dang it,

i was hopeing youd mabey get "Need A Diffrent Format" or something just so we could work out whats going on...

[Jim]

Checked all that, and glGetError returns GL_NOERROR too.
I tried it on my Quadro FX1400 and my GeForce MX and it works OK.

if its supported in the mx line it *should* be fairly compatible.

does pbuffer stuff run on your x1600 jim? cause im thinking it might be the most compatible route as i dont want to make demos that only a few people can veiw.

does pbuffer stuff run on your x1600 jim?

I don't know

I rechecked this on my Vista X1600 and it's working fast and well now, so it was a driver problem.  I also checked it on my Vista 8600GT and it runs, but about 1/10th the speed of the ATI.  Not sure whether that's just because it's crap running in a window on nVidia, or what.

great! and thanks for the updated info jim.

its weird it works faster on your ati board, would you like a fullscreen version to test?

[Jim]

I'm going to do some experiments of my own, including a comparison with pbuffers

Jim

[ninogenio]

cool..could you keep the forum updated on your findings jim,

i really like fbo's for simplicity but until they are a bit more on the stable side i think ill use pbuffers.

[stormbringer]

FORGET PBuffers!!!!

they are buggy, not very advanced in terms of what you can do with them and VERY VERY SLOW!!!

FBOs are the way to go: clean, fast, etc

[Jim]

I implemented both, you get a FBO if your card supports them (you're right, they're great, but we had terrible problems with early Vista drivers), and if not, you get a pbuffer.  If it works, it works, if it breaks, tough!

Jim, FBOs work really fine, the problem is that almost all the drivers for Vista are not that stable yet... but that's really the way to go....

Nino (and gang!)
It works great on my sony vaio laptop (nVidia GeForce 8400M GT) - smooth as a silk dude!

Nice work!
