@G30FF Thank you :)

@redneck hello. This is the RetroPie forum. RetroPie (https://retropie.org.uk) is a collection of shell scripts to assist with downloading, installing, and configuring of various different front-end and emulator softwares to turn your Raspberry Pi or PC running Linux into a retro gaming machine.

Perhaps you were looking for the Raspberry Pi forums?

@Mrakobijes said in trying to use KMS driver yields no composite video output (Raspberry Pi 4):

dtoverlay-vc4-kms-v3d-pi4,composite=1

This looks like a mis-spelling, it should be just:

dtoverlay=vc4-kms-v3d,composite=1

and you should start with stock config.txt, instead of the one you're using, which has too many overclocking options which may conflict.

Note that this configuration is not fully supported by RetroPie yet and for the KMS driver is recommended to use an up-to-date Linux kernel/firmware.

You

But nuts is pretty much where my head is at on this, yeah.

Btw I was assuming you were using the lr-fuse core. If using standalone fuse, then my advice won't help. Please let us know which emulator if you're not using the libretro core.

@lfcfooty
@DanTarl solution didnt worket?

@classicgmr definitely improved

@mitu I have a 1440p monitor and it doesn't work
Should I also add those lines?

Thanks to both of you! I have something like 90% of my stuff copied over and now just have to go through to tweak some of my custom settings.

@kingcosmuder thats all i got running the command however i tired some dreamcast using redream and both games i tried, sonic adventure and marvel vs capcom 2 both ran 60 fps consistently so i believe its working now

@crush ok, thanks.

@themazingness
Hi!
Just for log information, I had this same problem today and I solved using this:

make a copy of /etc/network/interfaces
sudo cp /etc/network/interfaces /etc/network/interfaces.old

append to the file /etc/network/interfaces
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

enable the wpa_supplicant service and restart
sudo systemctl enable wpa_supplicant.service
sudo systemctl restart wpa_supplicant

*restart the system
sudo reboot now

@omission229 No, sorry, otherwise I would have said so.

Oh, right. Sorry I forgot .-.

@quicksilver dont quote me on this, but yes i UPS will help level the spikes. a surge might, but i think the choke if there is one on a surge protector will not be that big compared to a UPS

Sorry to bring up an older thread, but much of the information here is highly inaccurate and is mostly due to people buying cheap flash drives and SD cards which are very hit-and-miss. I've tested in my Raspberry Pi 4b 4gb a Samsung EVO Select 64gb Micro SD, Sandisk Ultra 16gb Micro SD, and Kingston Canvas Go Plus 64gb Micro SD and they don't come anywhere near the performance of my Sandisk Extreme 3.0 16gb USB flash drive.

Here is the Samsung EVO 64gb Benchmarks: https://pibenchmarks.com/benchmark/51099
And here is the Sandisk Extreme 3.0 (for some reason it was identified improperly by the benchmark program. This doesn't change the performance numbers): https://pibenchmarks.com/benchmark/51100

Here is a link to the actual drive. https://www.amazon.com/SanDisk-Extreme-Flash-Drive-SDCZ80-016G-GAM46/dp/B00KT7DOR0

Booting from the Samsung Evo Select takes about 10 seconds longer than the Sandisk Extreme 3.0 usb stick.

That benchmark website pibenchmarks.com has tons of information on what drives are fast and what isn't. My USB 3.0 Samsung FIT drive is absolute hot garbage when running on a Pi 4. The fastest MicroSD cards do about 1700 points on the benchmark, There are USB sticks that score as high as 5,000 points. Then there are M.2 drives using USB 3 adapters which score over 10,000 points. Where USB Flash sticks and actual SSD/m.2 drives really excel is in the 4k random read/write tests which are the most important thing when it comes to performance.

@rva-818x-laystar The only game i found running better than its DC counterpart is Marvel VS Capcom 2
the rest either runs the same or worse in the case of Dead Or Alive 2

@phos
Did you get anywhere with this in the end?

@mitu said in Screen tearing in pi 4:

Try using fbi, it's an image viewer that works on the console also.

Thanks that looks promising. I’ll have to see if there’s a way to control which display it outputs to.
