pubg low gpu usage

[ahmadsamir]

my specs :

r5 2600 (non oc)
rx vega56 8gb (oc + uv)
2x8 3200MHz ram

i don't know what is the problem since i play any game without issues
but when i play pubg, i have a strange gpu utilization issue
ultra settings = 95% or above gpu usage = 80 - 100 fps
competitive settings = 70% or below = 60 -90 fps

every thing is perfect ( bios up to date - set xmp to the max - win 10 up to date - all drivers up to date )

I have no idea , very odd. And this is the only game thats causing this issue for you?

 

[Hyderz]

what power supply do you have?

yes, thats the only game cause this issue

what power supply do you have?

700 watt 80 plus (cooler master masterwatt lite)
i think there is no problem with it , i test it with many different benchmark programs like heaven for about an hour and the watt consumption is stable .

It isn't the power supply. You dont get less fps if it is failing.

When you say competitive settings, what exactly does that mean compared to ultra? No resolution change right? Just turning a bunch of settings down? 1080p, yes?

If you overclock the cpu, do you get more fps and GPU use?

 

[ahmadsamir]

yes the same resolution 1080p, all settings on very low except AA and Texture on ultra , oc the cpu to 3.9 make no difference to gpu usage and fps .

 

[EarthDog]

CPU's default speed is 3.9...

PubG is unbalanced and doesnt typically run all that well on AMD hardware, your also using an Older AMD GPU. Back when the game came out aa Vega 56 was lucky to get 60 FPS when a 1080 Ti was getting a 120+

Even as they have improved the game performance on AMD GPUs has never really been stellar. So while performance has improved at the end of the day PubG remains fairly unoptimized and at 1080p Ultra settings performance is all over the board and dropping settings doesn't typically improve performance all that much. The game is just a hodge podge of issues sometimes its great other days forget it.

In today's version of the game going from say 1080p ultra to 1080p medium on a Vega 56 your likely only to go from around 90 fps or so to 110 fps or so.

Its the game not your hardware and a google search and reviews of the games performance will tell you this.

Back in the day PubG tried suing Epic over support of Unreal Engine 4, at this point Epic has fixed all the major issues they were having but PubG made a bunch of changes and custom code, so older engine, with issues numerous patches and fixes to gloss over issues results in a game that honestly doesn't run that well considering the level of hardware you can throw at it.

Last i knew the game was using unreal engine 4.14 or 4.16. Considering that was 2019, and the Unreal Engine is on 4.25 with Vulkan support. With the launch of version 4.2 of UE they typically saw a 30% performance bump on AMD hardware. Obviously PubG hasn't gotten there yet and likely never will. Games fairly old now and their mismanagement and lack of improvements and drawn out issues means Fortnite eclipsed it long ago. Even if I still prefer PubG myself its no longer the shiny battle royale game.

yeah its not failing , but could possibly be not supplying enough juice..

Again, power supplies do not 'brown out' and cause lower fps.

I usually recommend downloading GPU-Z and checking the PERFCAP reason.

my cpu can not reach 3.7 don't no why ( update bios to latest and enable D.O.C.P )

i think PERFCAP is for nvidia only ?

Woops! You are correct.

That would be your problem. As you start scaling down graphics, the CPU becomes more of a restriction (doesn't mean it is, just more prominent).

If your CPU can't get past 3.7 you either have miserable cooling or you need to check some UEFI settings.

Off topic but I love how competitive settings mean making the game look like shit.

Edit: Also, if you don't have a monitor with at least 100fps, then you are chasing stuff that will do you no good other than fixing this a clock problem.

Time to time the same happens to me, 1080p.

Classic old game CPU bottleneck problem, Ryzen 2nd gen has not enough clock to satisfy this game which underutilizes modern CPU's (doesn't use all cores the CPU has). But you can be happy it is only 5% GPU util that you're losing out on. I had much worse problems with GTA 5 and 1080 TI before I switched to the new system.

PS. I'm not sure the "overclock" you did for just 200 MHz over baseclock is worth it. I'm pretty sure it is not. AMD Ryzen is best left alone, the max single core boost is 3.9 GHz, a lot better than the manual clock you chose. I would try, reverting back to that and using PBO / XFR2 instead.

I just find the answer! Your AMD gpu are limited by your limiter power in your panel settings by default 0, just slide to 10 to give all the power that your gpu needs and you will get the 100 usage
