Just finished playing a game and I noticed that every time the enemy Karthus used his Ultimate, my screen would skip some frames. I'd drop from a stable 60FPS to about 10-20 and then it'd go back to normal after the Ultimate ended.

Has anyone else been seeing this? O_O

This happens to me all the time. Nothing fixes it, not even going to lowest settings.

Also happened with me when I had a Le Blanc in my team, whenever the camera hovered over her, the FPS would drop.

It's happened with other champions as well, I've heard someone say that Zyra's E caused some lag lately too.

His ulti has always lagged me, glad I'm not the only one. Vayne's ulti has been lagging me too since the new patch. </3

had the same issue with karthus ult... dropped from 30 fps to not being able to move or use abilities for 3 or 4 seconds... and then my game would catch back up... but during team fight, at that point its over.

Add Malzahar and Vladimir to that list while you're at it...

Just happened to me too. It's definitely new since the patch. Never seen a fps drop like that before.

My fps drops like a brick when Karthus ults.

mine was as of today as well. just to clarify

I am also experiencing this issue since patch, would like a fix thanks
