Xbox Series X runs the Modern Warfare 4 beta most consistently, with its 60Hz mode holding a near-locked 60FPS and its 120Hz mode generally landing between 110FPS and 120FPS in multiplayer.
Dynamic 4K is the target on Series X, but internal resolutions appear closer to 1440p at 60Hz and around 1080p at 120Hz; campaign performance in 120Hz mode sits nearer 80FPS to 90FPS.
Xbox Series S targets dynamic 1440p across both modes, yet internal resolution ranges are much lower—about 1080p-1206p at 60Hz and 576p-1080p at 120Hz—with frame rates swinging more sharply.
Series S multiplayer can hit 120FPS but also fall to 70FPS in 120Hz mode, while 60Hz mode drops to roughly 40FPS on respawns; its campaign holds closer to 60FPS.
August 25 marks the end of the first beta weekend, with a second test scheduled for August 28 to September 1 ahead of the full release on October 23, 2026.
