Windows 11 :/
Though heavily neutered, where even defender is disabled.
I boot CachyOS Linux with a lot of tuning (and some recent game testing). A linux gaming OS! I'm using Cachy like 95% of the time; I am not anti linux.
But honestly... It's just not worth a few lost features and performance hit over Windows for me, on top of the extra hassle. Its easier to just reboot. Maybe the experience is different on AMD GPUs, but I suspect Nvidia is at a disadvantage here.
This is on a desktop. Based on my experience with a RTX 2060 laptop I used to have, you also have the to deal with graphics switching, rendering on one device while displayong on another, and making sure your 1050 actually goes to sleep when not in use.
