increase the amount of video memory

[niskagy]

you need to increase the amount of video memory from 512 to 2048 MB. you do not need to write that the system automatically takes memory from RAM. she doesn't take anything. this is clear from monitoring and tests. you need to increase it. need a bios with the function of increasing video memory

Integrated video (iGPU) does not have room for keep VRAM, it relies on System. System will work this out and allocate/assign spare/available system RAM to VRAM automatically when required up to max limit. System will also take VRAM back when required (the number is dynamic, not fix). During the good old days, we could do this from BIOS but now OS is smarter.

The following document shows Max shared RAM for Intel iGPU versions

Note: Recently people post Youtube on internet saying they can change using Regedit. Many people try but the results are unpredictable.
