Hello, I was checking FPS on Asus ROG 2 and it was 30. Are there any plans to increase that because there are devices that are capable of 90 or 120 FPS?
Cheers!
Just locate your options.txt in android, data, hearthstone and at the end add a line “targetframerate=60” (without “” and type the value you want), add another line with “vsync=0”, done!
Its running super smooth at 60, but the patch destroyed the performance so be aware that it stutters really hard sometimes until they fixed it. Happens on my Note 9 and Tab S6 with Snapdragon 855.
Great will try that out 
I have tried your suggestion but it says permission denied 
tried with text editor…
Just cut out the .txt file to any other folder outside of the android data file, for example to downloads. Change it there, save it and copy it back to the folder you cut it out.
