The next time you are in the same loading screen, the driver can skip some of the work and use the cache. The multiple passes and compaction can be replaced by a single NVReorderThread call. You must log in or register to reply here. As a result, the first time the game is played, the result is not buttery smooth, but after a title has loaded its Shaders in the Shader Cache and is then replayed, the result is significantly better. SER is a performance optimization that unlocks the potential for better ray and memory coherency in ray tracing shaders, and thus increased shading efficiency. First, I will tell you the answer first. Small thing but you should move PoE shader cache outside of C:/Users (disk C:/ is fine). It needs to be compiled whenever a gamer performs an action, and the Shader for that is not found in the Shader Cache. "Change Shader Cache" Size to 10GB in NVIDIA control panel. Nvidia Click Perform Reset and then OK to delete the Shader Cache. While testing if there was difference when using the shader cache or not we noticed that if the shader cache is enabled in the driver settings then the game is loading completely single core, while normally, without ENB or even with ENB + shader cache disabled the game uses 100% CPU. Today we will talk about the Shader Cache setting in the NVIDIA Control Panel.
