I was planning on buying heretic 2, But have the demo version of the game and get some slow down while playing the game and in other parts it runs fine. So my question is does the heretic 2 patch work??? I read this its meant to stop the slow downs but would like to know if it does rather than running out and buying the game for £25 and not enjoy playing it, I'm using the 160mhz PPC card does this thing just not have the guts to play games?
