This shows you're currently using 1080p - which the Pi4 should handle easily, so the slowdown is not from the video settings. What controller(s) are you using ? Does it happen when using just a keyboard to launch a game ?

Ok you may be on to something and initially I thought that might be the problem too since when the retroarch menu finally comes up or the game loads finally i see the little notification in the bottom left saying controller.. connected..

I have a SNES Classic 8bitbo controller. I've updated all the fw to the latest.

Testing just a keyboard with my bluetooth controllers not connected it works fine.. WTH, any ideas?

Odd part is as soon as I updated the fw on my 8bitdo controllers a week ago it worked fine one time so i thought it was that, but then behavior went back to normal the next time i launched a game. Now testing again just the keyboard and it working I think something is going on here but no idea what...

My exact controllers (2 paired):

We've seen this issues with 'slow' controller initialization when the controller is in XInput mode. Try running the controller in Switch or Android mode - you'll have to re-pair it in and re-configure it EmulationStation after you change the pairing mode.

You might be a life saver! I will try that and report back later tonight. I do have it in x-input mode atm so there is hope. I thought your documentation said to use that but could be wrong.

I think we are fixed! Tested multiple times and the timing it much better. It still seems longer that what my arcade cab does with same setup with the exception being the controllers. Right now its about a 7 second wait after the launch screen goes away. Prior it was about a minute :)

Thank you!

@Lesezeichen Copy the topic link, then in the new topic, you insert a link to this topic.

@ej_424 Yep, if I'd seen this topic earlier, I could have answered this immediately. :) I had the same issue a while ago with my SN30 Pro+. Setting it to Direct Input mode solved the issue.

By the way, is there any more elegant way to limit the resolution than hard coding the resolution to 1080p? I seem to remember you can limit the pixel clock instead, but I haven't tried it. Also, given the performance issues with 4K, wouldn't it be better to have RetroPie be limited to 1080p max out of the box, with an easy way to enable 4K if the user wishes?

Yes, it's possible, though this will disable the 4k video modes completely.

This is exactly what the hdmi_mode/hdmi_group settings do - set 1080p video mode by default, with the ability to choose 4k via runcommand (though performance will not be great). Kodi/Pixel desktop would still be able to use those modes for 4k HEVC movies/normal desktop.

Unfortunately there isn't a way to configure the video so that 'if 4k is available, use 1080p by default', so instead of forcing 1080p by default for all configurations, it's something that the user must configure after installation.
