stat Game

stat DumpFrame -ms=0.1

Command		Description
stat Anim		Shows how long skinned meshes are taking to compute per tick.
stat D3D11RHI / stat OpenGL		Direct3D 11 or OpenGL RHI.
stat DumpEvents [-ms=0.1] [-all]		Whenever an event is called (say from Blueprints, or for things like PhysX Task functions), they will be written to the log.
stat DumpFrame		This will write to the log information about the frame rendered right after the command is recieved.
stat DumpHitches		Anytime a "hitch" is detected based on *t.HitchThreshold* it will be written to the log.
stat Engine		Shows general rendering stats like frame time as well as counters
