UE 4 vs UE 5 - Instanced Static Mesh performance comparison

Описание: Unreal Engine 4.27 and 5.5 - comparison of Instanced Static Mesh Add and Remove operations.

Lumen, VSM, Nanite, TSR are disabled. Recorded in Editor, but performance is roughly the same in packaged builds in this case.
Win 10, DX12, RTX4070ti

Note: While static performance is worse in UE5 because this is recorded in Editor, the Add / Remove operation cost is almost the same in the Packaged builds, as it appears on this video.
So, UE5 is much slower when adding an instance.
