GPU usage decreasing over time in game

[jaexy]

Hi!

 

Specs:

12th Gen Intel Core i7-12700K (AIO cooling Waterforce 240)

NVIDIA GeForce RTX 3070 Ti (KFA2)

16GB (2x8GB) 4600MT/s (F4-4600C19D-16GVKE)

 

Gigabyte Z690 AORUS ELITE DDR4 (with latest BIOS update F29)

Samsung SSD 860 EVO M.2 1TB

 

So I have a specific problem with one specific game: PUBG

 

Problem is that I know that on these specs the game should run easily 300+ fps on low settings. I can see from CapFrame that my GPU is kind of "lazy" - that when playing on low settings, it wont use all the load and the load is decreasing over time.

 

So pull on low settings reveals exactly on what I just wrote:

 

And pull on ULTRA settings shows that I am having basically the same FPS, but now the GPU is doing its work.

 

I have also asked one friend of mine to have a pull on Z790 mobo, and he is facing the exact issue. Meanwhile I have another friend who did also a pull for me to compare and it looked like that:

 

I have a suspicion that it might be MOBO based problem, but after going through hours of tweaking BIOS and so on - I have yet to find the solution. Does anyone have any good ideas or knowledge that why is GPU acting this way? Or could there be anything else behind it? 

 

Any thoughts/recommendations or anything is highly appreciated!

 

All the best from snowy Estonia,

PUBG is a CPU and memory heavy game so CPUs like Ryzen 7 5800X3D or 7800X3D will work best due to the large cache pool... almost all battleroyale games behave the same way and performance will always vary wildly depending on which stage of the match you're in and how many players are nearby.

 

There is not much you can do besides overclocking your CPU and memory to get some more performance.

I agree, that it is CPU heavy, but I mean if You look at the pull of my friend. Which is even slightly weaker CPU than mine, he is running stable 280 avg fps and the GPU load seems also much nicer and more consistent...

Can't really compare that as both systems are wildly different. I get what you're saying with the avg FPS being higher on your friends PC but that can be a run to run variance as I mentioned the game performance varies wildly depending at which stage of match youre in, where on map you're located and how many people are nearby.

 

You would have to test the identical scenario every single time to make a more fair comparison as you can have like 50FPS+ run to run variance in PUBG depending on how you test it.

 

His GPU is slower so he will be pushing it harder and thus will have higher GPU usage most of the time than you.

His CPU is basically the same as yours. The extra cores you have are not really relevant for PUBG and you will hardly notice a 100MHz difference in boost performance.

Use DX11E, try DX12, avoid DX11 cause it can't use more than 4 cores.

Update your drivers, firmware, bioses/vBioses, ...

Disable MPO.

Dunno sh#t about PUBG, I'm a boomer lol, but I see 4600MT RAM, it's super slow for DDR5...

Oh sorry, if I was unclear - it is DDR4. I previously had TridentZ DDR4-3600 CL16 - but this was too slow. So I loaned a kit of Ripjaws DDR4-4600 with CL19 and gained like 40-50 avg fps... PUBG is crazy about RAM as it is so poorly optimized game... And getting low latency/high speed RAM in Europe is a headache. I wont even start talking about getting a RAM with Samsung B-die stone inside of it...

Thank You for thinking along! Both I and my friend have done about 20 pulls, and similar patterns are drawn over and over again. All the pulls are also done in Team Deathmatch, which is like 5 minutes of 20 players on a small area. I mean it is just odd that the GPU thinks that okay, my holy father is playing on low settings, so I don't have to do anything also. But still I am not even 100% sure, that the missing FPS is the fault of GPU load decreasing...

 

I have also tried clocking to 5Mhz, but the result is pretty much the same...

Pubg is a poorly optimized game. Sorry for what you are experiencing.

I agree, but having been a long time player and buried many hours into it, I am desperate to gain some valuable frames stability... Even more when I see similar or even worse setups than mine running the game stable 300+ fps in any maps or scenarios...

Your best bet is to do what 191x7 suggested.  I do not know what OS you are using. If it is Win-11, that has some fps drops due to bad windows update patches.
