Correction: It was marketed as a proper power supply, but without a USB-C tester, can't verify if it's a charger or a power supply.

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.

@Yobiwan We don't support 3rd party images - wrong/broken configuration is one of the many reasons.

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

@dankcushions said in Vulkan and Hardware video drivers: you can compile the VC4 rpi driver if you want - give it a go: https://github.com/Yours3lf/rpi-vk-driver you would need to change retropie build scripts to use it, and i anticipate more or less nothing 3d will work since the hardware isn't vulkan compliant, and so the driver is missing features: https://github.com/Yours3lf/rpi-vk-driver/wiki/FAQ Oh. Lol. To be fair the developer says there that it isn't really a Vulkan driver: "RPi-VK-Driver is a low level GPU driver for the Broadcom Videocore IV GPU that implements a subset of the Vulkan (registered trademark of The Khronos Group) standard. The implementation is not conformant to the standard (therefore it cannot be called a Vulkan driver, officially) but tries to follow it as closely as the hardware allows for it. Compared to the available OpenGL drivers it offers superb speed including precise and predictable memory management and multi-threaded command submission. It also offers a wider feature set such as MSAA support, low level assembly shaders and performance counters. On the other hand it currently does not support GLSL shaders."

@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.

@mitu Cheers.

@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 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!

@saccublenda Thank you very much. I was just too dump to find it on my own in the first place. But with your script I get the same Error as Gamer-D. I am also on RPI4 with RetroPie v4.6

You do not need to restore your full backup from mitu's Step 0. That's your emergency fallback in case the whole thing goes wrong. You can use this image to reflash your SD card to its original state and start over. Steps 1-3 are the actual migration process.
