Bottleneck or another issue?

[lookanalien]

So I'm having a bit of an issue... I just purchased an EVGA GTX 1080 Ti FTW3 Hybrid card, and I'm seeing some really bad bottlenecking on my CPU, which is an i7 4790k OC'd to 4.5GHz. In games such as Assassin's Creed Origins and BF1 my CPU usage is hitting 100% while the GPU is averaging about 50-70% while playing at 1440p. I understand this is an older CPU, but I'm seeing benchmark videos on YouTube with the same setup and it looks like their CPU usage is much lower.

I'm thinking of reinstalling Windows, as it's been a while, but does anyone have a suggestion? Maybe I am seeing a bottleneck, and if that's the case I'll look into upgrading.

earleir asked and answer was the cpu will bottleneck the gpu, but not by much.

So likely your issue is something else.

I agree. Running 2600k 4.5 with 1080Ti 1440p 144Hz Ghost Recon and Farcry 5 sits at about 67% CPU and 90s for GPU.

Something else is a miss here. Ghost Recon and Farcry 5 are pretty taxing but don't think they're as cpu intensive as BF1 but close.

You haven't turned off HT?

Have you looked at msi afterburner and displayed all 8 threads to see whats happening there?

Have you always had the 4790k with this Windows install?

Hyperthreading is on according to the BIOS. Showing all 8 thread in afterburner and they appear to be within 5-15% of each other. As far as I can remember I've had the CPU on this install of Windows. Upgraded to this from an i5 3570k(?) at one point while I was on Windows 7, then upgraded the CPU and moved onto Win 10 from there.

Just did a clean install of the GPU drivers through GeForce Experience. Gonna run a few more tests before calling it a night, however there's definitely something weird going on. Came from a 980Ti, but had a 1080 for a week or so as a friend was letting me test it before I decided to buy a 10-series card, then I installed the 1080 Ti.

I did notice an issue when I first booted on the new card - looked like the GPU and drivers weren't playing nice and couldn't access Nvidia control panel, etc. Reinstalled 399.07 and everything looked to be good until I noticed the 'bottleneck'

I read that post before I bought the card, hence the reason I now own one. Thanks for linking that!

Id recommend a fresh install of Windows. People have had trouble going from i5s to i7s and also Ryzen going to a higher core count then previous cpu. Cases where the os wasn't properly utilising the processor.

Suggestion to test a fresh install on another hdd so if it doesn't help you haven't lost anything. Should really do fresh installs after os upgrades if you haven't done so.

Yeah, that what the plan is. Currently backing up my C drive. Once that's done I'm going to perform a clean install of Windows 10. Hopefully that'll fix the issue.
