Stuttering and NVIDIA shader cache
Hi. Ever since I got Witcher 3, I´ve been having sporadic stutter and hitches, no matter what i do. I´ve tried a number of different settings, tweaks, nvidia control panel settings, optimizing the PC, different nvidia drivers. My PC is an Core i7 6700K @ 4.4 GHz, MSI Z170A Gaming M7 motherboard, G.Skill Ripjaws V DDR4 3000 16GB memory, MSI GTX 980 Ti Gaming 6G, etc, Windows 10 x64 and the PC is pretty optimized for games. I have very high fps in this game, at the highest of settings, but it still sometimes stutter.
After investigating and trying pretty much about everything, I came into something interesting. When I delete the nvidia shader cache contents, next time I start up Witcher 3 the game will stutter, but the more I play, the nvidia shader cache folder will fill with files, and then the game will play much better, very smooth. If I turn off the shader cache off in nvidia control panel, the game will start stuttering again. The only way to have the game smooth is by letting shader cache fill over time, and in the next 2 to 3 restarts, the game will be smooth. As the nvidia shader cache is a temporary folder, if you let some program like CCleaner to delete it, the game will stutter and the cache would build all over again and the game will be eventually smooth again once the cache is filled. Notice that, if you play a lot of games at the same time, it will be filled with different files for the various games, and maybe Witcher 3 will stutter, as the shader cache temportary folder is limited by size (I think 256 MB or something..)
It seems then, that the game doesn´t handle this feature very well and some stutter issues are related to this, at least in my case.
Anyone experincing something like this? Thoughts?
