Oh i went off topic myself a little. Here is what i mean. GTA4 is in the background, CoD in the front.
Left side - BEFORE, Right side - AFTER. As you can see it is semi-transparent so you can see through walls, without being detected. But I want to do this without making the game have 1x1 pixel textures, so it wont look like crap.
this would be new and undetectable, because it is a driver and ati tray tools wont need to be running for it to work
