NVidia & non-square textures

I'm having trouble with a game using my Nvidia 6600. Chat on the net leads me to believe it's because the game uses non-power-2 texture sizes. Is there any known workaround for the gfx card if this is the case?

Non-square textures and non-power of two textures are two completely different things. Which are you talking about?

It's true. I suggest designing your game so it only ever uses square textures for compatibility.

Very Quick fix is to resize your images into 256x256, 512x512 etc. Long fix is to tile/segment your images into smaller chunks of square textures.

Good point... which am I talking about. Looking at the specs, the card does support non-power 2. Is it common for non-square textures to be unsupported?

BTW, I'm not talking about my game... I'm desperately trying to get the classic 'Crimson Skies' to run with hardware acceleration on my rig.

You could add

If mycaps.dwTextureCaps_LINE & D3DPTEXTURECAPS_SQUAREONLY Print "Requires Square textures"

to this .
I think it's accurate.

No, I think the last card that didn't support non-square textures was a Voodoo 3 or something. That's why I asked, because it's so unusual it would suggest a driver problem or something.

Lack of support for non-power of two is much, much more common, and I'm surprised that 6600 does actually support it. Assuming the specs you're reading are correct, I would suggest that it's unlikely either of these are your problem, but it could be a driver issue still. I assume you're already updated as much as you can be with Nvidia's drivers?

Are you 100% sure that the game uses NPOT textures or is that just forum talk?
