A room I visited has latency to my keystrokes in the Text Box. Yes the room uses a hack but not extensively. I've been in larger rooms with no issues. In this particular room the floor does shimmer a lot. I wonder if to much shimmer causes latency? The room owner claims not to have this problem. With 8GB of Ram and a half decent graphics card I don't believe it to be my system. Any feedback would be appreciated. thx.
