I put around 16 hours into Battlefield 6 over the weekend and mostly enjoyed it.
I do feel they need to crack down on the cheating more, despite reading somewhere that they already stopped more than 300K cheating attempts during the open beta, which is insane! I spawned on a teammate on Sunday and ended up under some concrete stairs (clipped), where he was just shooting people from below. I had wondered why I was getting killed on occasion with no indication of where the enemy was.
My Ryzen 5800X3D and Radeon RX 9070 XT Reaper (-75mV undervolt) ran it very well. 80-100 fps depending on the map and conditions at 3840x1600 (38-inch ultrawide) on Ultra settings. Enabling FSR Quality (3.1 afaik) took the framerate up to 120-140 fps and that's probably how I'd choose to play if I decide to buy it.
Still undecided on a purchase with Borderlands 4 coming out soon too, as I'm a big fan of the Borderlands games (but not the terrible movie).
