Of course I don't know how demanding any of this would be or if it would even be possible, but i...

Try changing the moving map display to checklist mode (button in bottom-right), that brings the frames right up for me.

<t>I too am getting poorer performance in 2.3 than in 2.2 - lots of stuttering (though my FPS remains about the same), even with all weather cleared and settings turned down.<br/> <br/> <br/> <br/> One thing I have noticed is that my GPU (NVIDIA GeForce GTX 760 w/ 3 GB GDDR5) is only running at arou...
