You still need to apply the fix.
The latest version was just compiled against the SDK, but the message spewing that seems to contribute to stuttering still persists.
By adding NumberOfPumps=0 to the ini, this stops and seems (for allot of folks on the Discord I am in) fixes the issue.
I just helped someone with this an hour ago who has a 4090 and was a stuttering mess. He implemented this and the stutters went away.
You won’t hurt anything by testing it out.
