Thanks, so it would be a GTX770 OC !

To ask before i by a new Card, - at the moment my GTX760 2GB has not enought free VRAM if a use a AddOn Airport like FSDT or FlyTampa. I look for a good 770 with 4GB or 780 with 3GB - but I think 3Gb may also be too little free momory ?!?!

I think it´s better to use a 4GB graphics card. After fresh installation P3D use 1.6 GB graphics memory. I disable fog, shadow and tessellation, use lower settings - P3D needs 1.4GB.

One thing that has worked for other uses when this happens is to go in and change the global texture resolution to something else and then change it back....

Same here - will also enable volumetric fog!
