If you are having issues with your AMD graphics card then you can also clear the AMD shader cache easily. If you are using Windows 11 then the methods are the same and you can still clear the DirectX shader cache within Windows 11. With increasingly complex renderer implementations, more workloads are becoming limited by shader execution rather than the tracing of rays. The consent submitted will only be used for data processing originating from this website. Unreal Engine developers can take advantage of SER within the NVIDIA branch of Unreal Engine (NvRTX). How to Configure Radeon Software to Get an Optimal Gaming Experience | AMD Open up File Explorer > Type %localappdata% into the address bar and press enter 2.

If delete "%UserProfile%\AppData\Local\ATI\" folder and, enter the registry that ShaderCache_DEF (type REG_SZ and set 2) (If there is ShaderCache registry, it should be deleted) and, restart the system, shader cache feature will be turned on for all DX11 games. Hi, I have my game installed on an NVME, while my shader cache is being generated on another driver, we used to have an option to change that but I think it was removed, I'm having huge loading screens where the performance graph fills the shader bar, so how can I change my cache to the same drive now? Thank you for your feedback. . SER in Unreal Engine 5 (UE5) enables better offline path tracing, arguably the most complex tracing operation in UE5.

Other games seem to cache their stuff on their own files, so countless driver changes don't even affect them one bit and other games may stutter a few seconds when you start them and then they just settle down just fine. I've had an issue with first run after yesterday's video driver update. Apparently the stock shader cache for a lot of Nvidia cards is only set at 256MB, and this game uses a very heavy shader cache so setting the shader cache to 10GB in the Nvidia control panel made my game stable with no crashes till I turned it off after 5+ hours of play. Applying SER allows the path tracer to reduce divergence in its material evaluation, instead of just on the number of bounces. A change increasing the default size of the shader disk cache will be made available in the next driver release series (after 455). Under the Global Settings section, scroll down and turn off Shader Cache. The actual cause of game stuttering during gameplay is that the shaders provided by game developers are generic and must be explicitly converted to those for your GPU. JavaScript is disabled.
