Can't get 144FPS in Diablo 3 with Top Specs

[hoofhearted4]

Good Morning Nexus friends! it feels like it's been a couple of years since I posted here. I have this topic going on the Blizzard and Diablo forums as well, but of course I had to try my friends here as well.

So i recently built a new PC and i can't get 144fps with it? (actually this is cool in itself because i posted here something like 5 years ago when I was getting ready to build my previous and first ever system!)

i7-7700k @4.5Ghz

Gigabyte GTX 1080

16GB DDR4 RAM 3200Mhz

Windows 10 x64

Gigabyte z270 k5 Board

Dell S2716DG G-Sync 1440p 144Hz 1ms

i get anywhere between 60-80fps. occasionally getting higher. often getting lower. The VERY first time i booted up my system and played the game i was getting 130fps and above rarely dipping. but since, i get the aforementioned fps. I've removed all old drivers from my system (my OS is from my previous build), reinstalled D3, reinstalled my graphics drivers. D3 is installed on an SSD. about the only thing I haven't done is do a clean install of Windows.

Other games get 144Hz, and my benchmarks are all where they should be, and stress tests are all clean, so i know its not a faulty card/CPU. because i do get over 60, i know its not vSync enabled in game, and in the menu i get 144.

Here is the kicker though. My friend has a nearly identical build to mine, and he gets 144 no problem (his specs listed below). the only difference i can think of is he is plugged into the internet, where i have to use WiFi. would this really hinder FPS? my latency is no difference then his.

Can anyone think of what could be going on? i would normally chaulk it up to bad optimization, but he's getting the desired FPS. Thanks for your help guys.

whats your clock on the 1080?

 

also what temps do you set at?

[hoofhearted4]

i think the card is at 1936Mhz.

 

I wasnt monitoring during the game, but it never broke 70 during FurMark. so i don't think it's a throttling issue or anything.

 

Also for what it's worth, i got the card a week after I built the system, i had a 980Ti before, and was getting the same performance.

 

Something else I didn't mention is the FPS doesn't go up if I change the settings or drop it to 1080p. i get exactly the same frames.

 

Thanks!

I had this same issue after upgrading my 780 to a 980, I reinstalled windows.

 

But You should just have to reinstall the drivers, boot into safe mode, uninstall all video drivers, reboot, then install the newest ones.

 

do not use geforce experience to do this.

i might just reinstall windows. considering all of my hardware has changed it wouldnt hurt to do so anyways.

 

i did uninstall all old drivers and reinstalled what i needed, but not through safe mode. there's no drivers from my old system.

re-installing the OS fixed it.
