I am looking for some assistance with increasing the performance and/or provide GPU priority to ustation, using an ATI FireGL V3100 Video card. The Video card specs are as follows; ATI FireGL V3100 400MHZ 128MB Bios version: 113-A33414-101 Driver version: 8.293.0.0 The PC is an HP workstation XW4200, P4 HT 3.2GHZ, with 1GB RAM, running Windows XP Pro SP2. I notice that when rotating an drawing, with the display mode set to Constant (and graphics Accel turned on), the image rotation is choppy. This is not an overly large drawing. Any recommendations? The RAM usage is about 300MB at most when I am rotating the image. If this was a RAM, CPU or Hard Drive issue, I could resolve this easily by killing off services, but this appears to be video GPU intensive, which I am not sure how to resolve.
