SLI Flicker

I started a new game up today not having played it in roughly a year and i'm being plagued by terrain flicker. I know that this problem was caused when running SLI but I thought it was fixed several patches ago.

I went through all the 'fixes' I needed to do back then such as setting power management to pref max perf in Nvd Cont, not having Origin overlay on etc ( I'm not willing to turn off SLI in order to 'fix it' ) but it's made no difference. It's not small areas flickering either, it's fairly large ones, larger than what I remember anyway.

I'm currently in Haven where if I remember the worst of it happened, but it's driving me insane to the point I may just quit playing it altogether if it can't be stopped. So my question is, is this still a thing even though it was supposedly fixed many patches ago and are there any other solutions in order to fix it now?.

Specs are:

2 x 980ti

i7 5820k OC'd 4.5

16Gig RAM

and playing in 3440x1440

Just to rule it out i've checked all hardware and everything is running just fine.

It might be worthwhile trying the following even though it is not for the exact same issue: http://answers.ea.com/t5/Dragon-Age-Inquisition/SLI-camera-panning-stutter-fix/m-p/4624242#M56214

Let us know either way if this works for you please.

please read the original post in the sticky :

ongoing investigation

The flicker is caused by z-fighting

z-fighting is caused from the alternate frame rendering, where the "flicker" is generated by the

out of sync timing of the frames generated by the multiple cards.

try changing the SLI rendering format, through the 3D settings in the Nvidia Control panel.

AFR 1, AFR 2, (AFR= Alternate Frame Rendering).

The flickering issue was never completely fixed, AFAIK.

The only way to truly alleviate the flickering issue is to disable SLI, while playing this game.

Hi, thanks both of you for your suggestions. Nothing unfortunately worked, however I when I was going through some in game settings I noticed an error on my part which I didn't think would be a contributing factor to the flicker but rectified anyway. I realised that when switching out my shader profile for a new one, that at some point when I last played I must have taken them out completely and turned MSAA and Post Processing back on but forgot to turn them off again when adding the shaders back in.

Turning them off and then running around Haven for 30 minutes and so far I haven't seen a single instance of terrain flicker, which considering I couldn't walk more than two steps before without seeing it, is something. Whether that was what was causing it I don't know and i'm fully expecting it to rear it's head again but so far, it seems to be gone.
