UI has High GPU usage

Development Programming & Scripting
1

Hi I have a scene with a character and an inventory widget along with a seperate crafting table widget

When the widget is up my GPU usage is high, although I see that on Asus GPU tweak 3

The widgets size are 1200x800 with an image as the background that I made from a screenshot of the 3D mesh (2k graphics)

Now I am pretty new, I’ve been using unreal engine for the better part of a year, so please be gentle :pray:

My PC specs are
Asus 4060ti
Intel i7 13700k
32gb Teamforce ram @6000mhz
Asus rog strix z790e DDR 5

Is there any way I can lower the GPU usage not only for me but the players when they have a widget up?

Any more information needed I can provide

What does “GPU usage high” mean.
Are you actually GPU limited, such that the frame rate is limited?
If so, are you pixel shader or vertex shader or texture read bound?
You might start looking into this using the built-in diagnostics tools:

If the “high GPU usage” is just some percentage value that goes from A to B in some control panel, and nothing really changes in your game, then it’s unlikely to

  1. matter
  2. be easy to debug

Also, is this when “play in editor” or when running the packaged game?

This is when I play in editor, my GPU reads 50% usage which is weird for widgets. But when I check the GPU on the editor side it, it doesn’t seem to make much of an impact at all.

No frame drops, no serious repercussions. Trying to make my game mid-grade PC friendly

Thank you for the link, I will read this right now.

Does the image you place as a background have any impact on the GPU?

My two cents:

profile gpu
r.vsync 1
t.maxfps 60

Anything can have an impact on a GPU. For example, a very high resolution image without MIP maps, will cost a lot more to render even when it is small, than an image that has proper MIP maps.

That being said – I would be very suspicious of any “tuner tool” measurement of “GPU Load.”
What matters is frame time within Unreal Engine for the packaged game, mostly, and a little bit what frame time you get in the editor (because you need to keep working with the editor, and low frame rate isn’t all that helpful for editing …)

Wow this is very helpful, I will redesign my widget textures and do my homework on those maps.

Also it turns out a couple assets I got from the market place (one I got for free so whatever) but the OTHER one was sold to be 2k textures but had the base of the mesh as a 4k texture.

So I had a few things in my scene that were actually 4k textures, significant improvement after replacing those meshes.
