Street Fighter 6 runs at 540p and upscales to 1080p with dlss docked.
"While our initial pixel counts of Street Fighter 6 during the Switch 2 Nintendo Direct reveal pointed to a native 1080p based on limited footage, the more recent Nintendo Treehouse feed shows a scale from a native 960x540 to a 1080p target using an AI upscaling method - with evidence suggesting Nvidia's DLSS based on this footage. Looking back, this 540p upscale appears to be in place in the original Direct footage as well. It's a remarkably clean scale in most shots, with the first few frames following a camera cut being one way to catch the base resolution from its docked mode play. We'll be sure to report back once we have more information."
