intensive tasks are more data-driven, necessitating a more specialized cache. This complexity is what allows your GPU to render stunning visuals and handle massive datasets with ease.

Importance of GPU Cache

The GPU cache isn’t just a bare add-on; it’s critical for the overall performance of your graphics card.

By acting as a high-speed buffer between the GPU and main memory, it mitigates the impact of slower main memory access times. This means the GPU can fetch and process the necessary data more efficiently. The result? Faster rendering, smoother animations, and better performance in graphics-intensive applications.

Imagine playing a high-end game and experiencing lag or choppiness—pretty frustrating? The GPU cache helps prevent that by ensuring the GPU has quick access to the data it needs, keeping your gaming experience seamless and enjoyable.

Why Clear the GPU Cache?

Over time, the data stored in the GPU cache can become outdated or irrelevant. New data is constantly being loaded and processed, but the cache doesn’t automatically delete old or unused data. This leads to a gradual buildup and depletion of available cache space.

‘When the cache is filled with outdated or unnecessary data, the GPU’s efficiency takes a hit’. This can impair its ability to access and process the required information, resulting in a noticeable drop in overall performance.

If you notice your system slowing down or encountering errors when starting graphics-intensive applications, clearing the GPU cache can be a valuable troubleshooting step. A bloated and inefficient cache can lead to performance degradation. Clearing it allows the GPU to start fresh, optimizing its performance and resolving many common issues.

Importance of Regular Maintenance

Regularly clearing the GPU cache helps maintain the overall efficiency and performance of your graphics card. By removing outdated and unnecessary data, you ensure that the GPU has access to the most relevant and frequently used information. This leads to improved responsiveness and faster processing times.

In the same way you might defrag your hard drive or clean out your system’s junk files, clearing the GPU cache is a crucial maintenance step.

Is it Safe to Delete the GPU Cache?

Interestingly, there’s no dedicated button or option in the BIOS or software to clear the GPU cache. This suggests that the cache is designed to be somewhat self-managing. It’s intended to be a transparent and self-regulating component of the GPU, with the system automatically managing the cache’s contents to maintain optimal performance.

However, this doesn’t mean manual clearing is off the table; it’s just less straightforward.

While clearing the GPU cache is generally safe, a few precautionary measures can ensure you don’t run into any issues. Before deleting the cache, back up the cache folder. This way, if the deletion causes any unintended consequences, you can restore the cache and revert the changes.

How to Clear the GPU Cache

Windows 10 and 11

For Windows 10 and 11 users, the built-in Disk Cleanup utility is your best mate. Open Disk Cleanup, and look for the “DirectX Texture Builder/Shader Cache” option. Selecting this will target and remove graphics-related cache files, giving your GPU a fresh start.

Empty the cache and remove junk data


NVIDIA GPU users can clear the cache through the NVIDIA Control Panel. Navigate to the “Manage 3D Settings” section and locate the “Shader cache” option. Disable it and save the changes. Additionally, you can manually delete the Dxcache, GLCache, and NV_Cache folders located within the Temp directory.


Clearing the cache on AMD GPUs is straightforward using the AMD Radeon software. Open the software, navigate to the Graphics tab, and select the “Reset shader cache” option. The software will then proceed to clear the cache and save the changes.

Keyboard Shortcut

For a quick way to access the Temp folder, press the Win + R keys to open the Run window. Enter the command “%temp%” and press Enter. This will directly open the Temp folder, where you can locate and delete the cached files.

Memory Allocation and Visual Effects

To further optimize your GPU’s performance, consider allocating more memory to the GPU in the BIOS. Increasing the available cache space can help the GPU handle more data, improving its overall efficiency. Additionally, disabling visual effects in Windows can reduce the GPU’s memory consumption, freeing up resources for other graphics-intensive tasks.

Driver Updates

Keeping your GPU drivers up-to-date is crucial for efficient memory usage and preventing issues related to the cache. Outdated drivers can lead to compatibility problems or suboptimal cache management. Regularly check for and install the latest driver updates from the GPU manufacturer’s website to ensure optimal performance.

While not all users will encounter a full or problematic GPU cache, understanding how to effectively manage and clear it can be a valuable troubleshooting tool when experiencing performance issues with graphics-intensive applications.
