Hey you guys,

upgraded my notebook today from 8gb (1 slot) to 16 gb (2 slots). It gave me a significant performance increase. Now I got around 10 - 25 fps more. Game experience is also smoother. I dont go below 30 fps anymore. Before I went even down to the teens. RAM use is 11gb now btw.
System is i5-7300hq and Gtx 1050ti (4gb Vram). I guess that this is not a fix for everyone but here the CPU is clearly the limiting factor. If that is the case with you too then you might wanna consider upgrading your RAM.

Having said that, performance of course still needs improvement. And there are still fps drops of like 20 fps.
