LOW GPU USAGE ?!

[Mihai_89]

OK so i was looking at my GPU usage in the game and it's like only hitting 65%

Normally this should be a 99%

So right now im getting around 60 FPS sometimes going a bit above and sometimes below on an RTX 4060

The thing is though - i looked up multiple YT videos and the RTX 4060 should be getting around 85 FPS.

Has anyone had this happen ?

While i was in the menu i noticed i had Nvidia Reflex Low Latency turned ON

I decided to turn it OFF just for ♥♥♥♥♥ and giggles - my GPU usage skyrocketted from 65% to 99%

Didn't read the newest posts in this thread, just wanted to let you know, that exactly this is a confirmation that it was a cpu bottleneck.
If you turn on Reflex, it tries to keep the pre-rendered frames at a minimum, basically making your gpu wait for your cpu.
Turning off Reflex allows the cpu to send 1 or more frames to the gpu to render ahead of time before the gpu is done rendering the current frame. This gives the cpu enough time to already prepare the next frame or "catch up" to the gpu.
The downside of allowing these additional frames is that these "prepared" frames are actually "old" data, so when they appear on your display, they don't actually represent the current state of the game, introducing latency.
In your case the additional latency is very likely preferred over the lower fps.
Btw. "cpu usage" often just shows a percentage of how much load is on the individual cores of your cpu. so if you have 4 cores, and 2 are under full load, cpu usage shows up as 50%.
Now what about a game that can only utilize 2 cores?
If your individual cores are actually not that fast, they can indeed cause a bottleneck.
So compare that to a more recent cpu which has again 4 cores, but faster individual cores. CPU usage might again show 50%, because 2 cores are under full load, but this time the cpu can actually keep up with the gpu, because the cores are simply faster.

Always the same story "I have no 100% CPU Usage. so it can't be a cpu bottleneck" - And its so simple to check it, check the Frametime and you will see, if you don't have a straight line with less than 10 ms, your CPU is too weak. Just to compare, my 7950X3D has with my RTX 4090 between 3 and 5 ms in games, the jumps are less than 1 ms, thats a perfect match up between CPU and GPU. If you have more than 10 ms or many jumps then you have a bad match up.

Found on YT, Try to disable rebar in bios, it helped me to boost to 99% on 5090.

It's not CPU bottleneck - RYZEN 5 3600 and i also measured the CPU usage.

What GPU driver are you using ?

I'm on nvidia 572.42 and most videos i've seen are on 572.83 but i heard that one gives black screens and even OS slow-downs.

Vezi ca e de la procesor. Normal, procesorul asta nu e prea slab pentru a mentine peste 60 de frameuri pe secunda, dar TLOU part 2 compileaza shadere in timp ce te joci. Eu am un RX 7600, echivalentul AMD al placii tale, si un 13400f ca procesor, care este mai bun ca al tau. Am 76% CPU all core usage averages, ceea ce e insane pentru un procesor cu 10 nuclee. Si pe langa asta, 13400f - ul meu tot imi da bottleneck la RX 7600 in unele zone, cu 3-5%. Eu sugerez sa iti dai lock la fps la 60 fps cu Riva Tuner de preferat, sau cu in game fps locker-ul pentru a reduce micro stutterurile. (daca nu iti maximizezi folosirea placii video, clock speed ul o sa varieze enorm la placa video, si o sa cauzeze probleme. De asta iti recomand sa faci asta.

You're a dummy. Sorry for stating this. The reaosn you're maxing out your 5090 now, is because you're losing fps. With REBAR disabled, the game can only access your GPU's memory in windows of 256MB of memory each, which significantly drops fps. Turn it back on.

Replying to this just to mention that the frame time graph will also be affected negatively by high VRAM usage.

Yep, it’s low. 50-55% on 4k native, max. settings (4090). But my FPS is capped to 120, that’s why. The reason for low GPU usage is the lack of significant graphics improvements over the PS5 version, they look almost identical.

At the end of the day I don’t care, the game runs flawlessly on my 4090. I was expecting a little bit more graphics improvements over the PS5 version but I can live with it, it still looks OK.

[WhiteSnake76]

On both my AMD Rigs i get high 97~100% CPU usage, with ReBAR enabled, so must be Nvidia driver problem.

[Mihai_89]

So i beat the game earlier, not sure if anyone had this issue until now.

At the resort level in Santa Barbara the game always crashes if the player dies - so far the only fix i found for this is to put everything on LOW and then crank them up again once you get to the beach level.

I tried every preset - very high, high, medium they all crashed, the only one that didn't was LOW but after you get past that area and get to the beach you can crank everything back up again.

I got around 100 fps with 4060ti 8gb. High preset, 2k dldsr. Dlss quality.

I pushed the Graphics with ReShade way and beyond. Looks 10 times better than max settings only.

What GPU drivers/ dlss 4 through the app and CPU you using mate. That's quite good performance considering.

His info ins accurate - i myself literally on my regular 4060 got 80 FPS on very high settings preset and around 100 FPS on high preset after i turned off nvidia reflex.

I am using driver 572.42 not sure if it helps or not.

What i found if very weird is that when i got to THE RESORT level if you die there, when the game loads back up, it will automatically crash no matter what - up until that point i had no crashes whatsoever.

The only solution i found to that was setting everything to LOW until THE RESORT level finishes.

[PLAYUH]

I had the same issue - the game started using only 80% of gpu out of nowhere after a few hours - no matter what settings I tried.
What worked was unchecking "read only" box on the game directory, turning off the FG in the launcher and turning it on in game.

Hey you’re an idiot. It helps use the full GPU and boost FPS, so what’s the problem? Until they fix the game that’s a fix.
