GTA 5 Loses Steam Deck Verification as Rockstar Claims Valve's Handheld Does Not Support Anti-Cheating Tech
"Steam Deck does not support BattlEye for GTA Online. You will be able to play GTA V Story Mode but unable to play GTA Online," Rockstar writes. "GTA V and GTA Online are not officially supported on Steam Deck and all technical support questions should be directed to Valve’s Steam Deck support content and community."
