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.

This is a surprisingly good optimizer. I wasn't expecting it to work. But, it proved me wrong. Although, it is still a bit laggy, that is fine. As long as it's less laggy. As long as you read the instructions well, it should work. And also a tip: to find out what your SoC is, download CPU-Z. Downloading this won't instantly make your game lag free, it just lessens the lag. It all comes down to whether you have a good phone.

S22 Ultra user here. Crashes when saving config, Android 12. Maybe its Samsungs fault and not the Android versions fault? I dunno. Anyway, whether this works or not, I don't know. Took a screenshot with and without vulkan despite it crashing and saw no graphical changes. But hey, It does SEEM to run better, so I guess its doing something?

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?

Huge improvement to game performance I check every core as big core (according to SoC I have 2 big and 6 little) after trying to config this file several time I noticed that the game is running more smoothly with higher amount of big core getting checked, I guess the game is running more heavily on big core and probably will consume more power. Vulkan is not working on my phone it crashed my game after several minutes.

Does it's job. Using on Galaxy Note 10, it drastically lowers the heating issue in 60 fps. Notable differences in gameplay But as of now, it's not working. After 4.1, the game layout is somehow bugged and isn't fixing by any native means. Asking the devs to fix the bug through manual checkup

This app is good. Easy to config and edit my existing hardware_model_config.json myself comparing the original and edited code using text editor. Tested on my Helio P23 (Mali-G71) and it works with Vulkan 1.0 in login screen, but it crashed during loading, considering as "Out of Memory" because my RAM is 3 GB. This tuner is for testing purposes only not for daily usage.
