Teslagrad looks incredible, but it's not optimised for Exynos s21 devices (s21+) at all. I can't get past the first area thanks to single digit frame rates. Using Samsung's tools to max performance doesn't improve the experience at all. I'm hoping for a patch, especially as I'm way outside the refund window now, and this game looks great, but I'm not expecting much as it looks like this isn't a new issue. DO NOT BUY IF YOU HAVE AN EXYNOS DEVICE.
