Custom Resolution Utility (CRU)

Also in the nvidia control panel, it lists the 90hz for one of the monitors under the normal PC resolutions, but for the other 2 it only lists 90hz a separate "custom" section resolution. If I go back in to the one which is listed under the PC resolutions section, edit it again, even without changing anything, it then moves it to the "custom" section, but the same problem exists....it switches to 98Hz when it goes to a full screen game.

Where is 98 Hz coming from? Is 98 Hz one of the default refresh rates listed in the Windows display settings or NVIDIA control panel or did you add it? Where are you seeing the refresh rate reported as 98 Hz?

It will be listed under PC resolutions, but where it's listed in the NVIDIA control panel shouldn't matter. CRU changes stay in effect until removed. Also NVIDIA's driver currently has a bug that causes it to ignore all changes with DSC monitors, so I don't know if CRU will have any effect. You will have to try it and see what happens.

That depends on why it's happening. If it's a signal quality problem, a better cable might help. If it's some sort of bandwidth issue, reducing the refresh rate, color depth, or color format might help. If the monitor is not handling fluctuations correctly, increasing the minimum FreeSync range and reducing the refresh rate or capping the frame rate below the refresh rate might help. Normally though you shouldn't have to do any workarounds, so if it's not a signal quality issue, then it might be a design flaw in the monitor or an incompatibility with the way NVIDIA handles variable refresh rates.
