I still have an Viper330 with RIVA128 chip, and this chip doesn’t have automatic transparancy on textures. This means that when I use a texture that has a “light round” in the middle and black all around, the black stays black and overwrites the picture in the background. I have to create an alpha channel myself and only then will the card display this right.
Newer cards don’t have this, so a lot of games don’t display right on my card.
Now for the question:
Is there any way I can lookup if the video cards does or does not support this feature, and when it doesn’t, only then I have to create the alpha channel myself, saving memory for people who have automatic transparancy.
