Hey Faz8, i was just reading through your post, i have similar issue, but at higher framerate, while playing rocket league (haven't tested any other games), with good hardware and nobody helped me find a solution to this problem on this forum, so i started trying many different recording softwares, i had stutters in all of them, some had bigger/less stutters than others, shadowplay also, until I tried recording my gameplay with bandicam and i get 0 stutters. Bad thing is, that u can only record 10 min at a time with free version and u have watermark on the top of the video. I'm still looking through obs threads to see, if anyone has similar issues as i have, because nobody helped me find solution and idk if anyone will help you either. I even thought about upgrading my pc parts, but idk if it will help with this issue, looking that u have the latest hardware and still have stutters. I'm thinking of purchasing lifetime bandicam license, so i can have unlimited minutes of recording time and watermark removed, but still, it doesn't have same features as obs, which i need, like recording some overlays in the background + recording gameplay at the same time. Maybe try to record with bandicam to see, if u still get stutters. I think issue is in OBS, but idk what is the issue and how to fix it.
