I'll try to SSH and confirm if the settings are correct. the recalbox OS runs normally, however, when retroarch runs it switches to 4k output. I can confirm the setting is set to the default value of 1080p.
On the plus side, Kodi seems to work well for videos up to 1080p as well, hdr10 works perfectly. I notice that 4k playback does not work well (likely will improve with drivers) as well, audio pass-through is intermittent in Kodi.
Other than that. it definitely feels faster than my RPI3 on loading and general interface browsing.
First, it's so great that you're providing feedback already! Thank you!!
Same as Luke, I too am quite interested in more details on this. The resolution outside of KODI has been locked at 1080p in all our testing. Can you please confirm what resolution (Xres x Yres) you're seeing retroarch change to, and specifically what emulator, core, and Rom you're testing?
I'm also interested in more detail on your 4k performance concern. Big Buck Bunny and LG HDR test vids both perform great in all our testing. So what are you testing with? What are you seeing the CPU % at? Are you playing off local media or over your network? (It's possible you'd experience a lag over network depending on file size). And are you doing anything else on the board at the same time, like transferring files or anything?
Once again, thanks for the feedback! The more detail the better!
Good evening,
All emulators that I have tested (GBA, SNES, and NES) are trying to run at native 4k resolution, which also, due to hardware limitations, runs as 30fps which is my main concern. I can provide a screenshot tomorrow to confirm this if you would like.
The 4k file in question is a 4k raw rip of black panther, no other operations were running at the same time. I will attempt to grab more information tomorrow on cpu usage. I also noticed that running the web interface does seem to eat up a core of processing. The file was running off of my Nas on a wired connection, using UPNP to send the file. It is possible it could be due to the size of the file. I will see if I can try a less complex 4k UHD file and report back.
For 4K movie which is 24 frames per second, better set the video output to 4Kp24 for smooth video playback.
