Deus Ex Human Revolution benchmarks:

Vanilla benchmarks:

wine-1.7.1 vanilla = 72 fps (glitches)

wine-1.7.1 vanilla + threaded-opts = 115 fps (glitches)

wine-1.7.1 vanilla + threaded-opts + StrictDrawOrdering = 51 fps 


CSMT benchmarks

wine-1.7.1 csmt disabled = 75 fps (glitches)

wine-1.7.1 csmt enabled = 120 fps 

wine-1.7.1 csmt disabled + threaded-opts = 115 fps

wine-1.7.1 csmt enabled + threaded-opts = 114 fps

Given that StrictDrawOrdering is required to remove rather bad graphical
glitches, the performance improvement from Vanilla to CSMT is 51 to 120 fps or
a 235% performance increase. The big gain is from not having to use SDO in this
game since threaded-opts alone approaches CSMT performance (115 fps)

As a side note, the older buffer hack gets around the same performance as
vanilla + threaded-opts but has the same graphical glitch issues.


In contrast, I did not notice any performance improvements for CSMT with Skyrim
although the older buffer hack did result in a 200% performance increase. This
was with an older version of wine (1.5.30) so perhaps there has been a
regression for Skyrim, though.
