alright so i've just recently got an nVidia 7800 from a buddy, i know it's not a highend card but it's still a big upgrade from my old 32 mb ati.

Now i was wondering what are some capabilities of the card or techniques i could use to speed up my program? is there such thing as displaylist that run on gpu? where do i read on how to utilize the gpu and the memory of the card?


thanx in advance.

Check the programming guides over here for good advice on perf

http://developer.nvidia.com/page/home.html

Plenty of other goodies there too - heaps of demos, tools, artwork, etc..

A displaylist always run on gpu, I don't get you ?
To use the memory : use plenty of high resolution textures
To use the gpu : use GLSL vertex and fragment shaders

VBO for big meshes : http://www.ozone3d.net/tutorials/opengl_vbo.php?lang=2

What does your program do currently ?

thanx i'll look into those articles.

i used to think displaylist was running on software end for some reason =S but i realized that now as soon as i implemented it the frame rate quadrupled, on my other card it barely made a difference.


this is my program :

i'm just writing code as i learn so this is to help me understand certain techniques better. for now i got a terrain with some md2 models than can be controlled by the mouse you can click to select and right click to tell them to move. i know the picking isn't efficient the way that i'm doing it.
