A client of ours is having a problem panning on a mapping application that we write on their panasonic toughbooks (CF-19's).

One of their toughbooks the panning is fairly smooth while on the other it is really slow. Doesn't help that they have all the settings turned up, but I would of thought any reasonably new graphics card (even shared memory) would have more than adequate graphic speed.

I am pretty sure that the graphic adapter is to blame, but I can't find anything out about either chipset (level of acceleration, non-problems, etc). All I get is the intel data sheets.

The faster panning one is on the Mobile Intel 4 Series Express Chipset while the slower is on the Mobile Intel 965 Express Chipset.

Is this expected? Does it sound like a driver problem? They both have the same amount of ram and same cpu.
