CPU Usage

[KahnedAR]

Hey, so I just did a benchmark and it looks kinda weird to me, GPU usage is almost at 100% when CPU is on 3%, is there something wrong with this or I'm missing information of how should this work?
Any way to lower GPU usage for a cost of CPU?
Thanks for any replies!

You always want gpu usage at 90-100%. thats how it suppose to work. CPU usage is weird but it might be just showing a single core. Whats your specs

its better that the gpu is working than the cpu i guess always 100 gpu and less for the cpu to handle other processes

This isn't terribly uncommon. I wouldn't worry.

You always want your games to be GPU bound. This means your GPU is the bottleneck for how many frames can be put out and it isn't waiting on the CPU. Exactly as it should be.

Well and this is why I asked this question, I wasn't sure about that, thank you guys.

Microsoft broke CPU utilization monitoring in a recent Windows update. That's probably the reason it's reading so low. If you check the Task Manager it should give you the correct number. But like others said if your GPU is at 100% then you're fine.

Can you explain why?

Wouldn't almost 100% GPU utilization just mean that there's no reserve left when a more demanding scene needs to be rendered? If you walk around with 95% and then a battle starts with more characters and effects, you're gonna get frame drops. If the GPU chills at 70%, there's still enough capacity?

Of course, you wouldn't want a CPU bottleneck where the GPU is at 70% but you can't get 60fps because the CPU is at its limit. But how would >90% GPU utilization most of the time be a desirable metric? Just means that for the next releases, you're soon gonna have to dial down the settings to prevent your GPU from capping out?

I think you're misunderstanding what these numbers represent. GPUs can't keep a "reserve," they always process instructions as quickly as possible. If the GPU utilization is reading below the high 90's, that means there's a bottleneck elsewhere in the system which is generally a bad thing unless it's due to a framerate limit. When the framerate drops during heavier scenes that's because that's as fast as your system can render that scene, you can't just save up GPU power to use later. If you don't want the framerate to fluctuate as much, you'll need to set a framerate limit to prevent the framerate from going too high in lighter scenes.

Aight, I was assuming that an fps cap depending on the monitor's refresh rate was used.
I didn't mean that a GPU uses free resources to render things you might need later, now.
