Wow...you learn something new every day.
My system: P3 1ghz@1.33ghz, 512mb PC133, GF3 Ti200 (at 200/500), W2K Pro
JK2 setup: 1024x768, everything on medium, 16bit color (yeah I know, but I am addicted to smooth running games, not 32bit color)
The above timedemo gave me 70FPS...not bad I think, but I'd like to see what other people are getting on their systems. So post your results here...
