First, I will tell you the answer first. Shader cache is simply the method of saving these compiled shaders onto your drive so the next time they're called again (i.e loading the same map or using a heavily animated attack move again) they are called straight from the drive instead of having to be recompiled in real-time, makes it easier on your system to render the next scenes. In addition, the driver sometimes needs to generate shaders internally for certain clear and copy operations. SER is a performance optimization that unlocks the potential for better ray and memory coherency in ray tracing shaders, and thus increased shading efficiency. It is only after the Shader Cache has been filled that players can enjoy the whole experience offered by the title.

It has always bothered me that an opponent might have a technical advantage in 1 vs. 1, so I have always looked at every possible setting and spent a lot of time researching and testing to get the most out of my existing hardware. Applying SER allows the path tracer to reduce divergence in its material evaluation, instead of just on the number of bounces. 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. You can skip the junction link solution because your main disk is SSD, so NVidia Shader Cache are on faster disk. Open the NV_Cache folder and Delete all the files in here. Below are the steps to clear your NVIDIA cache on a Windows 10 or Windows 11 computer. Next, add the fake UAV slot to the global root signature used to compile ray tracing pipelines. Some of the options of the Shader Cache size include: if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'raiseyourskillz_com-large-mobile-banner-2','ezslot_16',875,'0','0'])};__ez_fad_position('div-gpt-ad-raiseyourskillz_com-large-mobile-banner-2-0');This is a new option that has been provided to players after driver version 496.13. This is the reason for the separate re-tracing path with hit lighting. Before I installed this latest version of Nvidia drivers I routinely cleared this NV_Cache folder; however, it never was located in AppData\Local directory for me, it was always located in C:\ProgramData\NVIDIA Corporation\NV_Cache. Shader Cache is extremely vital, especially considering the heavy-duty games that we are used to these days, which can easily range in sizes of several Gigabytes. I just noticed i have this option and it seems new to me called : Shader Cache Sizeit has multiple options. Note: This article was written in English. You still haven't answered if you use a HDD or not, so we cannot know if that could be the cause of your stutter, a HDD will slow things down, moreover considering games on PC are not even close to being optimized like in a console and even more if its not a very fast HDD. We have read your feedback and are taking this into considering for future improvements to the shader cache implementation. and our To do this, you just need to delete the corresponding folders of the respective game.
