So if I play with (iLightCS_Mode=3, iCriticalSectionMode=3), that will be useful to you?
Yes. Maybe. If you play with those settings, experience lots of stutter, and I read your log file, I might make out some information about which critical sections and which calls are producing the stutter. Then I could conceivably... discover a critical section that should be suppressed, or some code that has an easy way to optimize it, or something. Conceivably, maybe, just possibly. Really, all possibilities are long shots at best, but everything in current versions of OSR / FSR was a long shot that paid off, this whole project is pure black magic.
Anyway, yeah, a log or two of stutter on other peoples computers, with profiling (iLightCS_Mode=3, iCriticalSectionMode=3) enabled would be nice. I can examine stutter here, but different installs encounter different sources of stutter.
