Oh fuck no. Definitely not. GTA 6 will be pushing even the PS5 to its limits 😂. So the Steam Deck doesn’t stand a chance…. Now the ASUS Rogue Ally or the Lenovo Legion Go? Yeah, that might be capable on medium to low settings. Most likely low settings more so.
I assume this was supposed to be a Steam Deck and it’s not? Better put in a complaint my guy. Get your money back to a RE-shipment!
