Please post your Nvidia driver version, NVCPL settings and how it is functioning. I typically tend to use the latest Nvidia driver but had 399.07 installed at ACC release. It ran really smooth but since I'd never really experienced driver issues before, decided to go with 399.24. It proved to be less than optimal with a 'clean' install and the exact settings...(both in game and in NVCPL). If you experience micro-stutter in ACC, you may want to experiment with a few different drivers. I reverted to 399.07 and the issue was resolved. The most important settings in NVCPL for micro-stutter reduction seems to be power management. Set it to 'prefer maximum power'.
