I don't know if everyone is playing this with a wireless controller, but I've found that the cause for my massive stuttering, even after patch, was playing with the controller in wireless mode. After I plugged it in with a cable it never stuttered again. Hope this helps someone

Same here, on PC, started happening ever since the Yule Festival began. It's pretty annoying.

I've been playing Valhalla since launch, and got the Moonlight axe since launch. I played through the entire game with it and after about a month of not playing the game I come back and there's no fully upgraded Moonlight axe to be seen!! It just vanished and now I have a moonlight axe on my inventory with no upgrades!! Where did the fully upgraded axe go?!

Yeah, happens exactly the same to me. But I've noticed that if I've had the computer running for a long period of time, I'll start the game already stuttering, and if I restart the PC I can start the game buttery smooth, but like half hour after the stuttering starts and it only gets worse and worse, not even a restart of the game fixes it for me at that point. There also seems to be a server-side issue cause the game borks everytime I take a photo using photo mode. The game literally freezes for a few seconds when coming out of it. This is really frustrating... Ubisoft really needs to invest in their QA team/process cause this is unacceptable for a game they charge up to 130€. These kind of issues shouldn't happen. I love Assassin's Creed, but this is getting really annoying by now.

@ceebezee Same here, I have 6 hours of game and it's getting worse. At one point I did the W10 October update and it got better, but now it just makes the game unplayable. Everything lags, gameplay, sound, menus...EVERYTHING! 100€ for this mess...

For the few hours I've played I've come across a few bugs, but these have been the most troublesome.

Everytime I switch input from mouse to controller and vice versa, the game freezes and loses sound for a few seconds up to a minute.
Frequently the game dips the frames by a lot, during gameplay and cutcsenes, also affecting the sound, making it very laggy and ruining the experience completely. This problem was worse, but got better after I updated W10 to the October update, but still happens, just less frequently as before, but still very annoying.

When I use photo mode, when I upload the photo sometimes it gets stuck saving it, and when I press to go back, it freezes the game and sound for a few seconds.

I'm running the game on high with an i7-6700K, GTX 1070 8GB VRAM and 16GB RAM at 1080p.
