I have the severel problems:
i5 6600k on Gigabyte B150-HD3P
16 GB RAM
OS (Win10) on SSD
Game on different SSD
Radeon 5700 XT
First I run the game with my old Nvidia GTX 970 - but it was so low on FPS, so I bought the Radeon RX 5700 XT
Game looks good - but I have the extrem long loading If I talk to a trader or person (about 30 sec). Game crashes from time to time an most of the Cutscene doesn't work.
Set graphic to "very hight" helps with the cutscene. But not with the rest
For test, I installed the old GTX 970 - and there are no black loadings screens - I could immiadly talk to the trader. But game looks shity.
I try to install the game on a HDD - it's getting slower
Disable Uplay Connect - nothing
delete als cloud save games - nothing
Change also the graphic settings - a bit faster if I set it to low (only 20 sec in the black loading screen)
I try the DDU driver uninstall - nothing
Back to an older radeon driver - nothing
Last step will be a bios update - maybe this helps, but I doesn't think so.
Looks for me, like a radeon driver problem.
Because with the old NVIDIA card, it runs
