Hmm there might be another reason also. From what I read, theres 2 ways for a driver to work in WIndows, Kernel mode and User mode.
I think Kernel mode is faster then User mode, however user mode is more reliable when a driver crashes. In which case, the 950gma XP driver works in kernel mode, where as WDDM drivers work under user mode. On Sun, Jan 24, 2010 at 11:45 AM, Espionage724 <[email protected]> wrote: > Hmm...strange.
