so i just upgraded my gtx 1080 today to a gtx 1080 ti today. Im running an i7 6700k @ 4.6 , 8gb @ 3000 mhz.

im only playing Battlefield 1 right now but im dissapointed with the performance. While playing , i observed the usages of the CPU and GPU.

Both clocks for the gtx 1080 and the gtx 1080 ti were @ 2000mhz core clock and @5700 memory clock.

The gtx 1080 would use around 65-70% CPU USAGE and 75-80% GPU USAGE.

the gtx 1080 ti would use around 75%-80 CPU USAGE and 65-70% GPU USAGE.

Theres more stuttering with the gtx 1080 ti and it seems like the same average fps as the gtx 1080.

So basically with the gtx 1080 , my cpu is being used LESS and the gpu is being used MORE while the gtx 1080 ti is using much more CPU power and much LESS GPU power.

is this a bottleneck? or am i doing something wrong here

Also, if you didn't install the latest drivers direct from nVidia, or updated since putting the new card in (I find it helps to just reinstall drivers cleanly after a new card goes in), give that a shot and see if you're usage changes.

Also in nVidia Control Panel, Manage 3D Settings set to Maximum Performance in BF1 under Power Management, it may or may not help, but there's obviously a utilisation issue so just need to try and rule stuff out bit by bit.

Just grabbed screenshots of my settings. I have a 6700k and 1080 Ti as well.

These settings are for a 1440p 144Hz monitor.

Set your framerate limiter to your monitor's refresh rate and the resolution scale such that you generally get your monitor's refresh rate pegged.

I keep mine set so I stay a bit under my refresh rate because I have GSync and it compensates.

Also if you are getting stuttering you are probably hitting your power limit or thermal bin drops. When your clock speed is jumping around to different bins you will experience some stutters.

Console (~ key)
perfoverlay.drawgraph 1

That will show you a graph that tells you what you're being bottlenecked by.

What you want is something like this.


I jumped into a multiplayer game and took the screenshot. The GPU and CPU are virtually perfectly matched, which took me a while to get to.

If you are getting CPU bottle-necked then you'll have to wait for basin falls in order to have any hope of alleviating the problem.

It should be matched? I did clean install and ran the graph. Even with the game set to run on 6 of the 8 threads on my 6700, with my gtx 1080, my cpu and gpu lines dont line up. They are both flat, just cpu is considerably higher. GPU will be like 5 or 6ms. CPU will be 16-17ms on the chart.

If its NOT supposed to be that way, how do you fix it?

and I would say that no, your 6700k is NOT bottlenecking your Ti. Hell, its not until the Ti gets hung up by the 4560.

your i7 6700k should not be bottlenecking your 1080ti ... its virtually a 7700k with better thermals ( no AVX

)

but id be worried about 8gb ram with 1440p

also why don't you update your sig rig? what are your temps etc etc and settings in bios

this should not be happening, you can also tweak stuff in Nv Panel


I noticed in B4 it can be very very sensitive to stuff like.. my audio driver was lagging BF4

so if you have additional audio drivers disable the ones you don't use in device manager also

go into origin and right click the game and set origin to not be running while gaming

I have seen some Threads about the 1080 Ti not performing well with the 6700k but the guys who have the problem only post once at the start of the thread. Then people start coming to help and post replies but the guy who has the problem doesn't write back nothing in all the cases i have seen. Maybe the problem was solved somehow and he just never came back to tell the people that the problem is gone, because maybe the game was patched or new drivers came.

just buy the 1080ti. ihavent played in a while, but i do remember the bottleneck went away when i actually upped the graphics ingame, for example i changed the texture quality to high, used higher anti-aliasing and just higher graphic settings in general and my gtx 1080ti was being used like 85%-100% load, so it definately doesnt bottleneck it. and im sure the new drivers have improved the performance. it couldve been my 8GB of ram also.
If you dont want a bottleneck just make sure you overclock your 6700k and use more than 8gb and overclock the ram also.

I call bs on 6700k necking the 1080 ti. If it was a toms...dont even go back there. Its like Camelot...tis a silly place. Check HardOCP and here. Wont be led astray. A hyperthreaded dual core can run a gtx 1080 just as a 7700k. A basic quad core (7600k) can run a Ti no problems.

The 8gb ram is really worth looking at. Get 16 and call it a day.

Thanks for the quick anwsers

Good to hear that there is no bottleneck, it would be strange if it was on the 6700k which isn't really old. And i have 16gb of RAM so that should do it. Oh and also I wanted to ask you on what resolution are you running? I'm going to be running on 3440x1440 so I guess there will be even less bottlenecking if there was one at the first place.

Thanks again

You will be more than fine. I run at 1440p.

I had the same on 7700k @stock and titan XP @1080p 144hz.. but once i oc'd the cpu to 5.1Ghz the bottleneck gone and my avg was + 180fps all time even on 64player server

if you can push the 6700k more then you will see some improvement

It depends on what games, but your 6700k should do more fine than i5 or lower

By the way I also agreed with the 8GB vs 16GB RAM argument, 16GB RAM nowadays is the sweet spot. 8GB maybe was still ideal 5 years ago, but for now 16GB is the ideal minimum. I've experienced it my self, 8GB RAM playing Hitman + little Browsing quickly make RAM goes insufficient, with 16GB is really help.

There will be NO bottleneck with a 6700k. Not even a 6600k. Just grab 16gb or ram.

You MIGHt see issues if you run games at 1024x768 and super high resolution.

No one does that....2003 ended 15 years ago

how so? most games, like BF1, only use 4 threads unless you go in and build your own user.cfg file to make it use more. Only way I got super smooth BF1 was running it on 6 of the 8 threads for me.

The only game so far that will run across all 8 threads evently is The Division. Lag is another issue, as the way the server-client setup works is terrible...but it uses all cores without some crazy mods.

I put a second 8gb kit on my old 3570k and noticed all my issues that I experienced went away...I really didnt have to build a whole new system...just get 16gb in it. Oh well. It went to a good cause...it replaced my buddies old i7-750 setup. 3570k is mucho updato for him.
