Well, it wasn't for nothing, plenty more optimization done today, but unfortunately as per usual, the patch asobo pushed yesterday is causing this issue, unsure if you've experienced this yet, but SU 10 is completely unstable, here is a post of what is going on, you will not see it unless you are in dev mode and check both debug options for collision viewing https://forums.flightsimulator.com/t/dx12-issues-weird-graphics-glitches-stutters-in-panning/529129/135
I can only recommend waiting for asobo to fish this, which how bad it is, may actually be quick.
