Is anyone familiar with the BIOS setting 4G encoding enabled. I am using a Gigabyte Z230 motherboard with a RTX3060 12 Gig video card. With the setting enabled flights in VR seem to be smoother. It may be a placebo effect. Has anyone tested this settings? I think it has something to do with the GPU memory

Slightly outdated info… it is required to be enabled if you wish to use either SAM (from AMD) or ReBAR (from Nvidia), so if you have a recent GPU and compatible CPU then you will want to enable it - some games benefit significantly whilst others don’t much, or even suffer mild regression. Not an issue however as once enabled in the BIOS (along with resizable BAR) it also requires per-game activation at a driver level so isn’t defaulting on for all games, only those where they know it to be a benefit. Worth pointing out that most 3000 series cards sold up to this date also require a VBIOS update to enable support, I believe it came out in April.
Currently I don’t believe MSFS itself benefits much from SAM and it’s not yet enabled in Nvidia’s whitelist for their ReBAR, but you can technically force it using Nvidia inspector… I haven’t tried myself so don’t know if there is any performance change in doing so. Certainly the OP shouldn’t be seeing any change in perf unless they have also done what is required to turn on ReBAR in game so it’s likely placebo.
Would definitely be worth revisiting once the game moves to DX12 to see if any performance can be gained with either enabled.
