full procedure right here:
1.start Q3
2. at menu screen, push tilde- the ~ key- to bring down console.
3.type in exaclty this:
/timedemo 1
and push enter.
4. Push tilde to close console.
5. Use Q3 menu to chose a demo and play it as normal.
6. After it plays thru, pull down console again and look to it's bottom left and WHAMMO there's your FPS.
If it dies at step 5, you need to patch your Q3 to at least 1.27. Other versions broke the demo functions, it got really hard to timedemo for a while. Or use the installed, unpatched, straight off the CD version instead. No matter what Q3 version you have, use the first demo in the list to benchmark.
That oughta do it! Oh, and uh.. Shouldn't this be in the Games section?
PS- you MUST add the / before any commands or Q3 interporets it as a chat. Also, to loop demos you must use the Q3 language to write a config file to tell it to do so-
to make all this easier, goto
G256.com and get the Q3bench program, it will do it all for you. PHAT program.
