Thank you for that info
Sadly that did not work at all.
I do have Win 10, am using SH5 in administrator mode with win7 compatibility and my Geforce GT720
driver was rolled back to 382.05 with no further rollback possible.
I have the correct directX version.
Might have to do a full reinstall and keep my savegames somewhere else or I will check if I can download and install
