Promising suggestion, although it's not clear why this would cause issues
unless there was a graphics API change or something.
However, I'm unable to try it out since that variable doesn't appear to do
anything. There's no performance difference and the process log doesn't contain
entires about "fill_cpu_override" (as it should according to a googleable
post).
Does this need a specific Wine version or parameter to function?
