Likewise, hardware ray traced reflections and translucency, which have complex interactions with materials and lighting, will also see benefits. Reddit and its partners use cookies and similar technologies to provide you with a better experience. This could happen when you clean-install a new driver and some games have to rebuild the cache, TW3 will stutter badly with a fresh driver install for a good while and probably some others games too. Applying SER allows the path tracer to reduce divergence in its material evaluation, instead of just on the number of bounces. From what I have noticed with the current Nvidia drivers (511.79) the NV_Cache folder exists no longer even though shader caching is enabled in the global settings in Nvidia Control Panel. This is possible due to the decoupling of tracing and shading. Unreal Engine developers can take advantage of SER within the NVIDIA branch of Unreal Engine (NvRTX).

Path tracing presents a highly divergent workflow, making it a great candidate for applying SER. For instance, the most critical shader programs which must be available as soon as possible after startup could be manually saved, while less frequently used shaders rely on the cache. Translations into other languages may not provide the same linguistic quality. 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. I checked with our dev team. "Change Shader Cache" Size to 10GB in NVIDIA control panel. In addition, the driver sometimes needs to generate shaders internally for certain clear and copy operations. 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. Users/players should then consume the cache by enabling r.UseShaderCaching and r.UseShaderPredraw. 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. The macro version can be enabled by #defining NV_HITOBJECT_USE_MACRO_API before #including nvHLSLExtns.h. Data divergence occurs when different threads access memory resources in patterns that are hard to cache. Because the Shader Cache only helps players improve their gameplay and has no negative side effects, it is best to leave the Shader Cache turned on during games rather than changing the setting.

Shader compilation is the process of taking that representation and sending it to the host GPU driver to get compiled and then executed on the user's GPU. For optimal performance, we chose to run the garbage collection when a game is launched (you do not want it running in the background all the time). This example is the tip of the iceberg when it comes to the potential of the path tracer code. In the absence of the Shader Cache, the game will not be able to run smoothly and will not achieve constant frames per second, which affects the gameplay and leads to a highly nagging experience for players. Using the default shader cache size for most systems is the best option (logically, because thats probably why its the default).
