Hello all. My computer prefers DirectX9 over DirectX10 for DX9 games. I don't play any DX10 or DX11 games. My computer also seems to like Windows XP more than Vista or 7. I had 7 installed for awhile...but then I backed up all my files and took a day to perform a clean install. Now I'm running XP Professional 64-bit. (Yes, I know it's actually a modified version of Windows Server 2003...) Now my computer runs very nicely. The performance is very nice. Oblivion, though, isn't cooperating with the shift. I have an in-game reverb effect that refuses to go away. The effect does NOT exist when I run Oblivion on Vista or 7, nor does it exist in other games or apps. Just Oblivion on XP. It sounds similar to a reverb effect, or a lowpass effect...or something of that nature. Everything sounds like it's underwater, muffled, distant, etc. To make matters more interesting, I can "fix" the issue by lowering my hardware acceleration to "basic". When I do that, however, the game lags a ton. That's most likely because of the emulation. So what do I do? I find it funny how most people are trying to enable reverb effects, while I can't seem to get rid of it. Oh, and Google didn't turn up any results. Please help. Thanks in advance. :)
