I don't have the symptoms Merina is describing, the common issue appears to be:
1. hangs for ~20-30s when switching to portrait select in the character creator
2. character VO (select/attack/choosing which voice etc) seem to be delayed by ~7s from triggering // Some issue with dialogue menu VO but things such as the opening chapter narration are fine, combat and movement noise is fine, menu noises seem fine etc
3. When going into the player character's inventory screen it is noticably slowed, taking 5-10s for the screen to pop up and any action involving the character model changing results in even more stalling/hanging
Internal HDD, steam, no partitions afaik, I'm bad with computers. :'(
