I have only gfx5200 and rendering to npot 2d textures doesn't work, but I can use them for texturing - software fallback (very sloooow). I tried nvemulate and rendering to npot 2d textures didn't work so I assumed this doesn't work at all. Probably this is only not done in software.

@ Humus and Nitro
Nvidia does support rendering to NPOT TEXTURE_2D with FBO. I've used this feature without incident with both int and float NPOT textures on every nvidia driver release with FBO support. It is also true that nvidia only supports 24-bit depth attachments, so you may want to switch to 24-bit for compatability purposes.

Hi thanks for the reply, i've upgraded to 5.8cats. Normal control panel

Demo works fine and looks great on my rad9700pro and i get 150-300fps

Nice job!!

ATI supports both 16 and 24bit depth buffer. I used 16bit because I didn't need any more bits than that.
How come Nvidia doesn't support NPOT GL_TEXTURE_2D? Wasn't NPOT textures one of the selling points of the 6800?

xg8, yes, your drivers are too old. Only the latest couple of drivers have FBO support.

There is also problem with depth renderbuffer. 16bit depth renderbuffer doesn't work. Need 24bit to work on nvidia. Does Ati's FBO support only 16bit depth renderbuffer? Or was there another reason to use 16bit in this demo?
BTW nice demo

Weird, anyway i\\\'ve seen nitro\\\'s post about fbo with his nvidia card.

Maybe my drivers are too old to run it.

Dosen't work on my Rad9700pro, it says no fbo support, i'm using cats 5.1 as these seems best for battlefield 2, I'm not a programmer etc. Can someone explain what fbo means?

It won't work on my 7800GTX! I posted in the forum but it's rarely checked!
