Hi!
I'm trying to benchmark some hardware using a simple OpenGL 3d app that draws a few objects using some OpenGL primitives and some glu/glut calls. I'm compiling under vc++ 6.0 and running on Windows XP. I have a FireGL T2/128 running ATI's latest FIREGL driver (8.223).
I get a pretty consistent frame rate unless I happen to access the ATI control panel while the app is running. For example, if I change the resolution (from 1280 x 1024 to 1024 x768 ) and then click "No" at the dialog box asking if I want to keep the new settings, I get almost a 100% boost in framerate that's consistent no matter how much longer i keep the app running. The same thing happens if I rotate the screen 90 degrees and then back again. I haven't tried going back a rev. of the driver, but I was wondering if anyone's seen this on a firegl or even a radeon card with Catalyst. I'd definitely appreciate any help.
Thanks!
