So, what exactly is the difference in quality when using a PCmonitor between the ArcadeVGA running at the native resolution and an ordinary card running Direct 3D stretching?
The difference actually depends on what types of games you play. The most striking improvement is with older, classic games which have "graphics ROM" type character sprites such as Galaga, Pacman, Space Invaders and the like. The difference is clear.
Pictorial graphics of later games show an improvement in sharpness with no loss of detail, giving a picture where you can see each individual pixel of the original. On this typeof game it is a matter of taste as to whether you prefer this level of sharpness against a Direct3D picture which slightly blurs and softens the edges.
