Rockstar Games’ servers have been under heavy fire from massive DDoS attacks in recent days, causing widespread login and connectivity issues for players of GTA Online. These attacks come in the wake of Rockstar’s recent implementation of BattlEye, a new anti-cheat system designed to crack down on in-game cheating, sparking backlash from a segment of the player base. Protesters, unhappy with the new system, have resorted to using distributed denial-of-service (DDoS) attacks to disrupt the servers, escalating tensions between the gaming giant and its community.
I’m unsure if GTA V was ever Steamdeck Certified, but I imagine it might have to do with that. They may only offer this for games they said were certified and the devs broke it after the fact. I know Monster Hunter was.
