Lol. But thats the problem. Now that u have proof (that something is going on), its feeds the ocd... ;-) Not playing any of the games mentioned anyway, and since all previous probs i had with drivers/GFE are gone with 355.80 anyway....

My install on one of my laptops seemed to hang on "installing PhysX software" portion, but after killing it through Task Manager it seems to have installed everything and says it's using the new driver. Windows 10 and 980m of what it's worth.

What's with all these driver issues lately? Before I always updated but I haven't done for a long time now.

Nvidia's drivers under Windows 10 are just bad. I don't really get why either, they were pretty pro-active about getting drivers on the insider builds. People reported all kinds of issues and they were just never resolved (the SLI memory issue was apparent for nearly 6 months and it didn't get fixed until like 2 months after release).

I'm still on 8.1, and wonder of the issues persist there as well?

No idea. Honestly it's hard to gauge what issues that people are having that are caused by the driver itself, a configuration issue, or just user error, let alone across multiple OS's. All I know is that W10 seems to be an issue for Nvidia.
