No joy from Intel
About 15 years ago I worked for a graphics software co that discovered a bug in Intel graphics chipsets. Our drawing software used a command (new I think in Win98) to draw a rectangle with a single command. Our competitors continued to use the old method of drawing four lines in consecutive steps (automatically from the user POV, but slower). Intel hadn't implemented the new command so our software suddenly crashed if a user tried to draw a rectangle. Other less elegant applications worked fine. We of course were blamed despite our devs making a simple demo app whose only function was to draw a rectangle, crash and log the problem. Intel refused to talk to us even after the company sent a copy of the app on disk via registered mail. We sent out an upgrade that probed the hardware before deciding which command set to use, which would have slowed the operation slightly but fortunately not really significantly.
If your 'Intel Inside' PC suddenly goes 30% slower what chance they'll talk to you?
Glad I use Linux on AMD.
