So, back home and everything is still running great. Alt-Tab gives me about 5 seconds of white screen, 3 seconds of 0 FPS, then up to 45 then to 60 in less than a second.
It seems to me that somehow the update caused my settings to run higher than what was registered from my personal settings. In turning them down, then exiting, and turning back up to normal, it 'reset' the settings to where they were. Honestly, I'm not a coder so I can't say if that's what happened, but it's really weird it corrected itself.
I had a squaddie who was getting 2FPS do the same thing, and is now up to 25FPS, still not great, but a marked improvement.
Turn off all graphics, and turn down shadow to 128.
Load Game, then Exit
Reload Graphics back to previous settings (For me 512 w/ Bump Map, Detailed Terrain and Water)
I was back to even 60.
I'm about to try a few flights, I'll update if there are any spikes.
[EDIT] Everything seems fine so far, same map as ealier, so I'm not sure if it's a map issue, but if this fixed it than awesome.
[EDIT 2] Played all night, even flew a few 262 sorties, no jitters, no drops.
