I’ve tried to reproduce this on my end, but I’m not seeing anything really. This could be I’m just using template projects that haven’t really been setup in any specific way, but you did mention this is multiple projects.
Looking at your DxDiag, your AMD GPU drivers are a couple of months old. Have you tried updating to the latest ones 15.30.1025.1001 that are available here: http://support.amd.com/en-us/download
This could be a likely cause, but at the moment I can’t say for certain since I’m running on a Nvidia GTX-680.
If you’re able to reproduce this in a simple test project I can do some comparisons in our Lab with multiple machine setups and on my machine to see if I’m seeing the same results.
If this is only happening in your personal projects, it may be worth doing some CPU/GPU profilling to see where the hiccups are happening when you’re turning/moving the camera, but I’m not sure if this would help much since it’s only happening in the editor and not when you are doing Standalone or recording with OBS as you mention.
