Mac Client Scourge League Performances

Hi,

after playing the Endless Delve League, in which the performances were absolutely fine, I came back to the Scourge League.

Instantly crashes started again, most of the time from the third map on I have all blurry content(T13+) and almost every "new" boss I fight has invisible attack.

Also the CPU is used still at full capacity and the GPU can't be used at all.

Is there any plan on fixing the issues or we are just waiting the official release of the Mac Client?

Cheers
