What Type of Bug are you experiencing?

Steps to Reproduce

Create a verse device and a material with 200+ instructions with a few parameters
In the verse code, add
Sleep(10.0)
Material := MaterialName_material{}

Expected Result

Normal gameplay without fps hitches

Observed Result

FPS hitch 10 seconds from game start, right when the material is instantiated

Tested again and it seems that the fps hitch happens even when creating a material with just one texture, however other material creations made shortly after the first one do not cause a fps hitch.

Hey folks, this issue should be resolved come the 40.00 release. If it still occurs after the release, please thread additional info here or start a new forum post

Thank you very much, would this also resolve our verse vfx issue causing a hitch on initial spawn

I believe this change was catered towards materials so it may not resolve that issue with vfx

Interesting, we’ll report back. Let us know if any updates on the VFX as well.

I’m wondering if we are having the same issue as this. When this happens for you does it happen to every player at the same time? When the players respawn does it fix it? Ours is more of a movement stutter. If the player just looks around the fps seems normal.
