Low GPU usage when using SLI in Shadow Of Mordor?

[Samuel Marlow]

hi guys, For some reason when i have SLI enabled in SoM my GPU usage drop significantly from 99 to around 60% usage. and my FPS drops a ton and game becomes a stuttering mess. Now, i have two MSI GTX 980's and this problem does not happen at all when i only have a single GPU active. Any fix for this? it also seems that when i activate SLI it uses more of the VRAM, is this normal for in game? do i have a vram issue on one of my cards? What do you guys think?

Yes i am running the ultra texture pack and running the game at 1440p, but it runs perfectly fine on a single card. But not at all fine when using both. Something wrong??

I dont play SoM but I read a while back that initially the game didn't support sli and then the updates for sli were rubbish.

How is your setup on other games?

hmm.. my setup seems fine running games like crysis 3 and battlefield 4.. but none of those games use over 3.5gb of vram??

vram use depends on the game, game settings and monitor resolution. Usually it would take 4K before a high end game would need over 4gb vram.

i dont really understand why my SLI is causing this though.. the SLI is enabled.. but no idea whats going on.. SoM seems fine for other users with SLI 980's??

It seems you left out the most important piece of information, what CPU do you have?

Is it possible to provide us with a full systems specs? including your OS? We can move on from there.

The issue has been resolved around late 2014 so I think there is something in the works with your system specs.

PSU - Corsair HX1000i

None of that should be holding you back.

What settings? What monitor resolution?

Hi mate, i am using the ultra settings and using the ultra texture pack as well, and my screen is the asus rog swift 1440p 144hz G-Sync monitor. it just seems odd that the game runs totally smooth with a single gpu and not in SLI.. gets really laggy and fps can drop to mid 30's. does SLI use more VRAM than a single setup and maybe thats why? or is it just the game with SLI? i have tried the fixes posted in here but none seem to work.

As I found when searching and as Lutfij has said - there were problems with SLI - back a couple of years. That link I posted is supposed to help if you have such problems.

Is your game up to date?

yep. just checked, game is all up to date. And you post says its how to enable sli in SoM, now both gpu's are having same usage when im playing the game, its just the a lot of the time when playing the usage can drop to 50 - 60% on both cards and fps drop to 30 or 40.. and can stay like that and give me a laggy experience for a good few minutes until it fixes itself.. but then it happens again. lol

As late as November 2014 they were still trying to fix SLI - http://www.dsogaming.com/news/middle-earth-shadow-of-mordor-latest-update-brings-sli-support-adds-new-skins-trials-of-war/

Is it only in Shadow of Mordor that you're having problems with SLI gtx970s? If so, then its the game and/or settings.

I thought I'd revisit the search results and I found this:
http://www.reddit.com/r/pcmasterrace/comments/2tuqd4/i_benchmarked_gtx_970s_in_sli_at_1440p_and_above/

The GTX 970 is a 3.5gb card. It will perform horribly once 3.5gb of Vram is used and is a deal breaker to many high resolution enthusiasts.
However, if you don't run into the Vram cap (1080p, not a AAA fan), then the card is a very strong performer. Extremely well optimized games like Battlefield 4 will run like butter, but I don't see this card holding its value with texture modded games such as Skyrim, Grand Theft Auto, etc.

where did the 970 thing come from? i have 980's haha, and yes, it does seem to be only SoM that i have problems with 😉

 

[i7Baby]

Then its something to do with that game. Looked on the game forum?

980 drivers up to date?
