Hello,
The game is experiencing low FPS (almost 50% less) when having DX12 enabled on the F/A 18. Might also be happening in other aircrafts, but this is the one that I have noticed it the most.
Please let me know if you guys are also experiencing this. Vote this up guys and put in tickets to Asobo so this is fixed quickly
My game low fps on every planes when I turn on dx12 
Hope Asobo can fix it
Agreed… VR implementation in DX12 is horrid. It became stuttery and seemed to perform significantly worse. Switrching back to DX11 until the bugs get worked out.
Seemed noticeable to me when using the TACAN key and inputting data. It would slow down a lot.
