I have 4870x2. To solve the flicker problem I've installed RadeonPro and use Bioshock profile. But my fps is really low. Sometimes it goes bellow 25 (1600x1050, Extreme). Any ideas on how i could get my fps higher by tweaking in my radenpro profile? I still want to run this game in extreme. I've heard you could disable Aero, any other things i could enable/disable?

I'll try this thanks.

Does it reduce image quality at all? Because if the work-around is to compromise anything I will just wait for the patch that fixes it.

Not that I know of, the water will still flicker when looking at it from above sometimes, but other than that it is a fix, not a compromise.

Actually, I'm kind of annoyed I've been spending 5 days trying to get this POS to work.

I'm going to go play some Far Cry 2 which Ubisoft actually patched to fully support three-screen resolutions. The HUD displays on the center monitor and isn't stretched out to the sides like this POS console port. Also It has that sand-box feel that I won't be getting in this game.

Wake me up when Crytek does.

Has anyone tried my method?

Too busy playing Far Cry 2. I'll check back when this game is fixed. I'm not going to waste my time soing crytek's work.

I wish one of the crytek mods would post an update about this particular issue and make it sticky, so we don't have to search for potential new fixes or eta's or updates about when we'll be able to play the game.

It's been 5 days now and I have no idea if this issue is being worked at or not. People keep says "Crytek is busy fixing it" but how do you know this? I don't see anything official. People also say "Please be patient while they fix it" but seriously what kind of timeframe are we looking at here, and again how do you know this?

I dont give a rat's arse about DX11 or sandbox mode, I just want to play the effin' single player campaign without getting an eye bleed.

I've tried all the compromises and fixes and workarounds listed in this thread and these forums, nothing really works for my setup (HD5970 2GB) - but it's getting frustrating wasting an hour each day going through all the threads trying to find updates or new fixes.

I'm sorry for being so unreasonable as to demand basic gameplay from a retail game. Why is it normal these days that new games don't work immediately but only after a few weeks and patches? Why do people get flamed for complained the game doesn't work out-of-the-box? Is it really THAT unreasonable to demand that?

I kind of solved it, tho its not a real solution and i hope Crytek is working on it, i just raised the brightness level in the game and it's not a bad patch, not flickering anymore and playing with CFX.

yea tried this too, it makes the flicker go away until I encounter a bright light source or look at the sky, then it's back

Didn't work for my Tri-SLI flicker. Though it's not the full-screen flicker others report.

Also, SLI bugs out my motion blur, it's alot less smooth and more like the ghosting of a 45ms LCD.

That's strange... Sorta what mine does when I don't have the post processing command removed from autoexec.cfg

I would try turning on (or off) v-sync as well as setting both r_HDRBloomMul & r_HDRBrightLevel to 0 and see what happens... Also did you install the latest SLI updates from Nvidia?

Yeah I've had every driver in recent memory on here as well as all the SLI profiles and tried some different stuff with nvidia inspector's advanced tweaks.

If I play with NO sli everythings great, enable it and the flickers appear and the motion-blur turns strange-looking.

Neither the flicker nor the broken motion-blur were in the demo.

Workaround for the AMD CrossFire that works for me:

Rename the Crysis2.exe to Cry2.exe (in the bin32 folder in the installed directory) and then run the executable with the new name.

What I think is going wrong:
AMD detect Crysis2.exe and apply some optimisations in the driver. These optimisations work for the demo, but the release .exe is different and the optimisations break the rendering on CrossFire.

However, I cannot guarantee this will work for everyone. AMD should be working on a driver/profile fix as I type.

Yeah, true, but at least it is somehow playable even with the insane brightness level.

I'm just playing MP right now, I wont try the SP again till AMD or Crytek solve this thing, still make me angry the fact that no one at Crytek tried the game with a CFX/SLI system... (of course they did but, ?why solving it before coming out? they knew perfectly that we would run buy the game).

Tried it. Lots of missing textures for me...nifty little wallhack, tho

hi Cry-Adam

Lot of people here on this forum and other forums too, they have one neccesary question. Where is DX11 support for PC gamer's? I didn't find topic with your answer. Could you please reply and tell us when will be?
Thanks a lot

Any news on when we get a crossfire fix

come on crytek give us some crumbs...a daily update or something. what's the wall of silence for.

They are waiting for the executives in charge of the game to get back from their weekend so they can ask them if the game is selling well enough to patch or if they should just let cut their losses now.

when the **** are they going to fix this?

If this goes one week without at least an acknowledgement or sticky about this issue, I'm DONE with Crytek!

Well to be fair, this thread is linked in the sticky about PC issues.

They don't actually say they know WTF is wrong with the game or provide an ETA though.

Oh and besides the flickering that I see with SLI: http://www.youtube.com/watch?v=DjpN5HoX8xA

There's also an issue where SLI completely breaks the Motion -Blur effect.

Here's normal Motion blur : http://s4.postimage.org/61uc406u7/2011_03_27_00003.jpg

Here's the motion blur produced with SLI enabled (note how it's just a ghosty afterimage) http://s4.postimage.org/61uaggucf/2011_03_27_00001.jpg
