I used GLTools, and a custom kernel with performance governor enabled. That was incredibly buggy and crash-prone though, so I reverted to a rooted stock kernel.
I’m getting about 550-600 realtics now.
Samsung’s kernel management is ridiculous, it keeps force downclocking the main core to 1.8 GHz instead of 2.7 GHz. No idea why they’re doing this, my cpu doesn’t heat up at all. ?♂️
