Timedemo is a console command available in Source to benchmark your personal computer with a demo.

To record a demo, type record "name" while in a game server. This will record a demo called name.dem.

To benchmark, open console and type timedemo filename

This will play a demo as fast as possible and print the performance results to the console.

EXAMPLE: 535 frames 1.565 seconds 341.77 fps (2.93 ms/f) 47.449 fps variability

To print the performance results to a text file, type timedemo filename stats.txt

This will create a text file called stats.txt to, e.g. hl2\stats.txt (You can find your demo files there too.)

Commands

timedemo <demoname> <optional stats.txt> : gets demo speeds, writing perf resutls to the optional [[stats.txt]]

timedemoquit <demoname> <optional stats.txt> : gets demo speeds, writing perf resutls to the optional [[stats.txt]]

Limitations/Bugs

Warning:Playback of demo files can be used as a benchmark, but may not reflect actual in-game performance.

Tip:Disable vertical sync (VSync) (-forcenovsync command line argument) and set fps_max high enough in order to play demos with timedemo at higher rate...

Confirm:What about accuracy?

timedemo is a console command available in all Source games.
