CSM not working on 2017/2018 public beta

I finally found some time to check out the public beta! While the godrays (in- and outdoor) and the lensflare seems to be working just fine, the CSM doesn’t work for me. I tried diffrent settings in the Advanced videos options, but it didn’t do anything. I am guessing it is graphics card related, as I have an AMD card and the same issue came up, when CSM was first introduced in 2016. It could be solved back then by setting “-force_vendor_id 0x10DE -force_device_id 0x1180 -dxlevel 95” in the launch options, but this doesn’t seem to work this time around. Anyway here are some pics and my specs. Hope there will be a solution for it, as the game looks awesome in the pics!

DELL Inspiron 15r se
Intel Core i5-3210M CPU@ 2.50Ghz
