Significant FPS drop after 4.1 patch
I've updated to 4.1 and the editor is basically unusable. The editor became extremely slow and it's impossible to use it, even in the lowest quality preset.
If I switch back to 4.0.2 the editor works just fine. So, it's not my computer.
Can you please verify this?
Your are right, Sorry. We will fix that soon.
The workaround: put this into Consolevariable.ini: r.GraphicsAdapter = -2
Please respond so we know that fixed your issue.

I got the reply from Nick Penwarden. This allowed me to select my Intel HD as D3D11 Device instead of the software: My test level FPS up from 1-3FPS to 70FPS on Low Quality and 20FPS on Epic Quality. Just like the old UE4.0.2 Big thanks.
Add these lines to MyProject\Config\DefaultEngine.ini
Here's the snipped on the log after the changes:
LogD3D11RHI: Found D3D11 adapter 0: Intel(R) HD Graphics Family (Feature Level 11_0)
