Topic: Shadow artifacts on Linux

Hi,
I have some problem with Maratis when enabling dynamic shadows using the
open source ati (radeon) video driver on Linux.

Could this possible be fixed in shader code?
It would be nice if open source driver(s) could be fully supported by Maratis too.

Re: Shadow artifacts on Linux

Hi,
thanks for reporting,

it is likely that this driver doesn't support depth textures,
you should report to the mesa team that the "GL_DEPTH_COMPONENT" doesn't seem to work properly with your configuration.

I'm also using a mesa driver on linux, but with a nvidia card, and the shadows are working properly.
