Hello, Wine has 2 DDraw drivers: An accellerated HAL driver and a software-based user driver. I've noticed that the HAL driver uses many basic functionality from the user + gdi driver, and that the hal driver is the prefered one. But is there any situation where the user driver is used directly?
Thanks, Stefan

From what I know, both are almost exactly the same code-wise. The only
difference being that the HAL one could support DGA / DGA2 whereas the User one not.
After, I think that this is here to be compatible with Windows that always exports these two 'basic' drivers whatever your installation (would have to check this point on my Windows laptop though).
