It depends on the resolution of the monitor. In terms of pure area it's about 45% larger.

Wow...
Just shows how bad I am at math! Lol!

2560x1600 > 4million pixels, dot pitch is small too which doesn't help performance

1920x1080 is 2 million pixels or more if x1200.

Visually theres only a small benefit but pixel wise it's double.

Every other sim locked at 60Fps on 2560, but Clod is truly next gen, I pity the triple screen simmers who have 3x30" or even 3x24"
