"Works great with VR! I recommend it for the better turbulence and wind depiction alone, among other nice features!"
"I'm using this very good, impact on fps is little and is caused mainly by the quandidate of projected clouds, I felt much impact with the high AA, with fxaa not had so much.
Comes out of NOAA for him the difference is absurd now seems like a real sky, pity that still refreshes the clouds sharply, but in relation to reality is worth very much.
Only problem is that NOAA I did the compatibility for AviTab in ASXP does not have, but how you can get the METAR by the Radio that compensates.
ASXP has an interesting API, if @Folko could make an app in Avitab to configure ASXP it would be perfect".
