I have a Samsung Galaxy Tab s7 and play Hearthstone a lot. I'm surprised by the poor performance on this device. On my Pixel 5 it's flawless.
I edited the game's options.txt file to unlock 60 frames per second. However it hardly every keeps this and often drops and stutters. I used Samsung's Perf Z (within Game Plugins) to monitor the FPS as well as CPU and GPU usage and both the CPU and GPU are always less than 20%. How can I force it to use more power? I've tried the Game Booster Plus settings in Samsung such as 'Max FPS' but this doesn't seem to do anything.
