My problem this time: the game turns into a slide show after I go to desktop and back to game. It started couple a months ago when my old gtx 8800 was at its final stage. Bought a gtx 260 and have had the problem every now and then when playing the regular 1946. Now the ultra pack mod is really sensitive, sometimes I have to attempt repeatedly before the game runs smooth.

Any ideas?

processor intel core duo e6600 2,4 ghz
mobo asus pb5
2 G ram
gtx 260

I get the same thing, with the same graphics card. The only thing I can think of is to try new dlls? I try my hardest not to Alt+Tab out & Alt+Tab back in.

CPU: Core 2 Duo E8400 @ 3.6GHz
Board: Gigabyte X38-DS5
RAM: Corsair 4Gb PC8500 DDR2-SDRAM
Gfx: Leadtek GTX260 896Mb

I use an ATI but Squog might be on to something with the DLL's. Go to AAA and hit the search button and search for 5_DLLs, good luck..

I've had them 70 km visibility DLLs for quite a long time now, is that what you are talking about?

Forgot to mention that my graphic card drivers are the 182.08 if that makes any difference.

Nvidia dirver Version 185.85 solves this issue.
