After doing a bunch of testing, I've concluded that the issue is indeed a driver related one. In the previous thread (you can find a video displaying the behaviour on the previous thread) I tested a bunch of things that could be causing the issue and found out that my second screen was the culprit. The work around was to not display animations on the second screen or to disconnect it. Now after further testing I've found that that if I enable eyefinity, the DPC latency spike also doesnt happen, which leads me to believe that the issue is mainly caused by GPU acceleration. On Nvidias side there is an option that can be enabled to allow for GPU acceleration on multiple screens, but as far as I know no such thing exists for AMD. I've been in contact with AMD support and hopefully they can provide a fix to this issue.

I've been having the same problem for months. Made few threads about it and many people posted they are facing the same or somewhat similar issues aswell." class="reddit-press-subreddit-link" target="_blank" rel="noopener">
