The DirectX shader cache can cause many problems so if you have been having a few graphical issues with some games, programs, apps, or even your web browser, then clearing the DirectX Cache might be the answer to resolving the problems. Shader cache is simply the method of saving these compiled shaders onto your drive so the next time they're called again (i.e loading the same map or using a heavily animated attack move again) they are called straight from the drive instead of having to be recompiled in real-time, makes it easier on your system to render the next scenes. This is possible due to the decoupling of tracing and shading. Although the cache eliminates the need to recompile shaders, there is search and maintenance overhead. You still haven't answered if you use a HDD or not, so we cannot know if that could be the cause of your stutter, a HDD will slow things down, moreover considering games on PC are not even close to being optimized like in a console and even more if its not a very fast HDD. re-enabling shader cache and testing now. _____ Power to the Developer!
