We have got some news about a new tool which can assist you in setting some new brilliant performance tweaks for FSX.  It seems that these new settings in fsx.cfg will improove the frame rates of your flightsimulator very much; especially if you are using such powerful addons like openVFR POI.  Anyway, we hope that we can launch a frame optimized version of our addon in the near future as well. So things becoming better soon.  ;-]
