Yeah, should be this one: https://www.gsmarena.com/acer_liquid_z530-7526.php
I managed to squeeze some 1800 realtics out of my Note 2’s 1.6 GHz Exynos chipset a couple of years ago, which should be just barely enough. What you can try is activate performance governor. You need to be rooted for that, though, which will void your warranty, and is potentially dangerous. Maybe if you can get somewhere round 2000 realitcs stable, you might be able to play the game.
