Stuttering in new arenas since last patch

not sure if you guys care, but the new arenas ffa are stuttering quite hard for me. the latest ones with the blue interface are the worst. I could load up an older arena from my saved presets and it will run smoothly no problemo. also ranked, deathmatch 4v4, quickplay all work fine and smoothly. just the newest arenas and only since the last patch. but maybe the “while you wait” patch fill fix it. I suspect the interface of the left side indicating the dmg/min is the reason for it, but could be something else. just wanted to share because the option to play them while waiting for ranked is about to go live.
