Sanford,
I wouldn't expect it to be "jerky" on a modern computer. The VOGONS thread I linked to was from 2006, almost 7 years ago.
How it looks is another matter. But unless you saw Ripper played with the VESA-disabled option side by side with the VESA-enabled option, I'm not sure you could tell a difference. And a tiny improvement in the graphics might not be worth the bother of getting a VESA driver working anyway. If it looks good to you, that's what matters most.
