Radeon & nVidia GPU's
It hasn't seemed to cause a problem using nVidia GPU on Freesync monitor but the other way around using Radeon GPU on G-Sync monitor it has caused a problem.
Just been setting a system up for future use with both the nVidia & AMD software so it's possible to use either I've found screen flicker or a re-setting of the G-Sync monitor every now and then which is way annoying - Is there an option to un-check for this? - Using Windows 10 64 - If not I'll just not attempt using Radeon on G-Sync monitor - But it's good to know if there is an option I'm not aware of that may fix the issue. - Thanks
