Should add that if I switch over to wine-staging and use CSMT performance comes way up overall but the stuttering is still a major problem.
How about CSMT off with staging? Does it change anything?
With CSMT turned off, performance is identical to vanilla wine.
In both cases, the stuttering behavior reported here is frequent. The only difference is the average frame rate with CSMT on improves significantly but frequent frame time spikes are still common. It is still always a problem when effects/shaders need to be rendered for the first time entering a map.
I imagine this still an issue related to Comment 11 of this bugzilla report.
