The visual effects need to be seriously scaled back

When in a full party there is so much going on the screen turns to a blur.
Some boss mechanics and abilities can't even be seen.

This is especially prevelant in the Jamanra boss fight in Act 2 whose Wind phase can't even be seen, from how deteriorated the visual quality gets.

I'm running a fairly high end PC and exceed the system recommended requirements and this remains an issue.
