I wouldn't say "smoothly" at all. You know how they fixed it? By f$@%ing the frame-rate of plug-ins. If you load up an EQ and turn on the analyzer, set the decay to 24 dB/s, it's choppy as hell now. Seems to me like they did this in a hurry. At least it's responsive again..
Those were exactly my first thoughts, a quick & dirty fix. On an empty project after putting three or so insert effects on a track, I am seeing a huge drop in frame rate on the EQ plugin when dragging the bands, even without the analyser on. Same if you look at the gain reduction meter on the compressor plugin, it's really choppy.
Also, still dazzles me how they never fixed / have noticed the fullscreen bug where the mouse cursor won't change. I mean when you implement the fullscreen button on your program, you would think you test if it works.
Anyway, I'm still VERY happy with this as the most important thing is that I can work again, and all the controls react smooth on mouse input.
