Silent Hill Homecoming is buggy game, absolutely different and developed by another company. One more brand is lost in business. Okay, i tried to make some bugfixes, but they solve problems only partially, not everywhere. Can't play this game, patch or modify it, it's too bad for Silent Hill fan like i am.
This is universal patch and it allow to run some other games properly on single core cpu or fix problems for old Radeons 1300-1950 series. Some users use it in Mass Effect to increase performance.
