Trying to isolate a recent issue. I am waiting for my forum account to be approved over at A2A, has anybody had any issues with FPS decreasing about -10 at all airports? I installed this great product and seem to be now runing anywhere for 8-14 fps when i ran 24fps on avg. I cant seem to find any post about fps and 3d lights. The only other change was the latest nvidia drivers, i then went back to the previous driver. The strange thing is that I can be sitting at KLGA at night with 100% AI, and run 8-14 fps and then sit at LIMC (2am) and still only hit 8-14fps with a very quiet airport. That makes me think its not 3d lights.PaxBrad

My experience may be similar. I installed Shockwave 3D Lights on my PMDG 737 and (1) can't see them!! and (2)my framerates are very low inducing stutters when on final and taxiing. I do not have any frame reduction with default planes with shockwave installed or with LevelD 767 (without shockwave installed).So the issue could be shockwave 3D Lights or simply PMDG 737 being frame rate hungry.Hope others jump in here to help us.Bill
