Hello,
I’m new to unreal and opened the city sample project. It gets around 40 fps but gpu usage shows 1-3% and cpu usage is around 30%. How do I make unreal take full advantage of the GPU
Just checking. You know when you open the task manager in windows and look at the GPU, you need to click on Unreal in the background again to measure it?
yes the active windows is unreal and not the task manager
Do you have more than 1 GPU? ( Integrated one on the motherboard? )
I have integrated gpu but it is also %0 all the time
Ok, what is your GPU? ( and CPU actually. TBH I’m not sure what the problem is at the moment ).
They are Rtx 4090 and Ryzen 7900x. I am also confused because all the project settings are at max.
But does it perform ok? What’s your frame rate. Sorry for all the questions, quite difficult to diagnose at a distance… 
When not moving around 40 but when moving around 20.
The only thing I could find was this
It says the city sample got bad fps even on top end GPUs, even though it was not using the GPU capacity.
I think maybe, try more projects / demos, to get a better idea if it’s just the project, or something to do with your config.
I have seen many videos with above 100 fps with identical systems. But the Lyra project has around %13 GPU usage. Which options effect GPU usage in UE5
There is no ‘use the GPU more’ setting, it just happens when you crank up the quality.
There are all at cinematic but I think there might be something wrong with the software. Thanks for helping.

Hey there @Kl0120071! Welcome to the community! Clockwork went over my original thought for this, which was that it could be utilizing your internal GPU more than your external, but if neither is showing much usage and the frame are dropping exponentially there is a bottleneck somewhere. Say if the shader’s are still compiling while you’re working, can cause quite a resource bottleneck, and many laptops (even more powerful ones) will take quite some time to work them out.
Worst case scenario you can start profiling your scene to see where the holdup is, GPU or CPU.
