Federal's VIS can (and is) vastly improved by taking out a good 50-75% of the stupid "sniper slits" that Tom had created.
I was working on a new Q2WF version of it, but didn't get anything released (was fighting it out with better-equipped spawn rooms for too long) before the mod died off, but once I removed most of those windows it was much easier on the GPU.
