--- Comment #10 from Roderick Colenbrander thunderbird2k@gmail.com 2010-05-27 12:03:20 --- While perhaps we could add a dummy videoprt.sys but likely it won't help much. The direcpll dll is responsible for retrieving gpu information like gpu clocks, amount of video memory and other information. In order to obtain this information it uses a kernel module roughly to access GPU registers through memory mapped I/O. For a part it uses the entech.sys module for this and videoprt.sys appears to be some generic interface which can at least poke with some legacy vga / vesa registers, interrupts and other lowlevel things. It is really about stepping on the toes of drm drivers and xorg drivers.
I wouldn't be surprised if the real regression between 1.0 and now is because ntoskrnl has been improved a lot.
