You may have a point. I am having worse/same performance and I do have a GTX460. I wonder if there actually is a pattern with nvidia cards?

Affected by this bug so far (already raised an issue in the Bugtracker, go vote for it :P ) spit1a and spit2a.

Getting the same fps using.

5870 1GB
AMd 955 @3.6
4GB ddr 1600mhz ram.

I have to turn almost everything low/off to keep the GPU memory under 1GB. Is this normal for everyone else ?

Negative, my setup is ATI with both stutters and FPS drop.

i could actually up my settings whilst maintaining roughly the same amount of fps.
Are you using the new Catalyst 12.4 by any chance, as that already gave a slight performance increase (mainly reduced stuttering a bit and minimum fps were very slightly higher, well within measuring accuracy).

YES I was downloading 12.4 before testing! The only big Problem is launcher crash! That is what really keeps me from flying! Because there is no point in beginning a mission right now!

Interesting, after I disabled the crossfire my FPS doubled and stutters significantly diminished.

New problem became on/off blinking of exterior plane texture. Plane textures would disappear and you can see the pilot inside the plane.

Definite crossfire issues.

Not at all! But have to say that my 5870 1 GB did not perform good in Cliffs of Dover at all! And i think the cause is it has "only" 1GB ram. Maybe you should try the 12.4 Driver.

You run WinXP or Windows 7 on your system?

ATI CrossFire Users - see the following post for a possible solution:

I would have to go with worse. Not that i would know or anything, i cant even start the game.

Used every single trick in the book when installing to no avail, get the black screen with the "gunsight", pc working 20-25 sec and then, bam, im back in steam. I verify integrity so it reverts back to previous version, and everything is fine again

Guess i have to wait for the official patch.
