If you have dropped frames during playback (not at the start of the movie) there is something wrong with the acceleration maybe driver or something is not working as it should. If i play a movie no matter which codec even HEVC i have a CPU usage of about 20% and no dropped frames and my CPU is an old AMD Phenom X6.
As i switched from Kodi 16 to Kodi 17 i have had some issues with HEVC and 4k. I could only solve this by using Windows 10. I guess the drivers of my GPU (GTX 950) wasn't well supported in Win 7, maybe missing api functions.
After i have switched to Win 10 64bit all issues was solved. I use this setup more than 12 months now. I have never updated my GPU drivers or Win 10 because it's working.
If you disable 'Sync playback to display' Kodi shouldn't touch the playback speed and the frames. If you have dropped frames now there is definitely something wrong with your HW or drivers. Maybe an incompatibility netween your devices. Very hard to tell.
If your HW is capable only enable WASAPI and passthrough and all should be fine. I guess i remember something was wrong with Kodi 16 and Atmos because of the metada not passing through but i can be wrong.
It's hard to get you an advice because of so much possibilities with the HW, OS, drivers and so on.
I have build some HTPC for my buddies and all i can tell is i always use Win10 64bit, an NVIDIA GPU (often GTX 950) some cheap mainboards and CPU and Kodi 17. I never experienced such issues like audio drops or stuttering or bad movement in the picture/audio.
