Hello,
I've had the same problem but my symptoms were very different. Upon installing my new ASUS STRIX GTX 1080, AI SUITE III crashed and wouldn't work (I forget if it gave some kind of error). I then uninstalled and reinstalled it and everything seemed to work fine. I then tried playing games and there were serious problems. In Dark Souls 3, for example, simply moving the mouse caused serious fps drops down to the 20's and even lower. With Overwatch, there would be microstutters. Lowering the mouse polling from 1000 to 125 relieved most of the issues but some fps problems were still apparent, and I knew that those should not be happening with an i7-6700K and a 1080. The CPU usage was also way higher than it should be. Overwatch was using about 40% but the total CPU usage would be as high as 80-100% without any apparent program causing this, which most likely caused the microstutters. Even having the CPU on idle used 10-20%.
After trying so many different things to fix the problem, I decided to do a Windows reset (the one that allows you to keep your files) and after reinstalling some programs, I saw that all problems were gone. I could play Dark Souls and Overwatch with 1000Hz polling for my mouse and the CPU usage was normal. I wanted a program to control my fans so I reinstalled AI SUITE III and all the problems returned. Even uninstalling AI SUITE did not relieve the problems. After a second Windows reset and not reinstalling AI SUITE, everything works correctly.
Because of all the time I wasted trying to figure out the problem, I won't be reinstalling AI SUITE III again. If anyone has similar problems to mine, know that AI SUITE III is currently the cause.
1. Z170-A BIOS Ver. 1602
2. Windows 10 Education x64
3. Most recent but version not known. Will not be reinstalling
4. 368.81 and 368.95 (which addresses a DCP latency bug)
Thank you,
David
