Its actually an i865 and "must remain" an i865. Its amazing, the 3D performance (with shadows and all) is pretty fast if I disable the code that results in the screen blits.
It looks like it may actually be running them through some "Stretch Blit" function. I don't know if this might translate down to a D3D call or not that does a size transform at the time of Blit.
If you'd like, I'd be willing to help out if I can on getting this working better. Sounds like you've gotten a head start on it.

Hi. I've been dealing with a program that seems to be very slow at Blitting images onto a D3D surface. Unfortunately, this is not my code so I can't fix it. Would the above mentioned BltFast/CopyRect patches deal with code that attempts to provide this feature?
Is it ddraw or d3d8/d3d9? Do you have an radeon card? glDrawPixels is pretty slow on that cards. BltFast won't fix that, it needs a better UnlockRect implementation in WineD3D. I tried to do that, but I failed because of a lack of gl knowledge, but I'll make another attempt sooner or later?
