This is known, but I want to raise this as an official issue.
Sleep(0.0)
has a cap of 30 ticks per second.
The biggest issue about this is updating object’s transforms for smooth movements, specifically Blueprint Props and Skeletal Meshes.
We all currently use TeleportTo, which perhaps, might not be optimized. But raising the max ticks to even 40 per second would fix this and open a lot of features for developers.
Of course, unlimited ticks per second based on hardware combined with delta time would be ideal. I have at least 10 shelved projects that would come to live by increase the tick cap.
You can see some of the issues we are dealing with in this video here:
