Symptoms

Game didn't stutter until about a week or so ago.

Game plays well for the most part, but moving around from place to place causes stuttering. I think is caused by shaders not being pre-cached (or loading from the cache slowly?). I enabled both Enable Shader Pre-caching and Allow background processing of Vulkan shaders. However, now, when the game starts it doesn't seem to show the little pre-compiling shaders dialog anymore.
