Stuttering frequently on highest and lowest settings.

Today's patch mentioned in the notes: Added support for Unreal PSO Caching (shader pre-compiling) to address and reduce the amount of shader stuttering experienced on PC. 

Is this actually in there and working properly? I saw no longer load times the first time after the update, no indication of the shader compilation process happening as seen in most other games that have such features, no obvious activity and crunching of the CPU & SSD like you get when shaders are compiled up front in other games. Is just super quick and done in the background? Is there an option we have to manually enable to start the shader pre-compilation found in some outliers like SF6? (didn't see anything new in the menus of WRC).

The gameplay of WRC now exhibits fewer severe stutters occurring, so the update definitely seemed to have some improvements there, but there's also way more frequent microstuttering happening now. At first glance from what the experience was like loading up the game after the update, it seems more like the developers reduced the severity of the shaders being cached on the fly rather than actually pre-compiling all of them up front as there's still a lot of minor hiccups and micro-stuttering during gameplay. It's impossible to assume or measure what's actually going on from our end, however. It's all very... mystifying. The only certainty is DX12 truly sucks with all this crap. 

Anyway, thanks for the update! Hope you all can still iron out the bugs and performance issues and poor hardware utilization happening on high end CPUs and GPUs. I know it was a selling point and feature to come later, but VR support still seems completely unfeasible in this game's current state.
