I just got this laptop (Asus TUF A15 2021) today and it surprised me that everything works just fine out of the box on Vanilla Arch, except NVIDIA gpu I had to install it manually on battery power that’s why I enable powersaving mode. As for games performance it’s basically the same as windows no more no less.
Yeah, the performance seems fine, but under load touch the area near the hinge. The plastic is warm, almost hit on mine.
