GPU not reaching 100% Utilization despite no CPU bottleneck

[vale crag]

Model:
Lenovo Legion 5 Pro 16ARH7H

Describe the issue:
GPU demanding game like Minecraft + SEUS PTGI maxed at 80% GPU Utilization despite CPU isn't bottlenecking it.
At first i suspected it was due to the TGP limit at 150w, but i tried reducing the game resolution, and the watt usage
also reduced instead of sustaining at around 150w.

What have you tried already?:
Tried switching between power profiles (Balanced, Performance), tried toggling GPU Overclock

When did it start producing the issue:
few weeks ago

Did you install new drivers or software?:
I reinstalled my Windows 10 and used drivers provided by Lenovo website

Can you provide images/videos to show us the issue:

Run a GPU benchmark. If it hits 100% utilization in there, then this is a Minecraft problem. Nothing to troubleshoot.

[vale crag]

Aight, i'll try Time Spy

[sudden smelt]

Sure

i have a sneaking suspicion your CPU is actually what's blocking it

especially given that temperature

it feels to me like there is one core that is absolutely totally maxed out

which is causing cpu bottleneck

[pseudo meadow]

Nah it's just minecraft

Heavily cpu bottleneck'd game single threaded wise unless modded to hell and back with optimization "patchwork"

And even then you might get into engine limitation

Free to use more shaders/gfx effects turned up i can easily hit 100% with lighter shaders than seus ptgi

[gleaming briar]

yes? thats what i said

unless you were referring to OP

[pseudo meadow]

referring to op

[gleaming briar]

oh okay

sorry lol

[pseudo meadow]

np np

[gleaming briar]

yeah when the cpu is hitting 89C with 10% usage

that signals there is one core maxed absolutely the fuck out

[pseudo meadow]

it's fine

it's amd

can go lil further

[gleaming briar]

it's fine, i'm not saying it's not

but i'm saying it means theres a hotspot

i.e. a single core at 100%

[pseudo meadow]

28.6W is low af tho, mhhm true not gonna deny that

[gleaming briar]

so it's definitely cpu bound

KSP gets my cpu to 95C with 60W

while something like fortnite has it chilling at 85C

also at 60W

bc ksp really heavily stresses specific cores

@vale crag if you dont already have them i recommend the fabric optimisation mods

sodium, iris, starlight, lithium

[vale crag]

yeah i might try it later

[vale crag]

but now i'm curious with the possibility of this, i'll try checking the cpu usage per core later

but anyway

[vale crag]

yeah, i've tried Time Spy and Fire Strike benchmarks, all seems normal, gpu hits 100% utilization and the final averaged score from 3 runs is about the same as the numbers shown on various reviews of the same laptop model

[vale crag]

checked the per core usage, seems low mostly. i guess this is just minecraft being minecraft
