Minor update + Win binary:
https://github.com/tsiv/ccminer-cryptonight/releasesNo longer wasting CPU cycles on busy waiting, some checks on the initial memory allocations before getting to work and per device launch settings.
Seems like we have a lot of Win 8 users with problems, but apparently it works for some.
I have no problems with windows 8.1, just the performance on 780ti is pretty bad compared to 750ti cards. i.e. I'm getting similar hashrates to what others have reported here for the 780ti ~270hash/s (using 4x120).
