Yeah i did, but when i booted the game it said it wouldn't run on that driver version so i updated it, but the game would still crash.
Someone on reddit suggested i rollback my driver to around the time of Veilguard's launch period and so i did that, the game stopped crashing, but instead, after about 5-10 minutes of playtime would stutter at an unplayable rate. I saw some online suggestions for settings changes so i followed that, i set my game to play in windowed mode and capped my fps at 30 and the game seems to be working now.
i had a 20 minute play session before it crashed but then I had a 45 minute play session this morning before work without issue, so here's to hoping i can get to the end of the game like this.
Thank you for your help. the DDU uninstaller info was invaluable.
