3090FE low GPU usage?

use higher resolution scaling options

or use DSR

you're cpu bottlenecked near 120-160 fps. this is pretty normal and common with nvidia gpus. they eat %20-30 more cpu so your cpu bound max ceiling fps will always be lower than AMD gpus due to nvidia's hack

conisider urself lucky if that cpu can hit 100-110 fps in bf 2042 lmao. that game will be designed to push 120 fps with zen 4+ddr5 in mind

oh disable dx12

I think you are on to something there, I put the Res scale up to 130% in game and GPU usage stays at 98% at around 120fps untill the FPS gets near 200 (which is the max FPS BFV can do), at this point the GPU useage backs off to 70-80% because it's hitting BFVs hard cap of 200fps. I think it's just boils down to BFV not being taxing enough for this GPU at 100% res scale.

That was with DX12 on but yeah I'll go back to DX11 because it's definitely smoother.

Although this doesn't explain the initial CPU bottleneck it does somewhat put a bandaid on it for now.

Point: Whoosh.

If I measure 99% on my ruler, 99% of what? The ruler yes. But what distance is the ruler. What processing power is the GPU, and what is it processing? It's a deep and difficult question, but the right one. Until you realise what 99% *is* you'll be stuck wondering why the new 3090 is only at 40%. :p

What we are measuring is completely irrelevant, usually low GPU usage is a sign of a CPU bottleneck. Having just installed a new CPU and seeing low GPU usage made me question if the CPU was setup properly. Either my CPU is just too OP for BFV or CPU utilisation isn't all that good in BFV.

I've played all the BF titles on PC (as well as a lot of other games) and pretty much always the GPU is at 99% usage unless it's an early access game that isn't optimized very well. Before my upgrades even BFV ran at about 60% CPU and 99% GPU which is how it should be, the GPU is almost always the bottleneck in a system so it'll always be running at 99% as it's trying to keep up with the CPU. When GPU usage drops below 99% then the bottleneck has switched to a hard FPS cap somewhere or the CPU which is when you need to find out why.

It really does not matter what the 99% is a percentage of, all you need to know is that the GPU is the bottleneck by seeing it run at 99% usage, that's the sign of a happy gaming system. You always want the GPU to be the bottleneck because a CPU bottleneck makes for a very unstable FPS and is generally not a smooth experience.

I've set everything up exactly as I had it before with my old CPU/GPU as below:

NVCP
G-Sync - Enable for windowed and full screen
Low latency mode - off
Max frame rate - off
Power - Prefer Max
Preferrered refresh rate - Highest available
Threaded optimization - Auto
V-Sync - Off

Battlefield V
Screen mode - Borderless
DX12 - Enabled
DXR - Off
Framerate limiter - 200 (That's the max the game will allow)
Future frame rendering - Off
V-Sync - Off
Graphics - Ultra

RTSS
Framerate limit - Off

So with these exact settings with both my old CPU/GPU and new CPU/GPU the results are below:


BFV (7700k/1080ti)
  • FPS - 90-100 (it would never go over 100 as if there was a hard cap somewhere)
  • CPU Usage - Don't acually recall this
  • GPU Useage - 99% always
  • Smoothness - Always super smooth


BFV (11900k/3090)
  • FPS - 90-160 (seems to fluctuate wildly)
  • CPU Usage - 40-70%
  • GPU Useage - 70% average
  • Smoothness - fairly stuttery at times

Something does not seem right about the performance of the new CPU/GPU, the FPS fluctuates by a large amount, the GPU useage is very low low and fluctuates and the whole experience is nowehere near as smooth as it should be. Could this be symptoms of the PSU not having enough power?

Something doesn't sound right there. I'm on a very similar system and have no such issues. I upgraded from a 6700k (4.7Ghz, almost identical to your 7700k) and BFV is so much smoother on my 11900k/3090. GPU usage is at 100% ,even if I reduce my resolution down from 4k to 1440P.

I'd run Cinebench R20, check CPU scores. What memory speed are you running? What BIOS for motherboard? What speed PCIE?

Exactly, something seems off. I'll get back to you with that info shortly.
 
Could try a clean install of windows and all the latest drivers. Just saying.... could be anything, also unless the system is crashing, blank screens or reboots etc... it won't be the psu, however I would recommend something a bit more but if your worried it's psu related, strip everything out not being used, just a bare system with no OC.

No. It for sure is not your PSU.

People seem to misunderstand how PSUs and power work in general. Power is PULLED, not pushed. There is NO 2-way communication between your PSU and anything else.
Components like your CPU and GPU will pull power from the PSU. Only really 2 things can happen.
1.) The PSU provides the power, and everything works.
2.) The PSU cannot provide the amount of power requested, OCP triggers and your PC either turns off or black-screen reboots.

You cannot get a situation where the PSU 'limits' performance of any component by a little bit. It can either provide the power required, or it cant. No inbetweens.

So, if your not getting restarts or shutdowns, your PSU is not the problem.

On the wider topic, you mention just BFV, how does the GPU run in other games or benchmarks?

Cinebench R20 score = 5808
Motherboard = Asus z-590 Gaming-E
Motherboard Bios version = 0232 x64
RAM speed = 2133MHz
PCIE = 4 (according to CPU-Z)

The RAM is actually 3200MHz but I had a quick look for XMP in the Bios the other day and couldn't see it for some reason, I need to go find that.

Good to know, thanks :D
 
How about some other games? Do you get this issue then too?
What about 3Dmark or Superposition Benchmarks? GPU perform as expected there?

So far the only other game I've played since the upgrades is Cyberpunk and that seems to perform as expected. Time Spy score is 15,300 or something (default at 1440p) and all seems well there.
 
thats normal, 1070ti is low-endish for cyberpunk (won't even be able to push 1080p 60 fps with medium settings). cyberpunk is tough on all gpus so it can easily fill up a 3090 even at 1440p
 
When I ran a 3090 I had the same issue, what I found was that it was hitting a CPU limitation but it's hard to spot. Basically in your monitoring software you need to set the polling interval very low so you can actually see the individual CPU cores creeping up towards 100%. With a standard refresh interval of say 1000ms you find that the CPU appears to be not maxed out because it is constantly sharing the load around, it never runs one core at 100% for a whole second (meaning when it is monitored it might report say 60% utilisation), but it might be up near there for a couple of hundred ms.

That said, a 11900K is better than I have so you shouldn't have as much of a CPU limitation.

Goes without saying but make sure you crank up the settings that are heavy on GPU like maxing out RTX/AA etc.

That's an interesting point actually, well spotted. I'll have a look.
 
Might be nothing, but I noticed you said you have BFV in DX12, which is notoriously buggy, and only really needed if you want RT. Have you tried in DX11 to see if it makes any difference?
