gtx 1080ti cap at 120 fps at 1080p a cross all games

[Jun Wei Goh]

hi guy .Can anyone explain to me why pretty much all games i run all will be cap at 120 fps(v-sync is off) .The gpu usage around at 40-60% only but the cpu is about 50-60% usage only. But when i switch to 4k the gpu is able to reach 100% and cpu usage also somewhat the same as in 1080p. My cpu is i7-4790k at 4.4GHz with a msi gtx 1080ti gaming x

This is normal. The GPU won't boost or go higher than it needs to. When you up the resolution then it will start boosting and using more power.

G-Sync, single core thread usage high?

- RAM

- Windows Version 

- GPU driver Version

- Monitor

- Power settings (windows+nvidia control panel)

- some game titles

- (maybe) PSU

- CPU temps

 

in general full pc-specs would be helpful.

no g-sync cpu core usage all balance

window 10 latest version

driver 390.77

cpu temp around 70c max within the safe range

power setting prefer max performance 

window is samsung ssd performance

Well if none of your CPU cores are getting close to 100% usage and the same is true for your 1080ti then I'd say that the problem is either software or driver. Given that it happens to all of your games at 1080p then I'd say that your driver is the only common factor.

What happens if you play Overwatch at the lowest settings at 1280*720?

pretty much the same thing.I guess maybe at 4k all gpu power will then kick in

windows:

have you disabled "Game DVR"?

are you using the build in "gaming Mode"?

 

please disable both and try the following (windows registry):

 

go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games and change the following registry values:

“GPU Priority” change its values to 8 for gaming.
“Priority” set to 6 for gaming.

set, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile SystemResponsiveness to 0

 

then restart.

 

Please report back if this makes any change.

ok sorry for the late reply been out for a while yes i done that still the same result

are you using FastSync? Well something must be wrong, so i would start to try different drivers and reinstall windows when you cant find a solution elsewhere. From googling i found different people with similar problems but most of the time it either was core parking or any other power saving feature that caused the problem.

You'll not see that. If the game is single threaded and it would run on one core at 100% you are not be able to see that. Because the OS is evenly scheduling this single thread on all cores.

On a dual core you would see around 50% on both cores even though it is maxed out.

The OS dictates what the OS does. Why would it magically convert a single threaded game to a multi-threaded one?

In fact, take a look how a well known single-threaded game looks.

I'd also like to mention that I wasn't specifically talking about a game being single threaded, but it being maxed out on one particular thread whilst the others are not. This has a similar effect.

Never said that.

Again, a single thread can be scheduled on multiple cores thus you wont the one core maxed out.

Is this not in contradiction to the image in my post?

No, that is only one example. ProcessorAffinity could be set by the game while other games do not.

What you're describing sounds more like a software issue as I mentioned above. If everything is getting loaded into a single thread that bounces between hardware threads then it's a software problem. If the processor affinity was not set in an application that ran across multiple threads then you would likely see high CPU thread usage across the board which would signal a potential bottleneck anyways. I get where you're coming from but I misinterpreted your initial response of "you'll not see that" since it should have read as "you may not see that".

nope no fast sync or g sync .All driver pretty much the same thing no not going to reinstall window for this.I doubt is driver cause at 4k i am able to hit full gpu usage guess gtx 1080ti likes 4k

No it is not an issue. It's normal behavior and it makes it impossible to determine a CPU bottleneck by just looking at the CPU usage.

if looking at cpu usage does not determine then how to determine?

GPU usage below 100% while fps target isn't reached.

my fps target in reached at 120fps .This almost look like the game will not render more then 120fps
