GPU not being used

[Ol' Pappy]

The game runs fine but the GPU usage is about 1% while the CPU does all the work and at times generating lots of heat. Yes, all the drivers are updated, all the patches patched, yadda yadda. AMD Rysen 7 5800X3D, NVIDIA GeForce RTX 3080Ti, tons of memory, SSDs, etc.

Weird. AMD here and I find the opposite.

Suspect you're trying to measure GPU usage via task manager? It's horribly inaccurate.

You'll need something like afterburner, or even geforce experience to measure your actual usage.

But you'll put out some heat, sure.

game isn't optimized and made to run on a xbox 360 why you think it looks so dated compared to cp2077.

The CPU cannot "do all the work". Mant0r is right. Don't use Task Manager expecting to see actual GPU usage. It's been broken for GPU usage for years now. Use Afterburner/RTSS, HWInfo, any other dedicated app for seeing what the actual usage is.

1% GPU usage would mean less than 1 FPS for most people.

Like mentioned, task manager gpu usage is bugged. If the game wasn't using your gpu, then you would be lucky to get 5 fps.

Have you used the Nvidia Control Panel and forced it use the GPU instead of Auto Select?

1% are you sure? I know this might sound daft, but it does happen... Have you made sure your monitor is plugged into the correct port? As it sounds like it is connected to your motherboards integrated monitor port, rather than through the GPU ports.

My 3080Ti runs at an average of about 80% usage on all ultra settings.

Task Manager lies.

[Weird Potato]

No way it's using 1% of your gpu. Your frame rate would be single digits if it even ran. Maybe stop staring at performance metric, especially ones notorious for being inaccurate with gpu usage like task manager.

I am using NZXT to measure usage, not the task manager. A good indicator to confirm usage is the amount of heat generated. The CPU is cooking pretty good, but the GPU is nice and cool

Yes. Nothing changed..

This is not what that number means. The numbers do not mean the game is using some % of your GPU or CPU. That isn't even measureable. There is no code that will use 100% OF a CPU b/c by your definition that would mean all circuits are being used. The percentages are all about how much of the OS allotted time slice each device is using. It has nothing to do with 'how much' of the GPU or CPU is being used.

I can easily write code to force all cores to any percentage I want. That doesn't mean the code is doing much of anything, however.

OK some guy made a false assumption that I was using task manager and you all went with that. I am not using task manager. My graphic card is as cool as a cucumber while the CPU is nice and hot, a crude but reliable way to confirm.

I run 3 monitors. I play DCS in VR, or sometimes on my monitors with a head tracker. I know what I'm doing. But I am curious about your setup; you have the same GPU as I do, and you are able to measure GPU usage? What program are you using to measure it ? How is your CPU usage? I'm a bit baffled here because I run many demanding games and the tools I use for measuring performance are usually reliable... Hence this thread.

[Ol' Pappy]

Just to illustrate the situation: I just ran DCS, a simple P-47 sitting on the ground: CPU usage 24%,GPU at 70%. Then I run Starfield and I get 35% CPU usage, 2% GPU (this is standing around inside the ship). CPU usage goes much higher in a city, of course but GPU stays the same. I have Ge Force Experience opened, it sees the game and I had it optimize the settings. The NVIDIA control panel, in manage 3 d setting, has Starfield customized, and I will try to play with the setting again to see if it changes anything. I will get rid of most of the "application controlled" to see if it does anything.
