Using Ubuntu Trusty Tahr (daily build of nov 15) in a core i7-4700HQ and Intel graphics, and dash "fade in" is still slow... and Alt+Tab transitions are slow too... it's a shame for ubuntu to be slow in a new hardware like this...

Change Blur effect to "No blur" or "Static blur" (using Ubuntu Tweak for this) vastly improved performance.

Other solution is include:

export UNITY_LOW_GFX_MODE=1

to the .xprofile file in user folder, like comment #10.

This last solution works well here (and it is very simple to implement!). Why ubuntu not coming with this file configuration active, knowing that 70 or 80% of all desktops, laptops and ultrabooks does not come with an Nvidia or AMD card, just a single Intel graphics? And knowing also that the hardware can do all these effects is not installed by default (like Nvidia and AMD graphics cards)?
