S!
Along Strike's lines regarding GPU usage. I had the MSI AfterBurner on and the graphs on right side. When over sea or with sea in visibilty range = GPU load skyrocketed. Over land it was a lot lower. Also shadows seem to behave as Strike described, except cockpit shading which works as should.
The patch improved performance a bit, can use native resolution instead of 1650x1080. Some tweaking needed though for the sim to be fully playable. VSync is direly needed, can't stand tearing with TrackIR
My opinion is that dev team could forget adding more stuff before the code is better optimized and bugs cleared.
