I've got the ARB_ shaders going now, but keep hitting the damned 2D vs RECT problem when using the shaders I wrote for the Mac! I think the rectangle extension might work on windows using GLEW though.
Rectangle textures are working on Windows now. Performance is still horrible though. Currently 40% of a 3.4Ghz P4 to get a 640x480 photo-jpeg to screen at 30fps. About 25% or so is the decompression, which is bad but the rest might be an indication of a non-optimal pixel format or something?
I still need to figure out if YUV textures are a reality on the PC or not...
The FireGL 3100 card I have here is missing all of the YUV extensions. Not good.
Can you give me the info on the support for rectangle and YUV textures on a NV card?
rectangle textures work (but i have no numbers in my head); i have experimented with YUV but never got it to work.
attached are the glewinfo-output for the same machine in w32 and linux.
