If you do not have a dedicated graphics card on your computer with its VRAM memory, it is normal for the program to allocate a portion of RAM to the graphics, since it is required to operate. However, if you have a graph dedicated to its memory, why does Windows continue to be part of the computer's RAM?
RAM memory is shared by graphics
To see what we're telling you, you have to open Windows Task Manager, access the "Performance" tab and select the GPU on the left.
If you look at the area below, where the graphics card information appears, "Dedicated GPU memory", that is, effectively and take this example, VRAM graphics card, 8 GB. But just below appears «Shared GPU memory«, Where it turns out that 300 MB of 16 GB is allocated, and is actually to the left is the term« GPU memory », where you can see that 4 of 24 GB are used, just 8 GB of graphics card added to the additional 16 GB shared by Windows.
This means that Windows uses a portion of the computer's RAM to assign it to a graphics object card, but why is this done?
Shared memory is a virtual reality
To start with we'll tell you to worry, it's not that Windows "steals" RAM at all (actually, yes, but it's a bit less). The fact is that this shared memory for images is used by Windows with the GPU processor because we don't have graphics disabled in the BIOS (so if you want this to stop it you should have go to BIOS and disable iGPU, even though we do not recommend it to happen).
In any case, disabling the GPU is not something we recommend because if the supplied graphics fail at any time, we will be defenseless because we cannot use the compiler yet and will need another dedicated graphics.
If you want to do it anyway, you have to install the BIOS and go to the Advanced Settings section. From here it is up to the motherboard maker, but generally we will have to go into the chipset setting where we will find something related to "Internal Graphics", where we can disable.
This little bit of RAM that "Windows" steals "from us is actually a few MB, not 16 GB" shared "because it's not allocated as such, it is simply available but not used to share the graph in case it was needed. in BIOS we chose iGPU as the main animation but found the dedicated one connected, Windows will use VRAM provided graphics for the GPU.
