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?
Works perfect ! thanks
I noticed a significant slowdown as well, on my Mac here, although I did not try 4.1 in Windows, there is a difference between 4.1 and 4.0.2.
Same, task manager (windows) shows a not responding every now and then, whenever 4.1 is asked to do somethhing.
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 same problem in my Surface 2 Pro. It seems that UE4.1 had the tendency to not select anything that’s “Intel…” graphic adapter. This is ok in many cases, but it backfire on my little machine where the selection is a software renderer instead. I’m still looking for ways to switch it back to use my intel HD graphics. If any of you guys found out, please update. Thanks in advance.
Works perfectly! Thanks!
I still having the same trouble after doing this =( another fix ? (Do i have to put r.GraphicsAdapter = -2 at the last line of the .ini file ?)
The file should be at:
C:\Program Files\Unreal Engine\4.1\Engine\Config\ConsoleVariables.ini
You should place the line in a new blank line after the last line in the file. Some thing like this:
;r.ShaderDevelopmentMode=1 r.GraphicsAdapter = -2
Be sure to restart the editor.
Works really really perfect thanks!
I got the reply from .
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
[SystemSettings]
r.GraphicAdapter=-2
Here’s the snipped on the log after the changes:
