New Monitor Stuttering/Freezing - (MSI Optix G27C2)

I bought this monitor and I'm having an issue when connected via displayport. Everything works fine when I connect with HDMI @ 120hz however as soon as I connect it using displayport the screen will start freezing every second. The mouse will be completely frozen on the desktop for around a second and then jump across the screen when it becomes unfrozen. Does this sound like a faulty cable? I'm using the displayport cable that was provided with the monitor.

I'm on windows 10

GPU is MSI Armor RX 480 8gb

I've done a clean install of my AMD drivers and have the latest software version.

Any help is appreciated
 
I just got the same monitor today. Also running RX 480. I'm going crazy about that stutter. I know the driver are the cause, as soon as you uninstall the drivers everything seem to work fine, and if you reinstall the latest drivers, same problem.
 
I've been having a similar problem only my mouse being idle is what kicks the stutter up. Any video I watch (YT, Netflix, from my files) and leaving the mouse still for 30+ seconds and it starts skipping but audio is fine. This entire system was fine until I got this MSI Optix MAG27CQ monitor and this is the first time I've used DisplayPort. Is the guru3d solution a good bet or am I having some other issue?

I've also noticed in task manager when this happens, my GPU-3D process kicks WAY up so something around there is causing this.

edit: I went to try the guru3d option but the installer claimed no AMD hardware was found which is silly cause I have the current 18.x.x installed.

edit 2: I switched back to HDMI, sacrificing that 144Hz for 120 but it seems to have stopped. Nvidia still says my monitor/cable is equipped for HDCP support but no more lag on idle mouse. Maybe its the cable? Or just the integration of the software/HDCP ill compatibility?
 


That isn't a solution for me; I don't have a setting on the monitor to turn off HDCP, my GPU is Nvidia which doesn't allow to turn that off and the Raedon software on my board doesn't have a software interface to turn it off.
