Quote:Why the game is so slow even with hardwareA quick run ( http://www.pasteall.org/18163 ) with GPU Perfstudio on a HD4850 tells that we are draw call bound on windows (a lot of small meshes). The GPU is waiting for the driver 2/3 of the frame time resulting in a framerate of about 40fps.
But it also means that we could use much more complex meshes for the tracks/trackobjects without losing framerate.

Are you absolutely sure that you aren't issuing too many draw calls? The GPU being idle 2/3 of the time seems quite high.
In this test:

that racing game, which has a little bit better graphics than vdrift, dropped below 40 fps only at the highest resolution and the absolutely highest settings on an HD4850.
Also, last time I checked, some car models took more than 2 minutes to load.

I think you're both saying the same thing. Saying "draw call bound" means "the bottleneck is the draw calls".

Whoa, what? You mean when you're selecting a car it takes 2 minutes to load? Or did you mean when you start the game and the track loads?
