My editor FPS rate has dropped after the 4.1 patch
If you are experiencing a frame-rate drop since the 4.1 patch was deployed.
Please refer to this post as the official Epic response to this issue. We will keep this top post updated with the current information and potential solutions regarding this issue.

Thank you for your patience while we work to address this issue. As new solutions become available we will update this post.
The fix will be in a future version of the launcher, but for now, you can edit Consolevariable.ini to change the console settings that may be the cause of the issue.
r.GraphicsAdapter = -2
If the first solution does not help, please download and follow the QFE instructions from here:
Please let us know if this does not solve your framerate drop. Thank you!

Please put this into Consolevariable.ini (best is in the last line, don't add any characters before the line):
r.GraphicsAdapter = -2
You can verify the setting was applied in the console typing in "r.GraphicsAdapter" to get the current value. If you don't see it set to -2 there might be a typo. Please let us know if this does not solve your framerate drop. Thank you!

I got this solution from Nick Penwarden. This apply where you only have Intel HD graphics adapter but UE4.1 select Software renderer instead. 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 to him.
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) LogD3D11RHI: Adapter has 0MB of dedicated video memory, 0MB of dedicated system memory, and 1792MB of shared system memory
LogD3D11RHI: Found D3D11 adapter 1: Microsoft Basic Render Driver (Feature Level 11_0) LogD3D11RHI: Adapter has 0MB of dedicated video memory, 0MB of dedicated system memory, and 256MB of shared system memory
LogD3D11RHI: Chosen D3D11 Adapter Id = 0

Not work for me.
if try play/load effects or element i must force close after ten minuts with CPU 100% and another 10 minuts for try kill UE4 process.
effect play fine with 4.0*
EDIT: that looping script its from UE? Script: chrome://browser/content/preferences/applications.js:1192
not the first time a popup jump because a script its eating my resources since update. ¿perhaps some bug in a script are looping a eating resources?
Big drop of FPS for me. GTX 670, i7, 16 GB Memory (running inside viewport).
Here's the reflection scene in 4.0.1:
Same scene running in 4.1.0:

Intel i7-2600 CPU @ 3.40 GHz 12 GB RAM dual monitors NVIDIA GeForce GT 545
Effects Cave frame rate ~ 24 fps
I noticed in the log that the engine is indeed selecting the correct graphics driver.
NOTE: We only used 4.1
I have a laptop with dual GPU, one Intel 4000 with 1 Gb, one Geforce GTX 660 M with 2 Gb. My FPS was between 4 and 6.
I made the change in Consolevariables.ini and Defaultengine.ini
Then I just realize the Geforce GPU will work only in Fullscreen mode, I setup the editor for fullscreen, But it didn't works at the first run, then I closed and opened again, It begin to works but crashed several times, then I went to Nvidia site and I got the latest drivers for my GPU, run again and....
Now i have 20-25 FPS (medium)... some demo i have 30-32 and other i have 18-20, but it is enough to work and enjoy this powerful engine.
I think EPIC / Unreal team must to be more clear about this kind of subjects... I used 3 hours to resolve this technical issue. I was pretty close to cancel my subscription. Just something like this:
Laptop users with dual GPU:
If I had this 2 simple lines i was able to solve this issue in 2 mins and saved a lot of time.
Please , I'm Having a problem with UE4 v4.8.3 and its that its using the Intel HD 4400 GPU instead of the ATI Radeon 8670m .. i tried installing the latest drivers and setting the UE4 editor to high performance in the switchable graphics and everything ... and even installed windows 7 but nothing changed..
i'm attaching the LOG of my project along with the DXDiag information file
