the main issue is Larian has not tested their game and yes each patch breaks more games than it repairs... they are out of sync and its getting worse so the number of players that slug through act 3 to an endings are less each patch
The first part was already brilliantly answered by @fylimar, so about part two, do you care to provide any data to back up this thesis?
I am almost finished to upload the complete solo feedback video series. And that includes patch 2 patch 3 and patch 4. Mybe tomorrow all will be uploaded. Then you can chek as a living proof of a downgraded quality with each patch. Because oooooo BOY I was suffering after patch 3 and 4. I almost gived up around elder brain the amount of stutter textures not loading even with high tier pc . At some pont I reduced the graphics but even that doesn't helped.
