In shader code, define the fake UAV slot and register again, using the same values: Now the SER API may be used in ray generation shaders: 1) ensure that templates are enabled in DXC by specifying the command line argument -HV 2021. The consent submitted will only be used for data processing originating from this website. You can skip the junction link solution because your main disk is SSD, so NVidia Shader Cache are on faster disk. The main advantage offered by the shader cache is that it is handled automatically, without any application intervention. It needs to be compiled whenever a gamer performs an action, and the Shader for that is not found in the Shader Cache. RaiseYourSkillz.com is compensated for referring traffic and business to these companies. A recent version of DXC / dxcompiler.dll that supports templates (optional). This is the reason for the separate re-tracing path with hit lighting. The pass roughly becomes trace near field, if not a hit trace far field, if either hit then uses the hit object to evaluate the material and perform lighting. 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. and our re-enabling shader cache and testing now. Fps drops+Shader bar spikes. What the cache does is, instead of having to compile the shader, the driver can skip this step the next time and use what's saved in the cache. But unfortunately, the first interaction with the game does not define the gaming experience for players. For NVIDIA cards, its in the NVIDIA Control Panel under 3D Settings > Manage 3D settings. The first time does not translate to once as it takes a few times to write a cache, after that it just reads frequently used data and relieves your disk of that duty. If the cache is enabled, these too will only be generated once, rather than every time the application is run. Run it as administrator.
