EndFlushResourcesRHI? What is it and why is it spiking some frames?

Hi all,

I have some spike frames while the camera zooms out of moves with high MS being caused by “EndFlushResourcesRHI”.

Unfortunately I’m not able to find what this is for the life of me to fix the issue.

I have reduced the draw calls, triangles and rendering settings with no noticeable effect.

Noting this is on Android, meaning I don’t have visibility on GPU through Unreal Insights.

Full read out for a frame for reference:

Any help would be greatly appreciated!

Hello!

The way culling works on mobile is different. You know this.

It could be because of a lack of (automatic) culling, so as the camera pans out, it must instantaneously render swaths of objects.

Again, not sure how you have your culling methods set up, but if you haven’t already, it may be worth it to look into Culling for Mobile Devices.
