Just wanted to share about UMA_Game_Optimized because I had no clue this setting existed and happen to stumble across it today. Not sure if its adaptative to how much ram you have but after enabling it the gpu is now showing 4gb of ram.

Have you actually measured any performance difference?
According to my understanding, there should be no performance difference at all (hardware should not care). If there is, it would be caused by games & applications treating the iGPU wrongly, as if it was a dGPU and hence using that value in wrong ways that improve or worsen the performance.
No it’s on my to-do list now but I would imagine having pre allocated the ram for the GPU would reduce memory management overhead.
It’s anecdotal but (on Linux at least) Steam in 4K locks up and the driver appears to crash with Auto but does just fine with the reserved 4GB.
