I’ve been playing with 4.33 since its release and have been greatly enjoying this version. I seem to have a problem with massive FPS loss when accessing the TGP and MAV WPN screens. I normally get 85-90 FPS when flying the stock KTO campaign. Whenever I access the TGP or Maverick weapon screens my FPS will drop to a constant 15-25 FPS. I have spoken with others in my group and no one else seems to have this problem. Between 6 people all of them reported a loss of about 5-10 FPS when using the TGP, this can be expected. I find myself having trouble employing weapons when using the TGP. This problem persists for both AA and AG TGP use. I am running a AMD Radeon R9 390 Series GPU and an Intel Core i5 3570K CPU. Running BMS 4.33 64 bit. I have experimented with many different graphics setting and nothing has made a dent in this FPS loss. I really like to the new features for the TGP and I would really appreciate any suggestions to help fix this issue.
Check my rig…very similar and I have the same issues; however, I’m not getting the 85-90 FPS you are at the top end. I’m using FRAPS to report FPS.

There are many suggestions, and other than turning off shaders, etc., I see no real improvement overall, and nothing that brings the TGP back to real time.
