Noko, your favorite game <b>Serious Sam</b> has an interesting stat, minimum sustained framerate. This seems to be a good indicator of the worst case graphic scenario. Of course, it only applies to the <b>Serious Sam game</b>, itself.
(Noko, I know you already know about this. This is for the other readers).
There is a nice Serious Sam demo/test which can also be used for benchmarking. <A HREF="http://www.avault.com" target="_new">http://www.avault.com</A> is one place to get it.
1. Pressing '~' to activates the console.
2. /dem_bProfile=1 starts the benchmark routine.
3. Run any demo and return to the console to see the results.
4. Quality video settings probably should be used for benchmarking purpose.
Also, included with the Serious Sam Demo/Test is something called "Technology Test". This is a cool demonstration of 3D functions like reflections, texturing, bump mapping, fog, particles, translucency and transparency, etc.
There is a disclaimer that the demo is only a test not a demo game yet you seem to be able to play some standalone combat and some on-line, as well. (I haven't tried the latter).
From what I have seen this is a cool game. The best way I can desribe it is it's like the FPS Genre original, Doom II, only with state of the art 3D graphics. The Serious Sam arenas are huge. (Keep in mind, I just looked at the demo and only for about 20 minutes).
I'm definitely going to pick up a copy.
