I recently have noticed some odd little graphical problems when I play any game on my computer. This is relatively a newish (1-2 months) problem, and I can't for the life of me figure out what the problem is, as it never really happened before. With certain types of graphics, small lines or boxes appear around them. It happens mostly with things that are cloud or glow effects, mostly on spells and the like. It almost looks like the graphics engine is trying too hard, and showing the borders of the effect as well. The cloud effects also seem to be really square and boxy as well. Some transparent colours also appear too intense, becoming almost opaque. This whole problem started as far as I know when I installed Neverwinter Nights 2, but it effects my whole system now. I am using the most current version of DirectX, and the drivers for my ATI Radeon X550 are also up to date. Any idea what might be causing the problem, and/or how to fix it?
