Slowdown on Linux anyone else or just me?

It's 30fps lowest and varies a little up to say 40. I've struggled through the first "intro/training" level to the Chozo Ruins the frame rate seems to jump around a lot (never below 30 and can be as high as 60 in small rooms with no actors) so this is looking like it's something to do more with the intro video that plays in the background of the opening of the game? I might surrender and install Windows to see if that makes any odds when I get a chance.
