What does VRAM affect?

[jm-april20]

Does it affect how mamy frames I can get?
Does it affect how high I can set the graphics to?

Higher game resolutions require more Vram also higher game settings also require more Vram but the speed of your Vram affects game framerates.
In my humble opinion 4GB of Vram is a must have even for 1080p gaming

Yes and yes.

If there is not enough vram for specific application, you're using, then performance will be significantly impacted.
Amount of available vram is directly responsible for possible graphics quality settings.

As others have said, Yes and Yes. If you run out of VRAM (video card memory) than the video card will have to swap memory from the disk. This isn't very fast and causing massive frame drops. Usually VRAM is directly associated with Texture detail. Turn down those settings if you don't have enough VRAM.

I use to do this on my old video cards playing newer games. Didn't have enough "video memory" so I turned down the texture details and left everything else on ULTRA settings.

Most games are VRAM hungry as they have high texture quality and you will notice that some games such as Rainbow Six Siege warn you when you increase the texture detail in regards to the VRAM
