Well I was working out of town for last 5 months and haven't been following things that closely. I installed the new 381.65 driver on my main boxen as it mentions support for the new Creator's Update for Win 10. I'm not sure if it's just the last few WU's but my PPD seem lower on my GTX970 and GTX750 now. Is there still an issue with newer NV drivers and/or the new core 21 and that hotfix? Not sure what the Creator's support is or if it's even necessary but I'm thinking of reverting back to 373.06
