Il-2 Sturmovik: Cliffs Of Dover Retail Patch v 1.01.14550

[6BL Bird-Dog]

Hi,
I justrecently crossfired my system (Specs below)and on the first try I found the black death was more fluid than I had ever seen it before.Free flight over London was the best I ever saw too.This was running on Retail Patch v 1.01.14550 .
Because of the closeness of my two graphics cards the top one is getting hot not being able to draw ebough air through the fan due to the second cards pcb being 12mm from the intake .Having the rest of the system watercooled I have ordered two full size Waterblocks which will irradicate the problem.
On the release of the 1.01.14588 patch I now find all is back to a studdery mess so I cleared every trace of COD off the system and did a clean instal.
Regardless of what settings I have set the game or the Graphics cards to it
ramains studdery.Seems like the little patch has messed something up.
