Realtime settings not preserved during simulate/play

I noticed that my “real time” viewport settings are being set to true when simulated, but not being reset back to false when simulation stops. I can understand that when you simulate you are running PIE and want to see it update, but I set the realtime off to save performance when editing. As it is now, every time I simulate I have to manually turn off the realtime (which I notice as my gfx card fan spins up).

Can it not preserve the setting when simulation starts and restore it on simulation end?

This is fixed in 4.2, which will be out soon. Thanks!
