640x480 @ 32fps
64fps @ 320x240, all it took was..

P4 2.8Ghz and a gig of RDRAM PC1066

PCMark2002: 7100/6900/1100
3DMark2001 SE: 15000 (Radeon 9700 Pro.. Not that it makes a difference AVS-wise)

320x240 pixel-doubling off is the way to go. Twice as fast as 640x480 with pixel-doubling on.

Congrats on a studly system.

Don't know how this fint into troubleshooting though. :p

Yeah, but what preset were you viewing? i can also get 32 frames in 320x240 if i only add a simple oscilliscope with clear every frame on :p

And i have a 266mhz Pentium 1! :p :D :p :blah: :blah: :blah: :p :D :p

HAHAHAHAHA!!!

I made a few presets that get 20-30 fps at 800x600 w/o pixel doubling. On my 1GHz Athlon.

Why would you ever want more than 20fps anyway, you can't see the difference beyond that.. its not like in quake where you can 'feel' fps and you really do need 50-60fps. I think that the human eye inputs at roughly 15 fps, thats why 30 is so often quoted as an ideal figure.

BTW, running at low res without pixel doubling can ruin the scale of things sometimes. It can make things over-blocky and too big.

EDIT: Do you want to know why it is faster without pixel doubling? It is because of the refresh rate of your monitor, at high res the monitor can not refresh so fast.. I only noticed that recently when I found that my framerate would never go above 100 in my window and it would never go above certain numbers in various fullscreen modes (20.0 @ 1024x768, 33.3 @ 800x600, 45.0 @ 640x480). I'd expect it varies depending on your graphics card and monitor.

Jheriko: Find options that say 'Wait for retrace' and DISABLE them. You will find your FPS will skyrocket.

And with overlay mode, pixel-doubling 640x480 is the same as 320x240 mode. And if you have an S3 Savage4 8MB card, search for JGC's tweaked driver so you can run overlay mode at 1600x1200 without pixel-doubling (on other drivers this would normally crash something).

Yeah but without 'wait for retrace', you get ugly tearing in the image.

By the way, this doesn't make sense to me:

640x480 @ 32fps
64fps @ 320x240

Given the fact that 640x480 is 4 times as large as 320x240, the FPS should logically be more like 16 and not 32.

Speed depends on the preset anyway.

Yes but then it won't be drawing to the screen any smoother or faster, only to the buffer, which will cause those annoying cuts across the screen.

Well, if you have a card tweaking program, turn on triple buffering and also keep wait for retrace on. This basically means it 'lags' one frame to eliminate visual tears and also run at full speed.

w00t! I'm now getting almost 250fps with some really fast presets in a window. :)
