how important is cuda for ccminer v2.2.2 (or generaly ccminer)
I installed regular nvidia driver (think it is 385..), and used v2.2

But version v2.2.1 have cuda9, and v2.2.2 have version for cuda 7.5 and cuda 9..
So i installed cuda 9 and drivers are fu*ked up.. Monitor can't work and TW is only solution to see what is going on.
Once I enter TW I see large files (like no drivers installed)

So I need to reinstall Windows 10 again, but wondering, should i install cuda 9, cuda 7.5, or just latest nvidia drivers?
IS there bust in preformance with cuda drivers ?

Since I got error with Visual Studio, when installing cuda 9.
