Hi guys, just thought I'd give you my views on Unity post patch, although before that it's important you understand my experience before v 1.3.
I have been relatively lucky as my game, at least performance-wise has run okay. Don't get me wrong, I've still had loads of bugs, FR drops, big stutters in certain sections, pop-in and npcs changing gender and clothes before my eyes, but it's never been game-breaking, just annoying. My bigger concerns were actually with the actual gameplay and just how unresponsive and at times broken it was.
With the patch installed I've noticed many differences almost all for the better.
Performance-wise, I've experienced less bugs, less FR-drops - although it still tanks a little in some locations like the interior of Notre Dame - and no stuttering yet. Still a lot of pop-in, but nothing worse than many other open-world games, and I've yet to see anyone change genders or swap outfits as I approach. However the detail of the clothes does still draw-in quite noticeably.
The biggest difference I have experienced though is in the overall gameplay: everything is much more responsive.
Most notably the parkour and general movement has gone from being a sticky, unresponsive, unpredictable mess where Arno did what I wanted about 20% of the time to now flowing more to the point where it's actually flipped to around an 80% success rate and is enjoyable. I'd equate it to Black Flag levels.
Stealth has improved drastically as well, as the broken cover system now actually functions. Not all the time, and there are still parts of the environment where Arno will refuse to stick to, but there seems to be significantly less of these moments and it's much more responsive. Pressing 'A' now consistently works.
Combat is the least improved but is still more responsive to your inputs than before. There is definitely a tiny bit less lag on parrying and a bit more of an improvement on on how quickly Arno will roll, attack and switch out of a combat stance and run away which is useful when trying to avoid bombs.
All-in-all I have to say i'm very impressed with the improvements, and they seem significant enough that they were in no way something Ubi knocked up in a couple of weeks as a response to the outrage - this patch seems to transform the game into what feels to me like what the devs intended the final release to be. I.e. what we got at release was the beta form of the game but rather than wait, the suits decided the game had to be shipped to meet the holiday season date.
