Yeast is an opportunistic pathogen that will secrete toxins. The reason that you don’t get sick when eating bread and stuff is because the yeast dies when you cook it, preventing infection. Although, I’m pretty sure you’ll be fine if you ate live yeast, because your stomach would kill them, also preventing an infection.
It should support DLSS unless you have an older video card, which the drivers don’t work well with. I heard the newer Nvidia cards work better though. Of course, is all up to you whether you like it or not, so just try out Linux and see. If you don’t like it just reinstall Windows. Make a recovery Windows USB beforehand though, makes it easier to reinstall.
