--- Comment #10 from Mikko Rasa tdb@tdb.fi 2008-05-11 16:44:46 --- No effect on SupCom, and a +d3d trace doesn't show the patched function being called at all.
I tried to take a backtrace with gdb, but couldn't get suitable breakpoints inserted. Backtracing by hand failed due to my complete lack of knowledge about Direct3D.
