Combat visual effects

Last leagues i have noticed more and more that the game become "unreadable" during any fights on the e screen.

Visual effects, such as fire/lightning particles, are not transparent and with all those monster group boost and lots of hits it become a messy mishmash.
It ts barely distinguishable anything except lifebars. Even when i play it alone and without mass attacks.

Most battles looks like this:


From league to league effects become brighter, consecrated ground for example. It makes game very hard to look at.

Another thing is FPS drops because of it.

Synthesis monsters fire lots of bright projectiles which lower my fps to 5-15 in even small fights.(gtx 1060)
A year ago the game ran perfect without any fps drops at high settings. Currently im using all on low and still get freezed almost every monster pack.
