Known issues with 4.11?

Are there any known issues with 4.11? My PC was running 4.10 fine with i5, GTX450, 4GB RAM on 1080p. I upgraded to an ASUS ROG G752 laptop - i7, GTX970M, 16GB RAM on 1080p. 4.11 is stuttering horribly in the editor, and while building out the editor occasionally will get stuck at 9% and have to restart.

I’m unable to try 4.11 on my PC to see if it is my laptop or the engine, but does anyone have any information of known issues in 4.11, or perhaps some suggestions as to why this might be happening?

Thanks
