So I have a custom built desktop. It was actually out of commission for awhile because of bad power supply. I recently got it running again, installed Windows 7 x64, and purchased a few new games. I feel like the framerates I am getting are lower than what they should be. The specs are:
Motherboard: Asus m2n sli-deluxe
CPU: AMD AM2 dual 4200 (2.21 GHz)
RAM: 6 GB ddr 800
Video: Nvidia 7950 GX2 1 GB PCI E
Hard Drives: They are older than the comp is, 7200 RPM I believe.
I turn everything down to minimum on team fortress and still get framerates in the low 20's in lots of action. I was wondering what my bottleneck might be. I am curious if Windows 7 might cause a lower performance because of being new (optimized drivers?, etc?). Also I wonder if the virtualization of the 32 bit games is causing any lower performance? Any insight would be greatly appreciated.
Enter the nVidia control panel and make sure you have Multi-GPU mode enabled. This sets both GPU's on the 7950GX2 to work together in a sort of Pseudo-SLI mode (some argue that true SLI requires 2 cards and an SLI bridge, but the dual GPU card solution gives you basically the same thing).
