I have a geforce Fx 5600 256mb and I download the last dirver for XP 4.93 i guess. and then Something happen.. Like black Lines ( like big squares) or sometimes it divides halp the screem , and its crazy.. I have to restart the pc , to get it work .. And this didn't happen before..
I Had to downlooad the last driver cause of Dx9c support.. And I guess that the problem is the DirectX9.c Thing... cause with 9.B it did not happen...
And.. I noticed that If i activate post processing it appears, and if i turn it off.. its solved..( But thins black things with post processing on , just happen sometimes..) I already though about by another card..
