Video Card Benchmark Test
(This is actually a little note for myself as I keep forgetting the command.)
Here's how to load Nexuiz's ingame video card benchmark test:
1. Launch the game.
2. Press SHIFT + ESC.
3. In the console that drops down, type "timedemo demos/demo1" without the quotes.
4. Press enter. At the end of the timedemo, the game will display its minimum, average, and maximum frames per second.
IMO, this is one of the best Quake 2-based freeware downloadable PC games.
