Frame rate issue
I'm using a redmi 14 pro Android having mediatek helio g100 ultra chipset. Still high frame rate option is unavailable in game..this is quite unnatural. I'm getting 60 fps in all other games i'm playing..
In the first box, where it says graphics select medium. You will then be able to select high frame rate. If you select power saver, high frame rate is not available.
