Anybody else having trouble with the PC version lately?

I haven’t played in a while, since around the time Shadow Lords was new. Yesterday I launched the game and while it SEEMS to play fine, eventually the fight scenes slow to a crawl. Especially around the time I use shadow moves. This is against the CPU so I know it’s not connection based.

It used to work fine through all of Season 2 and 3, but now it’s really lagging hard.
