Is VRAM the only important thing when gaming at higher resolutions?

As the title says, does the higher resolution only "eat" from the VRAM or does it reduce overall performance aswell?

It has to compute and push more pixels.

1 HD monitor 1920x1080 = 2,073,600
3 HD monitor 5760x1080 = 6,220,800


The GPU has to calculate every shadow, texture, light, etc 3 times as much with 3 monitor that with 1, so it is a huge drain on the system. If you card can do 90FPS with 1 monitor, figure 30FPS with 3 monitors.

The Vram is being used so hard is because the GPU also stores as much as possible on the Vram so you have it readily available when entering a new area for example in a game.

having a higher resolution tripled those objects size.

So whenever your thinking hey nice and easy peacefull area ingame, your GPU doesnt sit and wait it starts to work on the next area for example.
