I noticed that if I enable _any_ nonzero speed optimization in CFLAGS, even -O1
or -Og, I get drastic performance improvement in GTASA, although the sound
sometimes still appears choppy. But any attempt to use -msse3, -march=native or
-O3 (or combinations thereof) gives small if any improvement.
The same picture is when I only recompile mixer.c adding optimization options
instead of whole Wine source.

It seems strange that by default Wine doesn't enable any optimizations at all.
(Tested on wine-3.1-286-g389c3ad.)
