Unfortunately, i have switched between all RHI types and have seen no difference.
One thing I noticed, after running the 5.3 editor on and off for days. Sometimes I would have a better frame rate with pretty much the same scene than other days. I always check my task manager processes. Iāve noticed multiple dormant UE.exe processes running pulling 4GB of memory, pretty much every time I start the editor. Closing those processes brings my fps up from sub 30 to 120+ on a pretty demanding project. May not help your situations, but works for me.

Is it possible that the issue is at windows?maybe windows didnāt realize that unreal is doing heavy thingsā¦so it didnāt give enough power to run unreal or something like that. 
. I used to encounter similar issue with playing some games. Iām not an expert.so whenever I encounter problems I always tend to reinstall windows .
Reopen.reinstall.reboot.they re all I can do.if they donāt work.I would very frustrate

Thanks for the reply! Yes that hapens to me sometimes too and i keep an eye on task manager. Unfortunately the issue occurs when i am only running a single instance in task manager.
I wonder sometimes if this is probably right. I wonder if there is just a setting somewhere that would make this the case? I might do a little more windows troubleshooting surrounding unreal. My other games/apps get astounding fps at max settings so maybe there is a hitch in the OS somewhere.
