b4nnyGo watch WarOwl or Greekgod or any new TF2 player playing competitive mode for the first time. They didn't care nor notice any issues with the enforced graphics settings. Your perspective is biased because you are too attached to your FPS configs. Level playing field, standardization and accessibility is a necessity for the integrity of the competitive mode long term. That said, they should definitely add as many commands/settings as possible to the options menus so that FPS config level graphics can still be achieved while maintaining fairness.
warowl's mic and headphones together cost more than my computer b4nny. You cannot expect everyone to have top of the line systems especially considering the age of this game.
