Very low FPS on 980Ti SLI

Not sure if anyone can help me here but I've just started having this very weird issue that came on a few days ago.

Basically, I run my client with everything set to high on a 4k monitor with 2 980Ti's set up on SLI, which for the past month has caused me zero issues. Eve has been wonderful to play and I have suffered no FPS drop at all. I achieved a constant 60 FPS regardless.

Two days ago this all changed as my FPS went from 60 to 10 (at best) with no reason at all. My computer simply will not run Eve comfortably. If I disable AA I will probably get to the 25FPS mark which is an improvement but still not the 60 I was having before and moving from DX12 to 9 has no baring. The weird thing here is that if I disable SLI, everything goes to how it should be! (everything on max, including AA and getting that 60FPS again).

Now I don't believe this to be a hardware issue but more software or driver related. I've swapped the GPU's around, changed the cables, rolled back the drivers and now reverted back to the most up to date driver set for the GPU's and the BIOS, changed the bridge, installed eve on a separate HDD, all to no avail.

The Specs for my machine are...

- 1000w Corsair PSU
- Asus Gene Maximus VIII MOBO
- 2x Nvidia GTX 980Ti SC (In SLI)
- Skylake i7 (overclocked to 4.5) with a Corsair H100gt liquid cooler.
- DDR4 32GB Corsair Dominator Platinum
- WD Blue 4TB Hybrid

The computer is 1 month old and everything was bought new.



Anyone with a similar issue here?

Thanks.

Which driver did you roll back to? Do you get this problem in any other games?

Hi there,

Currently I'm on the latest driver which is 354.72. I rolled back to 364.51. I should note that this machine has been on nothing but Windows 10.

I only have one other game at the moment and that's world of warships. The issue isn't present on this game.

Thankyou.

Anyone else guys? It's kind of bugging me as to why this isn't working now.

Thanks.

It wouldn't be the first time I've seen SLI/Crossfire being very hit-or-miss in terms of performance. MWO, for another example, still has artifacting and other image bugs associated with running SLI from what I hear. It's why I usually tell people to first consider buying a really good card that can stand on it's own rather than buying two, even if either are really good.

Fortunately, your system obviously hardly needs SLI as you already noted. I'm not the most tech savvy, but is there a way to allow Eve to run on one card even if you later wish to run something else in SLI, or is some tedious every-time-you-run-this-you-must-do-that sort of process to flip back and forth?

Something else you could try is simply rolling back to yet an older driver than the one you already rolled back to just on the chance it's an issue that was introduced more than one driver back but not actually solved yet.

"Tomahawks?"

"----in' A, right?"

"Trouble is, those things cost like a million and a half each."

"----, you pay me half that and I'll hump in some c4 and blow the ---- out of it my own damn self."

Yeah there is. Basically you set a rule up for when you launch the launcher.exe that the game only renders using the one GPU. That's working like a charm at the moment. The system still recognises that it's in SLI mode too.

Thanks.
