Hey there pplz, Ive been creating a pretty ''crapy'', as some may call it, gaming engine for personal use mainly, and have come up with a problem concearning textures. Is there any OpenGL commands or techniques i could possibly use to cut back on some of the cpu usage involved in displaying these 7kb jpeg images? I don''t even mind if the textures become a little dodgy. Also, does anyone know how to keep a game going at a constant frame rate? --> another problem ive been having. Cheers -- jANuS

First of all, you need to be more specific on why its running slow. How many vertexes are in the scene and how many are you sending to OpenGL? (Are you just sending everything and letting OGL sort it out? )
Last try multiplying everything by the milliseconds since your last rendering over 1000 (1000ths of a second, then if you want something to move at 2 m/s do this: var += 2*timesincelastrender; )

hope that helps

Play around with textures filters

Optimize by grouping your primitives/polygons by states changes.
Don''t forget that OpenGL is a state machine (as any electronic device) even if it''s an API.

So you must avoid doping costly change often.
Group by texture, material...

(Have a look @ OpenGL.org website, there are severals examples/helps)

Thankyou All! I cannot begin to believe how much my scene has sped up!
