Re: 'if you're stuck using proprietary drivers'

Gabe doesn't care about political purity in device drivers. He cares about performance.
If anything, Nvidia is in the drivers seat here because they have the best combination of silicon and drivers available for Linux. Anything involving Intel is a total non-starter regardless of platform. The hardware just isn't up to the job. AMD also has a chance to influence things because their hardware is not a joke.
Until AMD can provide a superior result (under Linux), Gabe will just follow Nvidia's lead.
