I'm getting a lot of Z-fighting on textures with the 64 bit client. Is there some setting I should uncheck somewhere so certain textures aren't getting displayed twice? I suspect I only notice it when two different textures are on the same surface, or textures of different resolutions.
I also haven't done a fresh client reinstall in a long time so I don't know if there's some old textures that are still being used behind the new ones.
