I was intending to run another series of benchmarks with Unreal Tournament 2004 but am yet to find time for that.
Pictures: Old & new
The new one is as much crap as the old one. The size of the window is hard-coded so it doesn't remember its size after it's closed. Nor can it be forced to be of different size from KWin settings. The preview pane is still on the right side of the window wasting lots of space. Also notice the poor layout of the widgets, absolutely horrible.
That is the development they manage to do and - it - just - makes - me - cry.
