I have discovered that some video cards support paletted textures and some do not. I know how to detect that and handle it appropriately. But I have also discovered that some video cards which support paletted textures will only support one palette while others will support a great number. How do I detect the maximum number of palettes supported by a video chipset?

I''m not aware of any limit on the number of palettes. If you''ve found one it is likely a driver bug, which would hardly be surprising considering how poorly supported paletted textures are. They are so rarely (and poorly) supported that I wouldn''t recommend wasting your time with them.

Normally, I''d just stick with truecolor images but I''m developing a viewing application for a pre-existing format which uses paletted images. I can simulate palette support for video cards which don''t have palettes but that takes 4 times the amount of video memory and we''re talking about files that often have 50Mb of texture data in index-paletted form. So I''m developing the display as a dual-system: palettes when available, truecolor when palettes are not supported.
