I tried the config, and it works. I usually play on mid settings with 30 FPS. After using the config, the game became as smooth as it can be. Now, I play with the highest settings and 40 FPS. 40 FPS to let my phone cool down. I haven't faced any trouble yet. I saw some bad reviews, and I think you should read the instructions carefully. For the devs, could you also bring config for Wuthering Wave, please.

been using it for some years its a good app to optimize game performance especially fps of the game but one thing i've just noticed in 6.3 update of genshin impact was when i change to vulkan graphics it doesnt change anymore i opened the game and the game's graphics api says its opengl so i tried again but its the same, i hope this bug will be fixed, but anyways thankyou.

this app is AMAZING GURLL. so i downloaded this app mainly for trying out new feature in genshin (graphic api). my phpne supports vulkan so i give a try. unfortunately, changing to vulkan makes my genshin laggy. BUT, using opengl with all cores enabled instead makes my genshin run SMOOTHLY. i mean the fps is stable at FONTAINE when usually its kinda unstable. thank you for your hard work. i appreciate it <3
