> I wonder why they don't just call the game developers on the phone and say "here is AMD, you must fix your shaders, here is the code".

From my experience as a member of an away team, your own goals is not the home team's goals. Thus the home team has close to zero motivation to rethink their schedule and program just because someone else, who just happened to release their product, happened to find an issue that is only observed and reproduced in a very specific platform that no one uses (yet).

Who has all the motivation to see that bug fixed? The ones releasing the product. Thus, the fixes go in the driver, because that's the only thing in their control.
