It's working fine for me. And for some reason, I get about a 40% increase in frame rate when Voxel terrain is active. TT has always run my GPU's at half clock speed for some reason (according to OSD from either afterburner, or Corsair Link anyways), but now with that one mod active it shows (and feels) full throttle. There might be some valuable info in there somewhere.
