Why is my RPi4 much much slower than my RPi3?
-
Yesterday, mainly as a test run, I installed Retropie as a fresh install on my Pi 3b with a 32GB memory card. Everything went smoothly, the controllers configured straight away, and when I installed all the optional and experimental emulators (from precompiled binaries) it did the whole lot in about 20 minutes. They all seemed to work fine.
Today I installed the same version of Retropie (4.7.1) on a brand-new 8GB Pi 4 with a 256GB Samsung memory card. Configuring the controllers was painfully slow, taking several seconds to recognise any button press. And installing the optional and experimental emus, again from the binaries, is now running at over 12 hours and still going.
(It's finished the optionals and is somewhere through the experimentals, can't really tell how far.)
Is there any reason this should be the case? I'd rather assumed the 4 was a more powerful machine than the 3.

Because you are probably still running it at 4K. You need to set the resolution 1080p and not 4K.

@thorr69 I don't think it can be that, because when I was setting up the controllers it was running in a REALLY crappy resolution. After that I set it to 1920x1080x60 (same as the 3b) and if anything it speeded up.

Sigh. 24 hours later everything is installed, it's still sluggish, and more to the point absolutely nothing works. Every game just crashes straight back to ES :(
-
@thorr69 Okay, I'm now reasonably sure that I have a duff SD card.
-
@superfella Seems like that's the case. That's a bummer.

@thorr69 TBH it's probably the best-case scenario. It's brand new and I should be able to get a refund, and better that than the Pi being knackered or unable to run Retropie :)
