Hi To do post-processing effects I need to render to render targets that are the same size as the back buffer. I had a look at the TextureCaps.SupportsNonPower2Conditional caps bit however I'm not sure that I've found the correct flag because the limitation of no dependent texture reads seems rather...limiting. Is this the right cap? Thanks

What card are you using? Most cards (all that I know of) will internally convert textures to a square base 2 texture. If you make a 1024x768 texture, it may actually become 1024x1024. I am pretty sure any card within the last 5 years (surely any Radeon or GeForce cards) supporrt non base-2, but I cannot be sure.

Thanks Sir!

I have a newish GeForce FX 5200 and is does support the non-pow-2-conditional cap but is it the right cap?

Cheers
