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.
I have the same laptop, running Garuda. As someone else said, definitely watch the temps. Mine can hit 90 degrees easily. It seriously is worth looking into undervolting the GPU. I haven’t done it yet because I’m the odd one out and am very hesitant to mess with something that is working at all.
My CPU got up to 93C and GPU got to 85C when use ultra settings and unlock framerate, I’m might look into undervolting in the future but I might have some problems because I never done that in Linux.
Yeah, the performance seems fine, but under load touch the area near the hinge. The plastic is warm, almost hit on mine.
