I find that hard to believe since I was having the issue with the demo too before the demo patch and after. I will try it out later though just because I have nothing better to do or try.

The Demo worked fine on my system too. But I'm on steam so there's no downgrading of patches for me.

I got SLI to work (60FPS +) per a previous post in this topic (thanks by the way) but.....
In the beginning of the game the rain effect that is on when they come up out of the water is not there so...
I have never seen this issue before. If I turn off SLI (35-50FPS), the rain is there. Weird. Anyone else notice this?
I don't mind waiting for a update but it just kills me that Nvidia (the way its meant to be played) didn't test this in advance.
Oh well...

Very annoying. My 2x5970's are sitting there, waiting to eat this game up. Guess I'll just finish Dragon Age II and wait for the flickering fix AS WELL as the Directx 11 patch.

I can confirm that reinstalling game and bypassing the update 1.1 works - 5970 owner.

Thanks to skygunner 27 - mate, I owe you a 6 pack - cheers.

Hi Guys,

If you rename the .exe in the games directory it fixes the problem and you can still get some scaling for the game.

So far, the file name should be changed to bioshock.exe for the best results. But the performance is still not as good as when the flickering exists... I can't believe that I'm only getting just over 30fps with a 5970 at 1920x1080. Crytek it is REALLY REALLY REALLY bad that you guys didn't pick this up before the release of the game. Especially with your pedigree and the fact that Crysis is known as a high end game.

It's a god damn crying SHAME that this game is being marred by this, I have been sooo soo excited and hyped for the game and this just sucks balls.

Cheers,
Dave

Edit - If you're reverting to the original version and / or disabling crossfire you're getting 1/2 the performance. While renaming the .exe isn't a perfect solution at least you get SOME scaling... even still it sucks.

Turning off full screen and disabling v-sync worked for me. Playing at 1440x900 with AMD 5970

Have you got FRAPS installed? Because if you do you will notice that you have halved your frame rate by going into windowed mode because window mode doesn't support crossfire (with a 5970 crossfire is always enabled due to the nature of the card).

What res are you playing in and what level of graphics have you got the settings on?

For me, it runs at just at or a little about 30 fps, and it doesn't feel at all smooth to me. In some sections it ramps up to above 60 and it feels INCREDIBLE and I want to play it right now but I'm not getting the experience as I'd like to with the way it is currently.

Not to mention I can't run in 2560x1440 without having the full capabilities of the card...

Crytek need to patch this **** QUICK SMART.

Playing on extreme, 1440x900 resolution windowed mode, average 45 frames

I downloaded the SLI enhancement pack and it runs just fine in SLI now with my GTX260 core 216's, only the first GPU is being %80 used compared to the second doing about %20 GPU usage either way I'm pretty happy with it at this point, running in on my LG LCD 32' TV 1920x1080 very high settings with framerates from 45fps outside to 70fps+ indoors and I use my xbox360 controller as well, crysis 2 picks it up and it plays flawlessly
