For pubg specifically,try to use X mode always,also use hardcore tuning to overclock the chip and make it give out better results in game
Just saying,you can play this game on ultra HD with water reflections on and on a stable 90 FPS with 20 ms stable
Don't worry,your phone probably is fine and some options hold it back,care to share some screenshots of your X mode settings and your battery optimization settings? That play quite a roll in performance
You're not sharing your settings. How do we know you're not using resource-demanding options like UHD or whatever? I play on 144hz/Smooth/90 fps/Ultra Audio and even with 720p recording enabled and i still get no stuttering, maybe an occasional "enemy rendering" type of stuttering but that's it, not a big deal. No X-mode required and no Aero cooler too. If you're playing on the lowest configuration and still experience stuttering, then you need to either repair PUBGM or do a factory reset. If neither works, then you have faulty hardware, my friend.
My settings this.
Share my setting. Look at please
I can't understand this language but game genie aside, your PUBG shouldn't even be having any stuttering at that configuration even without turning on x mode. Unless you have the strix version which has the weaker, un-overclocked SD865, your device shouldn't have any problems with maintaining 90 fps. If you don't mind, do a factory reset, reinstall pubg and see if it'll run better. If it still won't, then there's something wrong with your hardware.
Stop spreading nonsense. Even the sd non plus can handle pubg
Go factory reset your device it might fix it if not there might be a problem with the cpu.
Make the language English and then I'll help you,but still I don't understand your frame drops
I also faced the same problem when I purchased the phone it worked very well during first two days then after I started facing the frame drop issue in game.could anyone suggest me a solution to solve this.please help mee.
