I have a quick yet rather ambigious question (but don’t worry, I’m not asking you to help me with an exact, specific problem ) Here’s my general problem:
I have an Athlon 3000+, 1024 of PC3200 and a TI4600. The application I’m developing currently has a textured sphere of a couple thousand tris using a single, 2048 x 1024 texture of Earth ( Blue Marble is win ). My sphere does some spinning, but that’s pretty much the extent of his liveliness.
Now, doing all this fun stuff in display lists, I’m getting a mighty 78 fps (without DLs it was around 50). This seems mighty slow to me, so I figured I’d ask all of you out there for some general opengl optimization rules, without having to make you suffer through reading a bunch of my code.
I know a little bit about VBOs, but haven’t gotten to the point of implimenting them yet. Seems like I’ve probably got something more fundamentally wrong than just the raw vertex pushing power, though, so I figured I’d ask you gurus for some basic suggestions
Also, one other little question. Does anyone know of a profiler specifically for OpenGL (on windows). I found a bunch of stuff about OpenGL Profiler for Mac, but nothing for Windows. Anyway, thanks for any advice!
