Unreal Engine 4.1 Update Preview

Okay, the preview version doesn’t work at all for me. I read about performance boosts so I tried it out, but …

It’s exceptionally slower than the 4.0.2 version. It takes about 1-2 seconds for the project select screen to react to my mouse movement. When loading the blueprint examples project in 4.0.2 I get around 8-10 fps (all settings to Epic obviously) in 4.1 it shows a fantastic 0.00 fps. It takes 30 seconds for a menu to respond to my mouse movement, interacting with the viewport is impossible.

Something obviously went wrong , what’s the problem?
