I as well would like to know if Rebar can be enabled some how in Windows 11, I already have an ARC GPU and the Arc software says that resizable bar is enabled and turned on, but the device manager properties as well as GPU-Z state that it is disabled… not sure what to trust but there is definitely a drop in performance with an Arc GPU in an eGPU over the previous 3060 I had in there and it’s very frustrating.
