Hello my computer has been down a month or so from redoing my loop. I use to run 1070 sli with a 5930k at 4.5 and I switched to 1080 ti sli and cant figure outs what’s going on. I can go to a empty server on bf1 or bf4 and never have drops below 170 fps running ultra 1440p with Taa turned off and post processing turned off the rest on ultra. When I join a full server my frames drop to like 115 in bf1 and 135 in bf4.

I have updated drivers with DDU I have reinstalled windows and tried config files to no avail, nothing seems to work and I use to never have these problems with 1070 sli.

I have tried each card individually in game and in fire strike both cards run well in fire strike but even running s single card in game my usage is only 75 to 80 % when in sli in bf1 both cards are using 42 to 50% my fire strike score is 31,853 2 highest for 2 1080 ti and a 5930k.

I am wondering if this is a game problem or something to do with Windows I have read since the Windows update that some people are having alot of performance loss.

Thanks for any input!

I have read many people having issues with it in sli. I knew you said you turned TAA off when I originally read your post. Somehow I had a thought dump and ended up posting it anyway.

I understand it isn’t the best but what has happened from a month or 2 ago I use to run this game flawless with 1070 sli and not to mention what is going on in bf4 my frames are dropping in it also and what I don’t understand is I can go to empty server and everything is fine get on full servers and the fps stars to drop a significant amount from what I use to see.

Not using same drivers I have tried 3 different one no GeForce exp and game bar is off. I don’t even think it’s possible for me to remember the driver lol I don’t change much if it works and that could be pretty far back on the dates.
 
What is your cpu usage on each core when these drops happen? Do any cores get close to 100% usage?

My thought is sli does carry a cpu overhead. With the stronger gpu’s and higher FPS the limitations of the cpu are being exposed. Multiplayer games like BF1 & BF4 have significantly more cpu load when there are more players so my theory would also explain why you see such a difference in empty vs full servers.
