Right now I have 8GB of ram on my laptop and 2.1GB is used for hardware reserved. And I found out 2GB is used for my AMD Radeon(TM) RX Vega 10 Graphics memory. So that made my ram only 5.94GB usable. I have GTX1660ti, So I want to use as much ram as possible for the best gaming performance. I tried lookup in bios but there are no graphics settings. I tried the registry editor method. Neither worked. Is there any way to fix this problem or decrease dedicated video memory besides upgrading my ram. I want that to be my last option. Thank you.
