[SOLVED] i5 8600k 100% Usage

[FunctionalGaming]

I was just testing Shadow of the Tom Raider on Highest preset settings on my 1080p monitor, after looking at CPU performance it is at 100% a lot of the time and my GPU is very low. I have an i5 8600k overclocked at 4.7GHz and a GTX 1070. I am looking to upgrade to a 2080 super soon, is the CPU cable for a 2080 super?
Thanks

What resolution are you running? What FPS are you achieving? Does your overclock of 4.7GHz hold while in games or is there any throttling happening? What is your average gpu usage?

You might be cpu limited. There are games that can saturate the hex thread i5’s.

So for Shadow of The Tomb Raider I did:

• Full screen 1920x1080p
• Vsync off
• And the highest preset

FPS	CPU Game	CPU Render	GPU
Min	85	79	63
Max	164	277	140
Average	121	124	85
95%	90	81	71

Also says 96% GPU bound.


Far Cry 5 max preset at 1920x1080
Minimum FPS: 84
Average FPS: 93
Maximum FPS: 105

The 4.7Ghz holds and the CPU usage flickers from around 70 to 100, mostly towards 100.

I would read that as the cpu and gpu are currently well balanced and although the gpu is largely the limiting factor the cpu is also being heavily utilised. Therefore a gpu upgrade will extract more fps but I would not be surprised if a 2080 Super is held back from its full potential by the cpu if you stay at 1080p.

Wrong question. That cpu can handle even a 2080ti without issue. In certain games at any resolution. It's not going to do great in others simply because it'll be restricted to 6c/6t operation.

When you play games optimized and wanting to use 8+ threads, something has to give, and thats a loss of fps as the cpu cannot process as many pre-rendered frames as an 8thread cpu can at the same clocks. And missing those last 2 threads can dump a ton of work back on the 6 available, and usage skyrockets.

But you'll only see that in comparison to the 8/9 gen i7/i9 K's.

There's only 2 ways that cpu is not going to be underutilized. High resolutions or ray tracing enabled. But going with either is going to change the 'balance of power' and even that i5 isn't going to have any problems getting really decent fps.
