Re: VERY LOW FPS MASS EFFECT 1

There's one very specific issues I had once, and the chances are low that you have it as well, but I'll tell you anyway.

I use the tweaks to enable surrounds sound and environmental audio (which  have described in a sticky thread). This resulted in frame drops for me, because while I had a supported sound card with EAX, it was software emulated, which put more strain on my CPU. So if you have hardware audio enabled, disable it and see if that changes anything.

Another possible issue is an incompatibility with recent Nvidia drivers. I've had issues like that a lot when I still had a Geforce card. You should try installing an older driver version.
