Okay, playtesting and whatnot done. Since we've been asked to put concerns here, here they are.
Here's my experience with the patch:
1. If you have an AMD vidcard, do update to their latest driver (4.12) which was released 2 days ago. Made things much smoother (actually, in my case, the FR went from absolutely unplayable--although it was fine, pre-patch with the .11 driver--to smooth, so vidcard drivers are a factor here). I also ran a "repair" on the game files itself. Having said that, the front screen, which was working perfectly before (you know, the one of the line of mages & Templars heading to the Temple), apart from it freezing with the Origin surge, now stutters regularly, then I get a laugh as they all race to catch up, stutter, stutter, freeze, RUN GUYS WE'RE LATE... stutter. The FPS within the game was much better, in my case, however it took a bit of fiddling to get it there. Someone with less computer experience (I'm as effing stubborn persistent as Cassandra Cullen) would have given up.
2. The workaround that is listed on the front page of the patch thread is a must. Fixed the shiny and textures completely (I run mesh and textures on ultra--other things on low/medium. Tested on high, still looks good. I figured since we'd been forced into ultra shaders thus far, my lappy could cope so that's what I use now. In any case, changing this doesn't affect the performance issues listed below--either way). Actually looks really good once that's in--looking forward to the hotfix.
3. Major cutscenes still hitch and stutter (again, like they're being FPS strangled--I have had to remove the FPS fix but putting it back didn't change anything)--but the in synch issue (especially with the pre-Skyhold song scene) is gone for me. 'Twas nice to see Cullen actually sing when he... sang...
The hitch & stutter is not extreme, but it is very noticeable--and is not affected by graphics settings.
4. The "conversation" wheel fix has unfortunately broken a function--if you leave the conversation, now, and want to go back (say, if the ingame dialogue camera places you in a tree branch or something or you're looking at the back of Roderick's head and you want to move your char so you're facing him... or, y'know... Cullen.. or I dunno, someone) you lose the dialogue bubble over whoever you're talking to and cannot re-enter conversation as before. I am also getting a blank wheel when this happens (and I'm testing on conversations I've had a few times so i know what should be there). This is dealt with by hitting esc, then back. Was actually working for me fine, pre-patch.
5. Origin client still crashes game. Must run with overlay off, offline for best results.
6. Load times have (on average) doubled, especially when entering the game. I love the load music, at least. I get to hear the whole theme. Before I made it, maybe, to the second stanza.
So, all in all, performance has, in this case, been improved a bit in one direction while being stymied in the other--however, I will give it an overall "slightly better if you have the know-how and can fix the patch's foibles", which kind of should not really be the case? Not everyone's been playing CRPGs since Dos was a lass.
