Removing the extra overhead of storing, compacting, and relaunching work is often worth a 20% savings. . 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. It also helps with loading times when the game is sending a lot of shaders to the drivers. Applying SER allows the path tracer to reduce divergence in its material evaluation, instead of just on the number of bounces. Data divergence occurs when different threads access memory resources in patterns that are hard to cache. So its easier for you next time to clear your Nvidia driver cache. Turn off Shader Cache. To clear the NVIDIA graphics Shader Cache in Windows, follow these steps: Open the NVIDIA control panel. If it does not then you could always try updating your DirectX. This offers a 20-50% gain in performance with the code change provided below: This improvement can be accomplished by replacing the DXR TraceRay function with an equivalent set of NvTraceRayHitObject, NvReorderThread, and NvInvokeHitObject. Next, add the fake UAV slot to the global root signature used to compile ray tracing pipelines. Furthermore, the cache files become invalid every time a new driver is installed. This new cache size feature simply just allows you to control the amount you save. Shading divergence can pose performance problems when considering both data and execution. 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. NVIDIA recently introduced a new feature available in the next generation of GPUs called Shader Execution Reordering (SER). Of course, if youre playing a game like PUBG, which is (how can I put it nicely :-D) not optimally programmed, you can try disabling the shader cache to see if it has a positive effect, but in general, it shouldnt.

The shader cache and the functions to read and load binaries are not mutually exclusive. The shader cache is enabled on read/write file systems by default. This improves efficiency of complex ray tracing calculations and will provide greater gains in scenes that take full advantage of what ray tracing has to offer. Thus I recommend using the Shader Cache size option and choosing the unlimited option for the best possible outcome. Applications can avoid this overhead by saving and loading programs directly. The implementation described above resulted in a 20-30% speed increase in Lumen reflections on the GPU, measured when profiling a typical workload in UE5 City Sample. SER mitigates divergence by reordering threads, on the fly, across the GPU so that they can continue execution with increased coherence. Click Perform Reset and then OK to delete the Shader Cache. It is only after the Shader Cache has been filled that players can enjoy the whole experience offered by the title. The cache persists between application runs, so that with a thorough initial test run, compilation need only occur the first time a new driver is installed.
