Just wondering if anybody else has been suffering this artifacting in crysis and found a fix.

Its a flicker of distant textures, usually one or two objects in the very far distance might do it, and if I look up at the clouds above me then they do a rave strobe dance for me.

Google has led me to find very little, just that its a crossfire problem (and I have yet to test it with just one card to know for sure) and the few possible solutions have all been a dead end.

I ran into this forum while looking for the RBE program to fix my fan speed, and it seems to be full of other fellow enthusiast that know a lot about this sort of thing so any feedback would be much appreciated.

Im currently 675/1000 on the cards and have tried stock clocks and below to make sure its not an overclocking issue. I also have the fans forced at 50% and have moded them with AS5 so they run nice and cool. Currently I have tried the offical 8.6 cat drivers, and use the 8.7 beta's.

I dont think I will play the game in this state as it will ruin it somewhat, and I dont think a single 4850 if I turn off crossfire will keep me happy with frame rate at 1920x1080 my native res (about 30fps min, 35 average, 50+ max with 1920x1080 all high & some vhigh)

I have a 4850. I was playing Crysis with the 8.6 hotfix drivers, and was getting artifacts, and random crashes. When I uninstalled and put on the 8.5 drivers (ones on the CD, tisk tisk) the artifacts stopped, and I played Crysis with no crashes. It is the new drivers no doubt. While the performance is a bit lower on the older drivers (boo-hoo) they actually work quite well stability wise.

Its the drivers. 8.5 seems to be alot more stable than 8.6. Also avoid that 8.7 beta at all costs, especially with CF. A bad install of that POS can ruin an entire device manager system.

Agreed! 8.7's are no better than the hotfix performance wise and can really screw up some combinations of hardware. And yes, it does work for some people.

I'm using the hotfix drivers and I notice that with my 4870, 4850, or the combination of both, I get artifacts on some of the more plain textures like walls in Crysis. It's only noticable if you are standing right next to the texture (wall) and looking at it.

Hmm I have been using the 8.7betas because somehwere i read they are identical to the hotfix, and the hotfix was amust.

I had to spend all day redoing windows after I flashed my cards, I know it was not a bad flash so unless it was some settings that I messed up I strongly belive it was a driver issue. Oh well I have to reinstall every game now, and if I install crysis again I may downgrade to the 8.5
s to see if its fixed. I know the 8.6's are not working as thats what came on my disk I think.

Strange you say stay away from 8.7 with CF as I thought that was one of the main fixes was fixed and improved CF support.

Im fixed no artifacts at all. Not sure what fixed it as I made several changes at once.

Went from the 8.6's to the offical new 8.7's

Updated the game from stock to 1.2

Went from "full version demo" to "own the game"

Only issue I have now is more detailed and hard to explane and not excluseive to Crysis.

its like scan lines going thru 2d graphis, like in the menu all the text will be jagged but all the 3d graphics are perfect.

I have only seen this happen in crysis DX10 and DMC4 DX10.

It happens not every time but only about 90% of the time when starting the game, and while in the game changing the resolution down and then back up fixes it about 50% of the time. After 2 or 3 times its always fixed.

I have not seen it happen in DX9 yet so its my guess related to DX10 only and probably Crossfire related since the cards alternate frames its almost like its doing some kind of strange interlace thing to the 2d graphics.

I'll have to start a new thread on it and post screens and stuff because I cant find anything on it in google and have no idea how to really explain the problem.

It was the update. With my 2900XT, I got the same damn thing, dissapearing textures and the cloud strobe light, when I updated the game, all that stopped.
