My experimentation with gaming using Steam had gone just fine, as well. But I hear it all the time, that Linux and gaming have issues. My response to them is pretty much that I don’t care. I don’t use Linux for gaming. Gaming isn’t my thing. To me, gamers and their needs are completely unimportant, as the pass time is just a waste.
Niche, huh? Linux dang near runs the world. Not being a primary gaming platform does not make it niche.
