Pre SU12 I’ve been using DX12 constantly. Looking around the cockpit etc yielded smooth motion and good fps.
Post SU12 I’ve been getting okay’ish performance… I immediately noticed lower fps and stutters when looking around the cockpit. Main thread was going crazy (into the red a lot). At cruise, where I’d usually get 45 to 55 fps, I was getting 25 to 35. GPU utilization was at 80%, then 8%, then 66%, then 30%… you get the point. I was hinted to check this as I could hear the GPU fans speeding up and slowing down constantly, where as before they would be steady.
I switched to DX11 and performance seems to have immediately increased, to my surprise. GPU utilization is steady, fan’s as well.
I have yet to do a flight, but thus far it’s promising.
Is anyone experiencing the same?
Has Asobo mucked around with DX12?
Is this worthy submitting a support ticket?
