How do you increase frame rate?

Yeah to be honest once the dynarec is done CPU usage will be far less of a worry that your GFX card but it's surprising how many resources the windows shell can snatch up.

For me, the graphics processor was the only thing needed to upgrade in order to get high consistent framerates.

Remember that Supermodel is not the same as MAME. Supermodel actually utilizes the Video Card, whereas MAME only uses the Processor.

I tried upgrading the GPU and nothing else. No need to upgrade CPU or RAM. I'm getting no slowdown in SCUD at 1280x960 and it looks amazing.
Specs:
-E7300 Core 2 Duo 2.66GHz
-4GB RAM
-Nvidia GT 220

I had an Nvidia NVS 290 before and I could barely get SWTrilogy to run at 640x480.

I hope this helps people out there who are wondering if they need to purchase a new rig or just upgrade one component.
