Had the same issue as well. It got so bad that every 2-3 games I experienced a crash. So, I issued a ticket to support (they were very helpful and quick to respond btw) and they advised me to uninstall mods (don't have any), update the drivers (done that previously), delete all files from the cache folder etc. I've done it all and it did help a bit but the crashes still continued. What solved the issue for me was that I reduced the graphics to medium overall. Since then I haven't got a single crash. Usually my PC is more than capable to run the game even at maximum graphics which makes the problem strange but at least now I can play uninterrupted. My advice is to try a few games with lower graphic setting and see if it works. Hope this helps!
Edit: I still get some weird FPS drops sometimes though
