These tests in themselves are not enough to condemn DPaint as the culprit in
the 'slow load' problem, but here's the kicker: Exit from Dpaint, and use UShow
to load up the same hi-res pic you were using to test DPaint. Click the left
button to 'set' the picture in place, and slide its screen down to expose the
CLI (use 2 if necessary) and PM. Now use UShow to load the same pic. (or
another one to clear the buffers, and back to the same one to retest). Observe
that the second pic loads just as quickly as the first one, even though it is a
similar condition to loading a pic into DPaint with the same screen
configuration.
My conclusion is that the 2090 has been given a bum rap for supposed DMA
interference with 640*400*4 screens, when in fact it is DPaint itself that is
somehow causing the poor performance. As soon as I can borrow ProPage, I will
perform similar tests on that, since that is the other one that people say they
notice the poor performance with.
Let me know how your tests go.
