It didn’t restore all my performance lost by SU3, let alone the 15 fps WU3 stole, but I’m able to get 25-30 fps pretty regularly now, where I was getting 30-35 prior to SU3.
I still get some bad dips into the teens at times in busy areas, and I still can’t fly over London to check out the UK update. Tried taking off from London City on the weekend and I was sitting there at 2 fps.
But all in all, I can fly again with mostly acceptable levels of performance.
Oddly, I’m now able to run at all Ultra without any effect on my frame rate, whereas since the VR update in December, I had to run at a mix of med / high in order to maintain my 40+ fps (was all ultra prior to that). Whether I run at med/high or Ultra, I see neither an increase or decrease in my frames. The only thing that seems to have any effect on that is my terrain LOD.
