Why game uses so much GPU?

Hi guys! I’m wondering why UE4 uses so much GPU, for example, here is GPU usage of default 3rd person example in 120 FPS( if I package the project it will be like 10-12%):

And here is GPU usage in Doom Eternal game in 180-200 FPS:

As you can see Doom(which is on my opinion is much more complicated) uses like 7 times less GPU than default example of UE4 and even with more FPS.

So what’s the problem with UE4? I’ve tried to change some settings, turning off post process and so on, but nothing give me a significant result.

Thank you!

I think you got it in a nutshell there. DOOM is packaged, obviously. When you’re running in the editor there’s a lot of extra overhead.

Hi, I’ve mentioned in my post that packaged UE4 example uses like 10-12% GPU, which is a lot for this kind of project
