I have been having performance issues in D3. Here are my specs:
Here are my specs:
32-bit Vista (FML...)
Core 2 Quad 2.50GHz
4GB Ram, 3.3GB Available
ATI Radeon HD 4850 with 1GB dedicated video RAM
300GB Hard drive, 10,000RPM, about half full if that matters

This is a machine that runs ME2 at max settings without issue and runs Skyrim reasonably on high settings, yet D3 here has major performance issues at even the lowest graphical settings. I understand my graphics card is a bit dated, but even then it still meet, hell it DOUBLES, the recommended VRAM requrements. WTF is up with this? Is D3 really that unoptimized, or is my machine worse than i think it is?
