memory usage and number of polys in Q2

[Guest]

Hello, i was reading some of the discussions here and didn't find any information about memory usage of the Q2. I would like to know if it is possible to get answer to these questions:
- Memory usage for textures per frame?
- Memory usage of temporary data per frame?
- Typical number of polygons per scene?

It would be interesting to find these numbers for other 3D games as well.

Can anybody answer the questions above? I realy hope that people who can answer read these discussions.

Well, the cvar "r_speeds" when set to "1" will tell you a lot of similar data, such as the number of polygons onscreen and such.

The memory useage per frame would really be based on the resolution used, and the bits per pixel. Also, textures are not loaded per frame. The entire level is cached before hand while the level loads. The only thing that is done "per frame" is the 3D viewpoint calculations and the actual blitting to the display. A 320x240x16bit display is 1228800 bits. Unless we're talking about a paletted color set, in which case it would be significantly lower, which is probably the case since the textures are colored via palette.
