Pixels per second really isn't a thing, unless discussed in terms of compression i.e codecs and such, which wouldn't matter anyways. What I think you are trying to get at is frames per second (fps). But still that shouldn't be an issue in a sim. As an example US television is usually shown in 24 frames per second (fps), however the human eye doesn't start to notice flicker until around 12 fps.

Anyways, does anyone actually expect you to land a sim well? I sure never have been able to....
