I have a Xiaomi Pocophone F1. It has a Snapdragon 845 and also an octa-core. Its has 6GB of RAM and 64GB ROM. I installed and ran the benchmark test 3 time and the lowest realtick I got is around 650. I changed the OS from MIUI to stock android 10 via the XDA forum’s instructions. I changed it because MIUI has a bunch of restrictions. I tried running exagear on my phone to play HOMM3 and it runs wonderfully without any slow ups but I won’t be using it because of it’s obscure touch setup(and the app is abandoned). I tried your advice but still nothing has changed, the cpu that shows in windows 95 is still intel petium 70 mhz which is way low to what I need. I just really need to change the CPU I think but how? I hope you can help me
