Slowdowns on extremely high-end systems on advanced missions (Baltic Breakout)

[jpinard]

I'm starting to wonder if some of the slowdown issues we're having are due to too much RAM or SLI? Currently it makes no sense that a system as powerful as mine could have an issue in the game. Qith the slowdown I"m expewreiencing, it would mean people with an non-OC'ed computer would have the game run at 1 fps in Baltic Breakout. For myself, everything starts smoothly, and when the Russians start to get "actively" involved in this scenario the game starts to stutter so bad it became intolerable. My thought is sometimes with high-end systems and too much RAM a game actually gets worse - this has happened a few times over the years.
So does everyone experience this?

My specs:

* Intel 2700k OC'ed to 5.1 GHz (hyperthreading off)
* Watercooling via Corsair H100.
* 16 Gigs (4 sticks of 4 Gig) Corsair Doninator RAM @ 1866 MHz
* Windows 7 - 64-bit on Corsair SSD Hard Drive.
* Game installed on Western Digital Caviar Black 1.5 TB via Steam.
* 2 Gigabyte Nvidia GTX 680's in SLI.
* Creative Labs X-Fi Fatality Pro

It's because of a tweak we did that just had missiles flying in groups ignore the sensors of all missiles but one. Since they are all much in the same place, we just as well can... That saved a lot of cycles.
