@mitu I was just messing around with all of this. I don't have a RP4 yet, but plan to get one. I just wanted to get familiar with the different gaming-centric OSes before I got mine. I'm running this on a laptop that's running Windows 10. I need the ability to have Windows 10 running while I play around with this RP and emu stuff for the time-being. Using VirtualBox gives me that ability. I checked the '3D Acceleration' checkbox and now RetroPie runs. However it's really slow and beyond the configuration menu, I don't see anything else. I've got a VM that only loads an SD card (no 'host' VM OS) of another gaming front-end and the speed of it is great. I'm guessing the slowness has to do with running a system in a system in a VM (or something like that). That's cool. I just wanted to see it.

@Hex @mitu For me, the power saving mode was disabled by default on 4.6.1 on a Pi4, I turned it on to Enhanced and the CPU usage dropped instantly to 0.3 as before. Maybe it needs to be reactivated by default?
Thanks for the explanation!

@dankcushions said in Any Difference in performance using 0/1 img on Pi 3B+:

another issue is compiler flags. the 0/1 have a different generation of ARM cpu, without some of the features of the 2/3, so they have binaries compiled without these features that would presumably run less efficiently on a 2/3 than with the right flags.

That is perhaps the strongest argument to use the correct image for your device. For example, the Raspberry Pi 0/1 does not support NEON instructions, which are used by many emulators for speed. The Raspberry Pi 2/3 does have NEON and also have a different processor with faster instructions. All of that can only be taken advantage of if the binaries are compiled for them. Running a RPI0/1 image on an RPI2/3 basically does not take advantage of any of these optimisations and will just underuse the better aspects of these devices.

@drake999 said in EmulationStation Consuming 65% CPU on Idle:

I'm finding that the EmulationStation process is consistently consuming about 65% of the CPU resources while idle on a stationary menu screen.

With or without videos? If the latter, did you enable the OMX player in Other Settings of ES' Main Menu?
