I have a NVIDIA GeForce GTX 1060 graphics card, a Windows 10 operating system, a 7th Gen Intel® Core™ i5-7400 processor. So I am very new to pc gaming and all of that, and have just recently bought a pc about 3 days ago. On pc, I was really looking forward to playing rainbow six siege, since I had played it on Xbox for a while, and I downloaded it on steam. So I get into a game and start messing with my graphics settings ,and I see that I only 128 MB of video memory while Rainbow Six Siege needs around 1.5 GB of dedicated video memory for worth while gameplay. I have tried so much to try and allocate at least 2 GB of my available 8GB Ram memory to dedicated video memory, but nothing has really worked at all. Please, I need help with this.
