SLI headaches. (Postprocessing messed up)

Post » Wed Nov 10, 2010 7:40 am

Here's the rundown for my situation.

I'm running this:

Gigabyte x58A-UD9 motherboard; i7 980x CPU; 12gb 3channel ddr3 2000cas 9 (3x4gb); 3x gtx480 SLI; 1x gts450 (physX and 4th display);1500W silverstone Strider PSU;Areca 1880i Raid adapter

(dxdiag https://docs.google.com/document/pub?id=1vf3MnF_QkaJmtanC8ZeqEEs_iV76xeYxj0pLXuzozgw )

I have 2 issues mainly. Both seem related to the way that the SLI is handling the post-processing, like it's not sharing the rendering properly.

The motion-Blur is an easy spot to see this in action. Here's 2 SS, one with SLI disabled and the second with it enabled. Note how odd the effect is with SLI.

Blur looking normal, SLI disabled

Blur looking like a trailing ghost-image with SLI enabled. (not nice)

The second issue involves shadows flickering on and off as my view moves. Here's a youtube vid showing it. (youtube conversion to 30 fps makes it appear a bit less flickery)

Now I have tried every Nvidia driver in existance from the last 6 months as well as all the tweaks and tips in the thread in the forums. The only thing that fixes it is disabling my SLI which is not an option if I want to play this at 5760x1080 or in 3dVision.

I also tried dedicating one of the 480's to physX so the driver ran 2 way SLI instead of 3, and it did this :)

I'd rather not remove any effects to work-around. Just wondering if they're aware of this and are fixing it.

I can wait to play the game with full graphics. I'll mess around with nvidia inspector later maybe, but im not convinced it's a driver issue, the demo worked fine.

Crytek, could you at least give us a hint that you know about this bug and have a fix in the works? Nvidia says it's not a driver issue but that we need to wait for you guys and EA to fix it. But EA/Crytek have been bogglingly silent on this issue which now has a 70 page thread.

Have you tried the EVGA SLI Enhancement? I had issues at release with my 2 580's but after installing the Enhancement - no more issues and Afterburner shows both GPU's at 99% while playing.

Whatever you guys are about to post I should try. I've tried it.

THe only thing that stops the glitches is to play with out SLI. And the other "work-arounds" all compromise the quality of my experience, so no thanks.
