CPU not going over 50% load

[pseudo zealot]

Specs:
OS: Win10 x64
CPU: AMD Ryzen 5 3550H with Radeon Vega 8
GPU: Nvidia Geforce GTX 1650 Mobile
RAM: 2x8GB DDR4 2400 MHz
DIsk: SSD
Other: AMD FreeSync-compatible display, 120 Hz

issue: Last time I played (ALT R3), the game would utilise all resources available, with stable 119 FPS on low-mid settings, and the advanced graphics settings actually worked. Now I have to set the resolution to 1600x900 for the game to run at 90 FPS with the same settings. Other games run fine, no hardware issues, and the stupid mistakes (like selecting the iGPU to run the game or not enabling hardware-accelerated GPU scheduling) have been checked off the list.

What's funnier is that when I disable Threaded Optimisation in Nvidia Control Panel, the CPU loads to 100% just fine, but the performance does not improve.

Attached are the Task Manager readings and the Display settings. Low settings, Half texture size, 2 frames in render queue.

Use the recommended settings in this guide and see how it runs

on 1080p

you dont actually want the cpu to be at 100%

you want the gpu to be

[cerulean quest]

yeah

you want your cpu culling workload to be set to low

[pseudo zealot]

Already done, nothing changes. The CPU culling option stopped working.

[pseudo zealot]

I know that, but I want BOTH the CPU and the GPU to perform, and no matter what I do, the CPU never goes above 50%. Almost like something's wrong.

[cedar copper]

if the cpu usage is low, then that means that the gpu is the bottleneck, and is holding the cpu back

there will ALWAYS be a bottleneck

you pretty much always want low cpu usaage, but max gpu usage

gpu only does the game

cpu has to do everything else as well

as long as the cpu can max out the gpu, nothing is wrong

also, this game is very single threaded since it is built on unity

the highest i see overall on my pc is about 30% usage

but sometimes around 80% on a single core

[pseudo zealot]

That's all I needed to hear. Explains the time I turned SMT off in BIOS and CPU started performing again.

[cedar copper]

turning off SMT can help with games sometimes

sure having it on does give you more multithreaded performance, but i can hurt single threaded performance

CPU is bottleneck for another reason tho sometimes. It's the problem of game just not utilizing all the cores and mostly being active at 1 or 2 cores most of time
