Actually i fly DX10 only with small GA Aircrafts. When i would fly with PMDG(737, 747...) i have a performance loose. Thats because of the contrails. PMDG 747 with their own contrails and 737/777 with VFX Contrails. All of them are hitting the system hard under DX10. Is there any chance to fly those beasts in DX10 without that big lost in performance and visuality? I have set to lights effect only. No heavy antialiasing settings(makes no different from 2x to 4x Grid) Whitout VC Shadow it is slight better but an overall lost in fps about -10fps.
For some reason i have no probs with Majestic Dash and VFX.
