Witcher 3 crashes every few minutes

I can't find anyone else with this specific problem, but the general "modern warfare 3 black screen" issues people are encountering seem to be fixed by:

• Updating your graphics drivers. I think there was a special release for the BF3 beta recently that caused issues with MW3 at launch. Even if you've updated recently, check for a newer revision.
• Verify your Steam cache
• Disable the Steam overlay

Beyond that I'm afraid I don't know - there's so many tiny things that can go terribly wrong with a recent game and an individual PC setup that I'm not sure how to advise you in your current situation.

I note that you're overclocking, if you stop, does that help any? That's the first thing I try if I'm having an issue of any type while overclocking.

I have this same issue now, to where I can not play almost at all unless I am in a dungon. If I load into a city, fast travel, or have a dragon spawn, it freezes in the same way you describe. I have to turn off my PS3 all the way and when it comes back on it says that my hard disk may be corrupt and does a 15-minute check.

I have over 100 hours play time and this issue has me really down, but here is what I have found suggested around the net:

1. Wait 30 in-game days so that all the dungeons and dead bodies everywhere will ether re-spawn or de-spawn from the game world, which is said to lower the size of the save file. (I can't use this one because if I wait I freeze right after.)

2. Turn off auto save and any other type of save that you have not done your self. (I know it's a life saver, but just make yourself save every 15 minutes or before you think you're about to have a big battle.)

3. Check all of your saves from the PS3 save utility for any saves that say "corrupt" on them and remove them. Also, remove all the really old saves.

4. Hope that there will be a patch for this soon. :)

Let me know if this works for you, and good luck!
