<pre>Thanks, I tested the patch and it seems to work fine.
Game CPU utilization dropped nearly to half from >100%. The load is now spread
more evenly between cores, earlier one core was (almost) fully loaded. On my
test machine, speed remains about the same, so no regressions. FPS seems to
fluctuate a bit more (~3%), I'm not sure why, but I don't think that a problem.</pre>
