The vram BIOS max setting is 2gb. Is the os able to bypass this limit? Or is it possible to enable zram compression for vram?
The OS does dynamically allocate on iGPUs automatically the VRAM as required
My laptop has an APU 5700U and 20GB of RAM. So if an application or game requires 4GB of VRAM, will it do so automatically?
I may be wrong here, but my understanding about APU is that they don’t use dedicated VRAM like discrete GPU does. I think the integreted GPU of an APU use system RAM. Your RAM is shared between all your devices including the integrated GPU.
I think the 2GB you see in the BIOS only serve to “reserve” this memory for your video card to make sure it will at least get 2GB dedicated for video purpose and nothing esle.
If your integreted GPU need more than 2GB, it should allocate it from none reserved system memory as long as free memory is available.
That is correct

hi, i let Cachy OS RC overtake some older machines with Ryzen Mobile 2000.
R3 with 8Gb of ram shows in Gamemode (i misused hh-edition for laptop;)
“Ram Size 6.68GB”
“Video Driver AMD RADV 24.2.6”
“VRAM Size 2.89 Gb”
greetings
You can increase this value if you add more RAM to your laptop. I noticed this when I changed the RAM from 16G to 32G. Apparently, a certain percentage of the total number of RAM is taken into the BIOS. If I’m not mistaken, in addition, AMD chip and Intel can work with memory. in different ways.
