Having gone back to my old pre 5.4 build Retropie I found I needed to downgrade my Kernel due to glitching graphics. Since I have done this I am convinced that Retropie, especially N64 is still running slightly smoother than it did before.

@mitu I tried the runahead out and it was great! Thanks all!

@Unknown Even if it was supported, a pi4 will never run most games at a playable speed. Buy a used wii with gc support from ebay or a shop. It's sometimes cheaper than a pi4.

If you have a 4k tv/monitor, then use raspi-config and change your default video resolution to 1080p.

@TeeEl Sorry to hear that. My arcade cabinet has a 32" tv, but the problem started for me a few months back. But I couldn't pinpoint exactly what caused the change (I already had a similar post about it). Thankfully for this post, I was able to find an option that worked for me. I hope you do too!

@dankcushions @mitu Nevermind, I figured out the problem. I didn't configure it right. My apologies for bumping posts.

Pi4's Vulkan driver has been merged into the Mesa repo. https://www.raspberrypi.org/blog/vulkan-update-merged-to-mesa/

@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!

@MegaTimX said in Rpi 4, No display on my 3440x1440 monitor, works perfectly on my 4k TV.:

Hopefully in a future update HDMI support for this monitor(resolution?aspect ratio?) for the Rpi4 will be added.

Unless someone reports it upstream, I don't think it will be magincally solved.
Someone reported something similar this last year and for them it has been solved with a firmware update, see https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=248037&start=25.

If the recommendations in that topic won't solve your issue, then I suggest replying to that topic and adding your own monitor EDID for the RPT engineers to check it.

Many 3D arcade titles still struggle on the pi 4. Unfortunately I think we are stuck using the ports for virtua racing. The saturn port is closest to the arcade version and runs pretty good using lr-yabasanshiro. You can get the experimental script module for it here: https://github.com/RetroPie/RetroPie-Setup/pull/3132 (it is not officially a part of retropie yet but you can test it out like I have been).

@Hillbilly The page you have linked for your display is their whole lineup so I'm not sure which one you have, but judging by your config it should be an easy fix. I have a similar display that they give me almost identical settings with.

The main issue is that you've been given a bunch of text to copy and paste without any explanation from the supplier. To top it off, what they've given you is erroneous and based on an old config. This is a great resource for figuring things out and checking whether your /boot/config.txt settings are valid and have the proper syntax: https://www.raspberrypi.org/documentation/configuration/config-txt/README.md . If you bought it off a place like Amazon, there's a good chance someone has posted the correct options in their review.

Long story short though, you should replace the last section that was added after overscan_scale=1 with:
hdmi_group = 2
hdmi_mode = 87
hdmi_cvt=1024 600 60 6 0 0 0
hdmi_drive = 2

This will properly set the resolution to the display if it indeed the correct resolution by putting the equal signs next to cvt and actually setting the option. group 2, mode 87 lets you set a custom CVT that is 1024x600 resolution @ 60 Hz with a 15:9 (6) aspect ratio and no margins (0), progressive (0), and normal blanking (0) described in https://www.raspberrypi.org/documentation/configuration/config-txt/video.md . I also find it good practice to put each option where they make sense only once so it's less confusing and doesn't cause frustration when you're changing one and then further down the same option is overriding your changes so I would recommend moving them back up into the config.txt to replace the others.

To remove the black bars, you can uncomment (remove the hashmark) from disable_overscan=1. You also more than likely won't need config_hdmi_boost=9 so you can probably comment that out.

Not super versed in audio troubleshooting. If sound is working in games, I would've thought it'd also be working in EmulationStation. Hopefully the previous mention of setting hdmi_drive to 2 will fix that. It's not making little clicks when you move around in the menus? Does changing it around from Auto, Headphones, and HDMI have any difference on whether you can change the volume? You might try using a keyboard to see if that helps or updating RetroPie through Setup.

Imagine you've tried all the Bluetooth options while getting Protocol not available? If you're trying to connect to speakers or headphones you'll probably have to follow a tutorial to add that functionality. I don't know if things have changed with the Pi 4, but I remember being rather frustrated when I finally got it to work and just started over with a new RetroPie image without it.

I hope at least the part explaining the config.txt options has been helpful to you.

@rubencg said in Have there been any news about Vulkan Drivers for the Pi4 since February?:

Pi4's Vulkan driver has been merged into the Mesa repo. https://www.raspberrypi.org/blog/vulkan-update-merged-to-mesa/

hmmm... wouldn't get your hopes up too high.

I compiled and installed using these instructions

then i tried some things

a self compiled version of ppsspp with vulkan support. conclusion: vulkan works, but framerate on vulkan lower than with opengl backend a self compiled version ofr retroarch with lr-mupen64plus-next with vulcan support. On the normal open gl renderer it works, but gives a segmentation fault on the angrylion vulkan rendererer a self compiled version of retroarch with lr-parallel: same segmentation fault on the same renderer

so apparently a lot of work to be done before we get benefits using vulkan....

@janderclander14

Thanks for the fps check.
For the sound, It depends, for some 2D games, the sound is not that bad (not far from a good experience).
In the Hash file , located in the BIOS/mame/hash folder , they commented slightly on the playability.
Some games are not playables even on both emulators.
I'm running Zool 2 or Bubsy at 49 FPS with Lr-Mess and 33 FPS with Lr- virtualjaguar (Big difference)

Yes I have a pi 4. I did manage to make some changes to the settings it was a challenge lol. I can change the internal Drastic views on a horizontal screen. But I want the whole screen rotated 90 degrees(vertical) so when I stack the screen top/bottom it uses up most of the viewing area. Here's what I would like to achieve on Drastic. This is what my lr-desmume looks like.

I've just had the exact same problem this morning and thought I was going mad!

This is actually a great feature as it provides further protection against guests inadvertantly entering it even after applying Kiosk mode.

Many thanks Mitu!

@Tieelo Did you fix the issue? I get the same error message trying to install from Extras.

@Rancid84 said in Pi 3 b to Pi 4 b:

I just bought a R4 and have an img from R3 downloaded from arcade punks. Are the previous comments still accurate to use this IMG from R3 over my R4?

Third party images are not supported. Do so at your own risk.

Weird. I tried this a while back and it didn't work. I was using my typical Logitech F310 and a Rock Candy Wired controller. (Granted that the rock candy controller would disconnect if you sneezed on it.) They didn't work together.
