    Hey,

    Suppose I wanted to make RenderTextures more-or-less a requirement to run a web game that is targeting wide distribution and low system requirements. With DirectX support, does this sound sane? Does it matter if they are POT or not?

    I'm just wondering roughly how many computers wouldn't be running the game properly due to hardware limitations, buggy drivers, whatever.

    Thanks,
    -Jon

    On DirectX they are reliable. In some cases you have to watch out for out-of-VRAM issues (e.g. 32MB cards). On 16MB (or less) VRAM cards we disable render textures altogether; too low VRAM size for any practical reasons.

    In Unity 2.0.2 on Intel 845/865 cards render textures on drivers older than January 2004 will be clamped to 512 pixels in size. That's about it.

    Power of two render textures are probably supported by more old crappy cards... I don't quite remember.
