Not prominent in dos games, but mostly in windows 3.1 games.
But everything can only be emulated, because the graphic drawing is done
in the coprocessor.
Block transfers, Clippings and line drawing can only be emulated.
If not emulated close enough to the original hardware, it is plainly pointless to do so.

2 Questions:
1) How can you tell while in dosbox, and the game is running, what mode is it in?

2) How many games actually would write all card drivers to take full advantage of each card?

Thanks
Jack

I'm not sure what you're asking exactly, but VESA supervga modes work quite well, and people have worked on more specific cards like Glide emulation for early 3d cards.

And Win 3.1 works great, so I'm quite confused unless you have a specific game you mean.
