Witcher 3 crashes every few minutes

I just got Witcher 3 and was so excited to play it, but I can't enjoy it. The game crashes every few minutes (around 5 minutes) without a warning. I'm playing it on highest graphics but as it runs smoothly I guess the graphics aren't the issue. One time it crashed when a cutscene came up, another time in the middle of a fight.

My OS is Windows 8.1, I hope you can help me to get the game running

EDIT: Downvotes, telling me the reason would be helpful, thanks

Solution 1:

With the newest NVIDIA drivers 353.06 WHQL, I can finally run 'The Witcher 3' without crashes every 5 minutes!

I'm not sure, if switching off V-Sync and playing in full screen (native monitor resolution) mode was necessary too.

Solution 2:

There are some reports that changing the framerate limit can help with certain types of crashed in this game. The most common solution I've heard about is to set the fps limit to unlimited, and either play that way or use an external program to limit the framerate.

There are some issues here, both with the game and with the newest Nvidia driver, which also tends to occasionally crash for me. I've a GTX 970 as well, and while it is far from unplayable, I also get reasonably frequent crashed. It is worse for me with the latest 1.05 patch. Downgrading is likely problematic as from what I've read the save games are not necessarily compatible with earlier game versions.
