I've found unlimited frames has worked best for me ever since 2.0, doesnt half gobble up my gpu vram though, I still maintain that 2Gb is the bare minimum for P3D!
These new cloud shadows are a huge perf killer for me even on the lowest setting, also blurries seem quite bad out of box. This is a fresh install from the patch with only orbx global+vector installed. I've still yet to finish downloading the full 2.2 install so ill have another crack at reinstalling from that to see if it helps
