My rig:

Core 2 Quad Q9650@ 3GHZ
4GB 1600 Corsair DDR3
GTX 280


The game runs mostly smooth with 44-55 FPS on hardcoe @ 1680*1024.
Even with much action on the screen it never drops below 30-35 FPS.

But in 2 levels the framerate drastically dropped under 30 FPS.

1. The harbor ( Pier?) scene in the Lab Rat level. With me standing on top of a building and looking over the pier scene. The FPS go down to 27- 33 FPS.

2. When im storming the CELL camp in "Eye of the Storm".. in the overview scene and when im storming the building to kill lockhart.. 25-27 FPS.

Like i said.. in no other level my framerate dropped under 30 FPS.
Is it only me or has someone similiar experiences?

i have the same issue!

With a SLI gtx 295, on maps with alot of water!

My problem is minor with latest beta Drivers from NVIDIA, 270.51... But with this driver some effects in the game start to flickering, because of the SLI! BUUUUT the FPS increase a little!
