AMD Vega 56/64 mouse lag

[chryleo]

you guys wont believe this i just replace the display port cable and that did it! thank you so much!!!!

I have the same lagging problem with a vega 56 and HDMI cable.
May I have more detailed information on your cable? e.g., DP 1.2 or 1.4? or HDMI 2.0?
Thanks a lot!!!

I used to encounter the mouse shutter as well.
One day I noticed my Vega was running at x8 instead of x16. Turned out it was sharing bandwidth with slot 4.
I freed up the slot and now the issue is gone.
Hope it helps.
