What are you on about? DRM is up to the developer, and while steam does use some resources it's not enough to impact performance. And no, it's a launcher, you use it when playing steam games or non steam games with steam overlay and controller support. See steam has this whole overlay system with a shit load of features from note taking to community walkthroughs, robust multiplayer support through the friends system, a whole ass chat client, and did I mention the incredibly robust controller support with exceptional customization features? I literally have to run three or four different pieces of software just to do what steam can do out of the box. As for the DRM free bit I think you're thinking of gog's offline installers. Their licensing language is the same as steams. But yes gog makes an offline installer available for all their games, they're the only game in town that does though so they're more exception than rule. I dunno why you have a hate boner for steam but it's literally the only launcher with features that I use outside of open launcher -> open game. Hell it even has a frame limiter. I can use rewasd and ds4windows with rtss and still need to run another launcher, or I can just run steam which can do all that stuff itself. What aren't you getting about the fact that steam does a shit load of things beyond letting you buy and launch a game, and all those things are why people like steam?
