OpenGL PBO Sample

<1> Stevie-O: just switch to orthographic projection and turn of depth buffering <1> then render it to the screen like any 2d obj. <2> hmmk <1> Anyone around that knows much about VBOs or something faster than vertex arrays, i'm getting really bad performance in some places and i dont know why <3> Hrm. I know a bit :P again, I use d3d more now <1> yea <1> well <4> I know PBOs pretty well, but I don't know much about anything dealing with geometry <1> for some reason i'm getting some pretty awfull slowdowns using vertex arrays <1> I wonder if its all the state changes or the rendering <1> b/c d3d is a lot faster <1> and i copy the data twice with d3d <1> I looked at VBOs for opengl once, trying to find more info on it now, but it looked like it only worked for indexed geometry <4> I think now that the PBO extension is out, you can put pretty much whatever you feel like in the buffer <3> they work pretty much the same as regular vertex arrays <3> except you put the data in the vbo first <1> what is PBO ? <1> maybe i'll kill setting the rendermode and see if its the state changes causing the slowdown <1> i'm on a 7900GT and only getting like 10fps in some demos when my d3d gets 50
