Noob question, but I was looking at HWiNFO to see how much VRAM I have, then I began to question it, What exactly is the difference in the Virtual memory and the Physical memory, and how does it affect my gaming? By my knowledge, and I'm not that great when it comes to dealing with GPU's, games use VRAM, but how does the Phyiscal memory get used up? Also when it comes to setting a game's VRAM setting, which one would I use? the virtual or the physical?
