I'm on Realme V5 and there really isn't much improvement I can see. Visuals are still buggy as hell and turning Vulkan on basically makes the game s*** on it self. I have 6gb ram so there's some leeway but it does crash when it is turned on. Can't even finish the loading screen then shuts down. Still, the config file is easy to configure. Though accessing Android/data is a pain 'cause Android 11. Xplore helps alot. I wonder if there's a way to see more improvements?

It does improve the performance of the game even with medium graphics. It used to run at 10 fps (I Think) when I'm in Sumeru, the new region, but after applying 4 small and 4 big cores, it runs on like 30-40fps! 50 fps in Monstadt though. What I'm concerned is that it might be bannable in the future. Very risky but I guess that's one way to end your addiction to video games.

Edit; I'm not sure what the play store reports my device as, but it's a Nintendo Switch running Android 9. The Tegra x1 chipset on this device to my knowledge only has 4 big cores. Tegra devices have a unique bug where the ground is glowing brightly, I was hoping forcing Vulkan would clear this up. If I ever get it functioning I'll update this again with results. Could you point me to the location of the config file, assuming it's still there after the update.

ah I see, for low ram devices I recommend setting up atleast 2GB swap. Vulkan tends to use more ram than OpenGL due to old buggy unity engine. Monitor the process with htop and make sure there are no OOM issues. You must dedicate atleast 1 core as "little". The file is hardware_model_config.json, layout literally exact same as the app.
