In rendering , my ue5 doesn't use GPU or CPU!!!!


This is my laptop’s Control panel while UE5 is capturing a 4k animation.

as you see It doesn’t use CPU or GPU . It uses RAM(memory)

My GPU is GTX 1650. also UE5 almost never uses GTX1650!
How can I solve this??

Hey @Araz_rajabi!

Unreal does use a decent amount of Ram, even with a decent graphics card. However, when using task manager and having it selected, that may not be an accurate representation of what resources unreal is taking.

Unreal by default has a feature that reduces the performance and resources taken when in the background (not the main window). You can either make sure that your task manager is completely visible while you have unreal selected as the main window, or go to Edit → Editor Preferences → Performance → Use Less CPU when in Background and untick that box.

Unreal not main window in use:

Taskmgr_MoQvdyWs0Q

Unreal main window in use:

Taskmgr_a5uceP9CzI

I hope the above clears any confusion!
