Don't know if anyone has said this yet, and am too lazy to read 18 pages after food coma, so..
I just beat the main story the other day, and my biggest issue was dialogue freezing on characters. I had to skip scenes, and didn't even get subtitles for most of it, so I missed some big scenes like my romance scene with Cassandra, I had to mash the skip button half-way through and sometimes it just froze. Took three tries to even get through it, and I missed half the dialogue.
Also, when I completed the main story and got to the cut scene after the big bad boss battle, a lot of weird things happened, it didn't freeze but I got to see some weird camera shots, like for a few moments the camera panned between my Inquisitor smirking and then some stairs, and a wall. After wards, when my inquisitor walked inside the throne room, he started talking to somebody without and sound at all, and this somebody didn't appear, nor did I get subtitles for what he was saying. The only reason I figured this out is my Inquisitor eventually had subtitles appears that gave clues to the fact he was talking to somebody else.
And I did try both re-installing the game to my hard drive, and multiple save files. I could get over the other bugs, but the dialogue and especially that end-game cut scene seeming almost unfinished with how buggy it was really irked me. And, I haven't seen anything about a patch for any other platform then PC with my goggle searches.
Loved the game till I hit these cut scene problems, and I'm dreading starting my second play through right now.
