Hello everyone!
I am developing a VR project using UE5.1. My VR device is VIVE Pro 2, and my PC is 13900kf+rtx4080 with 4k resolution screen. I created a default VR project, and at this time, the editor’s frame rate is normal at 120fps, with a GPU 3D occupancy about 60%. When I use VR Preview mode for preview, the frame rate of the preview window is less than 50fps. After closing VR Preview and returning to the editor, the frame rate of the editor was less than 5FPS, and the GPU usage rate was also 95%, making it almost impossible to edit.
What is the reason for this? Is there any good solution?
Thank you everyone
Hello Mio,
In Edit → Editor Preferences there is a setting for ‘Use Less CPU when in Background’ (By default, the editor will use less resources when unfocused/minimized)
It sounds like the editor might be getting stuck in this ‘out of focus’ mode somehow? Try disabling that setting and see what happens.
