Hello, i have currently got a secound monitor up and running, and i have started having some informative applications running on it, corsair link, msi afterburner etc. I have also noticed that both my gtx 780 cards are only running at 48 and 52% in Battlefield 1, and i just fired up GTA V and noticed that the cards are running at 40/30%. Have yet to see anything above 65%, which is pretty sad.¨

I have also flashed the cards to skyn3t bios, so they are overclocked, increased the clock so they are at 1Gghz aswell as cranked up the power limit to 150%. Cards are laying around 68-80 degrees with fans at 50% ish.

I have also tried to uinstall the drivers with DDU, but didn't seem to help. Rest of the specs are: 5820k 4.0Ghz, corsair 16GB vengeance running at xmp 2.0, 3200Mhz, msi sli plus motherboard and an EVGA 1000W gold certified. Aswell as the two Gainward phantom cards. I know that SLI is some glitchy shit, but big titles like GTA V and Battlefield should have better support?

Any tricks some of you guys can share? Really hate SLI, but two 780 cards should be good enough for Full HD gaming in decent frames, so sad that i am missing a "whole card" in performance.

Battlefield 1 was a horrendous mess in sli on launch and it's still not working fully.

What's the usage like in GTA V on one GPU if you disable sli?

I seem to remember that GTA V also had CPU bottleneck issues.

Problem is, while sli is still a popular thing for enthusiasts (me included), it's not a high priority for game studios.

I will check and report later, regarding single GPU. Well i have always hated both sli and crossfire, but i usually buy a new GPU when its expensive and then i find a way to good deal a year or two later and of course i buy it.

Update: Uinstalled the drivers with ddu, tried with sli disabled, card ran at 60% average at bf1, fps was like 20-40 less of what is used to be. But cards are still only at 58% and 52%.
