Wow that didn't take long to turn into a fanboy fight, largely started by the Nvidia guys all having a go at Charlie for being petty. You'd have a point if they said Nvidia's dad smells, but he didn't.
Its pretty simple, he doesn't care about OGL 4.0 support, he doesn't care when its available, its got smeg all to do with AMD having a beta driver out.
THe issue is Nvidia made a whole huge deal about how they'd have a 4.0 supporting driver at launch, they went on and on about how AMD don't support 4.0 yet, and Nvidia will the day their hardware is available.
Try and put two and two together, if Nvidia said they'd try their best to have full, or beta support on launch, thats one thing, but when they PROMISE something while throwing it in the "AMD don't have it " list of reasons their hardware is better........ then they completely fail to actually provide it, its bloody funny for any non Nvidia fanboys to stand up and laugh at them. Another attempt to claim how much better they are, failed miserably.
Its not what they failed to deliver, and its not the date, its the way Nvidia yet again promised something, like Fermi's within a month, last October, that is the point.
If Nvidia were ever just honest, no one would bat an eyelid, its the ridiculous lying and incompetance that tends to get on everyones tataa's.
Then theres mocking AMD for having a not great beta 4.0 out already, when they haven't made any promises and are just getting it going, and barely working beta's is where support starts. The first beta of any new API is going to be bloody horrible, because companies can't start to try and support it, till its available, and till its available and companies start finding bugs and things they need, AMD can't start working on those things.
