Hello,
I really want to get this game but it seems that the official release created many crashes and issues for users.
Most of the post release evaluations are bad so I hope it was fixed in the latest patch 1.0.1 in november.
Can people attest that it is running well now ?
Also, is the controller support manageable ?
Thanks

I haven't had crashes with version .0 or .1. Granted I'm in Linux using Wine, but other than my poor cpu causing me to stutter I've not seen many problems. Thought there seems to be at least one quest that is bugged for me, as the game froze when I completed the tournament quest with a gang leader. Other than that, some streamer got his save corrupted and nothing else.

I got the game since release and I didn't run in any major technical difficulties. The game tends to crash on launch due to mods being in the wrong load order, but that is my fault, not the game's.
When a castle is too crowded during a siege troops like to glitch into the walls. These can usually not be killed and the castle cannot be taken by you. That is nasty but since you can retreat to the campaign screen and immediately attack again, those few remaining troops respawn at default entry points. Then you can attack with your remaining forces and the enemy only has 5 to 12 that gliched into walls the first time, now being on the battlements. So I can deal with that.
I heavily suggest using vortex mod-manager, just launch you game through vortex. People keep complain about the game's default launcher being not that good, but Vortex is nice.

But I think in vanilla the game is nice too.
