[SOLVED] Cpu running at 100% - Gpu between 0 and 50%

[melon_limited]

Good afternoon all,

I have had an issue with some games using 100% of the cpu instead of anything from the GPU, somtimes even sitting on 0%

It has not been an issue up til now as the cpu seemed to be handling it, but i am trying to play cyberpunk 2077 now and the GPU just sits at 0-50% whilst the cpu is at 100%

My rig is

CPU - i5 9600kf - overclocked but i have tried it at stock and OC with no change. overclocked at 4.6ghz
CPU - water cooled
GPU - 2070 super
GPU - stock fan cooled
MOBO - h370 auros
RAM - Corsair vengeance pro 16GB X 4

I have gone through nvidia control panel to make sure my open GL is set to my 2070.
My monitors are plugged into my GPU, as the 9600KF does not support ntegrated graphics.

I am struggling to believe that a 9600kf is bottle necking my GPU that much?

Any help or thoughts would be appreciated.

I have attached pictures to show the task manager and msi open. let me know if i can send anything else to help problem solve🙁

was this an upgrade build? what the cpu temp?

was this an upgrade build? what the cpu temp?

The only upgrade i have made is going from a 2060 to a 2070 super. I built the rest from scratch almost exactly 1 year ago

The cpu temp i am watching atm, doesnt get over 50 degrees c. mostly hovers around 40

Might be relevant, but i updated the cpu details (overclocked at 4.6ghz)

make and model of the psu?
ssd or hdd?

PSU is EVGA 650 GD

It's actually entirely possible that you are being CPU limited, check it out - https://ark.intel.com/content/www/u...-9600k-processor-9m-cache-up-to-4-60-ghz.html

Notice something interesting? The i5-9600k(f) shipped with 6 cores and 6 threads, no hyperthreading (a stupid product segmentation choice by Intel). Now look at this: https://ark.intel.com/content/www/u...-4790k-processor-8m-cache-up-to-4-40-ghz.html

This is the CPU officially recommended for 1080p high settings. It's a 4 core / 8 thread CPU.

This tells me that Cyberpunk 2077 is expecting a minimum of 8 threads available to work with, and your CPU (because it has no hyper-threading) only has 6. This squares entirely with your CPU being maxed out and your GPU being underutilized.

Allow me to quickly quote myself from and old thread where I explain the rendering pipeline and CPU bottlenecks:

"When you play a game, your CPU requests data from your hard drive/RAM and renders certain parts of a frame. It then sends the pre-rendered frame to the GPU so that the GPU can do the portion of the frame rendering that it is responsible for which is then displayed on your screen. Thus, if your CPU isn't fast enough, certain types of games will overwhelm your CPU, causing your GPU to be underutilized because it can't begin rendering a frame until it receives it from the CPU. "

Thanks for the time you spent on that message,

That was really informative, just didnt want to hear it haha

Thanks for your time. I may have to look into picking up a new cpu!

Thanks

Sure thing.

By the way, you gave yourself best answer.

A thread is not a universal unit of measurement, neither is it an absolute value.
8 threads on a 4/8 CPU will, or at least could, run the threads at half the efficiency a lot of the times so they will only run half as fast, which would give a clean 6 core CPU a big lead in performance.
IT DOESN'T WORK LIKE THAT THOUGH.
You can not make blanket statements concerning threads you have to run performance tests to come up with real numbers.

As you said, just because the 9600k has 6 'clean' cores doesn't mean that it'll necessarily be faster (as we might be seeing here). I don't have a 9600k to test, I don't even have a copy of Cyberpunk, so I can only extrapolate my best guess based on reviews I've read and any other available data.
