Don't know about present. Back when I worked with a version 2, Raspbian couldn't handle a 2560×1080 UltraWide without low frame rate with stuttering but ArchARM with Sway had no issues.
I would be suspicious of that being the display server as much as the OS, though... although, granted, I suppose it depends on what the fair basis is for comparison. A person could argue that "performance of the default graphical stack" is at least as important as "performance of a CPU-bound workload if you tune everything else".
