This is semi-related to my previous topic.
Im curious as to what other ppls experiences are
tests @1440x1080 nvidia geforce9500 (512mb) 128bit bus winXP
framebuffer noAA 117fps
FBO noAA 107fps
framebuffer 4xAA 99fps
FBO 4xAA 27fps!!!
framebuffer 4xAA + using copytexsubimage to copy FB into a texture 76fps
So whats up?
It seems like with decent resolutions’s + AA Im much better off just rendering to the FB + then doing a copytexture, which seems cockeyed to say the least.
What are other ppls experiences on various hardware?
NOTE - if I drop the resolution down to 640x480 then framebuffer 4xAA + using copytexsubimage + FBO 4xAA are about the same speed
