You will now need to select your C: Drive and click OK ( Work your way through the other drives if you have more than one) 3. The description below is heavily distilled and focuses on one specific configuration: Lumen reflections with hardware ray tracing (HWRT) hit lighting enabled. The option of using Shader Cache or not depends entirely upon the player, but it is highly recommended to keep the setting turned on mainly because it does not put any significant stress on the hardware but yields a lot of benefits, some of which are as follows: Keeping the Shader Cache turned on is a great way to enhance the gameplay and reduce the overall badgering & stuttering effect that some players experience during the more demanding games. The lighting conditions, fog, and transparency are some of the different dynamics that vary from one situation to another during the gameplay. *Warning: This hasnt been tested enough to say that it's safe* The Riva TNT2 was a graphics card by NVIDIA, launched on October 12th, 1999. Related: Manually update NVIDIA GPU driver. Use The cache should be populated by enabling r.UseShaderCaching and r.UseShaderDrawLog on a development machine. Shader Cache saves all interactions and textures that occur during gameplay in memory so that when you encounter a similar situation in the future, the system does not have to load all of this information all over again, reducing stuttering caused by such heavy graphical usage. A change increasing the default size of the shader disk cache will be made available in the next driver release series (after 455). How To Clear DirectX Shader Cache In Windows 10, clear the DirectX shader cache within Windows 11. For instance, the most critical shader programs which must be available as soon as possible after startup could be manually saved, while less frequently used shaders rely on the cache. Below are the steps to delete DirectX shader cache from a Windows 10 computer. BFV generates over 400mb files in NC Cache. Do not run an overclock on your GPU/CPU. When an application specifies a shader source, the driver first searches the cache to see if it has already compiled this source with the current version of the compiler. Turning on the shader cache does not mean an automatic load; it builds the cache the first time you run the game. During gameplay, the dynamics keep changing all the time. Suppose you are an avid gamer who likes to spend hours in gameplay regularly.
