Color resolution in 256 color mode
Hi,
Does anyone now how to determine what is color resolution in 256 color mode under DirectX?
Little explanation:
On TNT, RGB can be set in range 0-255 (8 bits), but on some old Trident it can be set only in range 0-63 (6 bits). This is transparent under DX, of course.
I tried direct approach to palette with assembler out (03c8h, 03c9h) instructions, and it works, but I need to know what is RGB resolution to get correct colors.
I need direct approach to palette because I noticed that Trident card is waiting for an additional vertical blank to change the colors, and since I have some cycling colors in my palette it is bad - I loose full frame rate because of this. With direct changing colors it works fine on both cards, but RGB resolution is a problem.
I'm also curious will the out instructions work on W2000?
(They work on W95/98.)
Also, does anybody know how would it behave on 2 monitor/graphics card system?
Thanks,
Bojan
