What are the best Marathon settings for PC? Bungie's new extraction PvP shooter is one stylish addition to the multiplayer fps space, and thankfully, it's not too demanding to run. We've fired up the early Marathon Server Slam - running until March 2 - and tested the game to find the best graphics and other settings to optimize this title for a typical mid-range PC. It's still too early to tell if Marathon will end up being one of the best FPS games when the full Marathon release date rolls around on March 6. However, when the Marathon system requirements dropped, it was clear this wasn't going to be the next Crysis, when it came to GPU demands, so the best graphics card wasn't going to be a requirement. Steam Deck users are out of luck, for now, though.
