4096x4096 Terrain Texture?

[IzaFly]

Are there any "technical" reasons (besides load times) why not to use terrain textures this size?

I know, for certain textures it would be silly. Like grass. But I'm curious about it to use some nice detailed rock textures.

Older video adapters are limited to lower texture resolutions such as 2048, so by using 4096 you will end up with a significantly larger map file and older systems will never see the 0 mip.
Other than that, and if you are targetting newer hardware only, 4096 is fine.

K thanks. Guess I'll just keep it at 2048 for now.
