High Res, all ultra and it's 40-60% useage with CPU (11900k) at 30-50% useage?? Historically all my GPUs have sat at 99% useage. It's the same with Vsync on in NCP (100fps) on chance off (160fps). Could be a PSU issue? (850w)

Must be game related as it's 99% usage in Unigine Heaven with a benchmark score of 6313 (250fps) (High Preset at 3440x1440)

That particular game (BFV) must not be loading CPU/GPU up enough then?

I always thought GPU would run at 99% usage all the time no matter what?

Some games are FPS or CPU thread limited. So if the game has some code that is slow/clock locked to the compute/ai/etc, then the FPS can hit a hard limit.
Especially true in some driving games where framerate was locked as it's physics calculations are locked to framerate. Also true for some other games (IIRC Fallout 3 had this).

Without knowing the games code though, hard to accurately speculate.

Interesting, my old 1080ti and 7700k would have the GPU pinned at 99% in BFV so I just assumed the new hardware would be the same.

99% of what?
Percentage is a measure of use, not unit. 99% at what fps, and what resolution? 99% of what compute ability vs the 3090? It could be the game engine not understanding how to use a 3090 (mistaking 24gb vram for 2gb vram due to poor coding not allowing 2 digits of ram utilisation and just reading "2.4" in error, but rarely does that happen nowadays, more a 1990s/2000s game engine problem).

A Nissan Micra doing 99% performance might be it going 80mph, a Porsche doing 80mph is only like 49% performance. So if the road is limited to 80mph, you'd get the same result as a 3090 and the game being limited to 160fps.

"Fair enough, I just seem to remember all my GPUs always sitting at 99%, maybe I've just been hammering them all along lol."
Then you were not CPU limited, but GPU limited. Now you are CPU (or game engine) limited. You mistook 99% to *be* the unit measurement. It's not. It's telling you the GPU is working full speed, but not what that speed is. :p

PS, providing you are getting the FPS results though. If your getting 50% gpu use and only 30fps, then something is wrong. That's when you look for power failures, bottlenecks or driver/game bugs. :)

99% useage, as in GPU useage.

If using vsync or a hard fps cap then yes then pretty much normal, if not and it’s off then it should be at 99% or there abouts even with an RTX 3090.

Id find it hard to believe that the 11900k couldn’t keep up with it especially at 3440x1440. Especially to the point of only using 40-60%.

Make sure you’re using normal DX11, DX12
On BFV is usually just trouble and never has ran right.

This is what I thought, I've played some Cyberpunk and the GPU usage is pinned at 99% as expected, with CPU at 30-40%.

So my initial problem is probably related to BFV then, maybe some weird combination of settings including DX11/12. I'll see if I can dig out the settings I used with my old CPU/GPU and apply those to see what happens.
 
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?

You think I'm not taxing the new hardware enough? That did also cross my mind. I did try ray tracing but it just made the game jerky and the FPS went to 80. Can't use DLSS on BFV because it's DLSS v1 which does not support Ultrawide resolutions. I could try upping the Res scaling in game to see what that does.

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
Click to expand...
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.

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.

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.

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?

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