Hello,

Does anyone know if multitexturing affects older graphics cards performance in any other ways than adding to the "fillrate" factor?

Would it be any benefit to have an option to disable multitexturing in the game to increase performance even though it greadly reduces the appearance?

Finally, can it be said that pretty much every graphic card can handle 2 multitextures?

Thanks in advance =)

Yep. Some blend modes are actually slower. Depends largely on the card.

Then, the more you multitexture, the slower it becomes.

However doing 2 multitextures is usually considered pretty quick. It's all comparitive.

I'm only using blend mode "add" which I presume should be quite quick.

Problem is that black objects with a spherical, added environment map locks great if multitexturing is enabled where as the blocks nearly become invisible if multitexturing is switched off =) Which is not very good.
