same problem. on some maps its badder than others. On granary pro for example there are lots of props which are black including the crates at mid but on normal granary its fine.
edit: I don't know whether it was a tf2 update or updating my cfg that caused this, but its one reason why github and properly committing your changes would be useful comanglia ;)
try changing mat_mipmaptextures it should work
