yes, I'm also having problems with games. I just said that in addition to the problem in games, there is also the problem of mirroring
Ok I was unaware of any problems with mirroring, never tried it. Let's hope there can be a fix for both issues. I mostly game and have never even tried the mirroring so I wouldn't have guessed it.

I tested a new pixel experience plus rom.This error appeared. It doesn't even open the games No Google Play Store Key (No OBB found and no store key)

I had the same issue with games, I tried smartpack kernel manager to put the gpu on performance mode and that solved it
I'm guessing that'll require root? If I needed to root my device as it is right now will all I have to do is flash magisk then factory reset? Or flash magisk without reset? I unlocked my bootloader, installed twrp, installed arrows os 12.1 using the required method, I'm on arrow recovery.

It requires root. You have to install magisk via qfil.

You made some wrong steps.
First, if you can enter ArrowOS, it means the rom is already installed. You don't need to reinstall it via Arrow recovery. Remember the rom is always flashed to the inactive slot.
Second, if you want to have Magisk, just go to Arrow recovery and apply update, select Magisk zip file.

You said about boot_b kernel patched. Where does it come from? If you patched stock boot.img, it won't work with custom rom.

Get back to your current situation. My assumption is your TWRP is at slot A. After you installed the rom in TWRP, the ArrowOS was installed in slot B. You rebooted to Arrow Recovery (slot B) and flashed ArrowOS again, it was installed to slot A. And now you have ArrowOS in both slots. If you didn't switch slot from Arrow recovery, you are still in slot B.
To resolve this issue, I think you will need to flash Arrow boot.img to your active slot (Slot B I guess)
Try this one: https://www.androidfilehost.com/?fid=7161016148664837147
How do you flash this file? Using arrow recovery I don't see the file. Use adb? I cant boot to arrow os in slot b after I install magisk.

You need to get your boot file using qfil, patch it with magisk then in qfil replace your current boot img with the patched one, atleast that's how i did it
Thank you, it worked rooted and on arrows os 12.1. so now back to the gaming performance, I installed smart pack and have been browsing through the settings. Did you change the gpu governor to performance and that stopped the hitching and crashing? What exactly did you do to fix?

I only changed the gpu governor to performance and the crashes and stutter were gone

I have successfully installed this ROM to my LG G8, but it seems that it does not have root permission

In qfil back up the boot slot you are using whether it's a or b, send it to your device, install magisk apk, patch boot img using magisk, go back to qfil and replace your original boot with the magisk patched version. Reboot and you'll have root.

    Hi all - first, about the download link, it is AndroidFileHost issue and I have no way to make it work. I just create MegaDrive account for new upcoming builds. The alphaplus test build is already uploaded into it.
    Second, perhaps my kernel is causing the issues. This weekend I will try to use kernel source from Markus (v50 dev) to see if these issues still happen or not.

    If you guys still want to use my ROM, please be patient. I still have my own life and this rom was created for my personal use initially. Because there are no devs for G8, I decided to share it here and didn't expect any donation. I'm really new to Android rom development and ArrowOS is my very first rom which I have ever built.

    Happy new year all! New builds are uploaded into Megadrive: https://mega.nz/folder/iQFXCSAa#N_SqYZA1TptEJVyPVg5iXw

    Michael Smirnov helps me to test alphaplus build and he says its battery is better now.

    Two new builds are uploaded. Don't expect battery draing is fixed. I'm still need to investigate it.

    I found the developer in the telegram channel https://t.me/v50thinq and asked him to update the latest firmware version. Here is the link, lets download, install and test))) https://mega.nz/folder/XEEVDCIR#QtlnMaX2mq9juB8GGyoUHw

    Bluetooth music now works for me, DAC works too. The battery drain i began to be tested.
    The speaker with phoinecall is not working properly. The interlocutor hears himself during a telephone conversation. Ie noise reduction does not work. Check out how you are with that.

    Otherwise, everything is perfect!
