AC4 freezing with i7 4770K and PNY GTX 770 But runs fine on a HP Envy with 660Ti

***UPDATE*** I thought it was solved but the problem reared it's ugly head when I started over in the first island which it didn't before until after getting to havana. :(

Assassin's Creed 4 freezes randomly on my GTX 770 but plays fine on my 660Ti How do I find out what the problem is and how do I fix it?

I've gone through Ubisoft and they gave up pretty quick and gave me a code for the 360 version Season pass. A small consolation since I bought the PC game for the graphics.

Here's what I've tried so far:

1. Fresh Install (OS, Steam, uPlay, AC4 all on the C: drive) 120 GB SSD
2. All Drivers updated and installed.
3. Memtest86 (increased voltage which removed any errors)
4. Lowered all graphics settings to minimal levels to see if it was anything in game graphics settings. Still froze.
5. Tweaked global settings in Nvidia CP to no avail.
6. Clean Boot revealed no change in AC4 behavior. Still froze.

  1. Is the problem only with Black flag?

    It seems to be only with that game yes.
  3. I just unseated the Video Card and RAM and gave it another go. It still froze. My wife noted that it seems to be when I'm mid-air. Jumping/diving. Doesn't really make sense but perhaps this is significant.
  4. Heres what i suggest!
    As you already mentioned that you cleaned, installed and updated your Nvidia drivers.
    Now i would recommend you doing the same again!
    Clean the drivers using Guru driver cleaner,
    Install the custom drivers,
    Now instead of Updating to right now,
    Download this
    http://www.geforce.com/whats-new/articles/nvidia-geforce-331-93-beta-drivers-released
    nvidia released this patch specifically for Assassins creed 4 Black fag
    Though its beta version, but worth a shot
  5. I've been trying to avoid rolling back drivers but I'll try anything at this point.

    This is the only solution i would have at this point

    A beast rig like yours struggling to run just an AC4??
    Seams strange
  7. Oops I clicked best solution on your latest post. :D You're solution seemed to have worked. :D MAN This is insane. Should Nvidia know about this? If they don't then how does this get fixed again? I've been running around Havana now for about 10 minutes and no freezing. Whew. I thought I was going to have to fork out another 500 bucks for a new Video Card. :D You're a life saver man.

    LOL didn't even notice. :D That's some funny stuff right there. :D Uh...I mean...shame on you. o.O :D
  10. Ugh...it's freezing again, but this time it's freezing before leaving the first island. Before it didn't do that. Perhaps upgrading to the next full drivers?

    Sorry, i guess yeah, if an older driver kinda fixed your problems, i guess the newer ones might be,
    But if not, contact NVIDIA
  12. these are the gtx 770 settings and seen some have to disable v-sync http://www.geforce.com/whats-new/guides/assassins-creed-iv-black-flag-graphics-and-performance-guide#assassins-creed-iv-black-flag-optimal-playable-settings seen a lot of issue with this game on the web .

    Yeah I've tried turning everything off and set low. Nothing.

    I've resorted to swapping out my 770 with my 660 Ti temporarily until I finish the game then I'll put my 770 back in so I can play games that are made by companies that appreciate their customers loyalty.
  14. Mr.Wick your problem is rather an unusual one!
    A notorious trojan, or the drivers! Problem resides within
  15. Nvidia support suggested the 350.13 hotfix drivers. The game allowed me to get past the main sequence in Havana but froze after 5 minutes of running around. I guess I'll continue playing on my 660 Ti until they find a fix. It's not a virus for sure since it still did it after a fresh install. Also if it is a virus (if that's what you were suggesting per "trojan") It's not a very effective virus as all it does is freeze AC4 with very specific hardware.
  16. it is mostly a issue with the game do a little searc on web you find how many have issue with it and the gtx770 .

    I'm not sure if you are being condescending or just trying to get post points. Yes, I'm aware others are having issues. I'm trying to eliminate all possible problems on my end. I am speaking with Nvidia Support and have tried one new thing that resulted in no solution. We'll see next week if there is something new. Most people I've noticed don't actually take the time to contact the developers with these things. Ubisoft acted like they'd never heard of the problem. Nvidia support seems to think my issue is unique. You and I both know I'm not the only one with the issue. Perhaps it hasn't gotten fixed because people refuse to use the proper channels and post the solutions to other areas. I'm just trying to do my part. Thanks for your proposed solution of "searc on the web".
  18. not trying to get post point they do not matter for me ,did you try that gtx 770 in another system and see if it freeze .
