That was very informative. I hope we can see some direct to metal programming on GPU's anytime soon

PC's don't use dedicated hardware. An API is needed.

7:00-7:45 was really interesting. According to John, the innefficiencies in texture mapping and texture replacing is a huge reason while PC development is more difficult and more innefficient, and also according to him drives have huge inefficiencies that, if ironed out along with good APU design on intel and AMD chips, could allow an integrated graphics core to run high end games. This is just his opinion and his prospective as a game developer... but that is huge. I really hope he is right and that AMD, nvidia, and intel figure out how to get the most from their hardware and drivers soon.

Both the interview and the ID software history video(s) were really interesting. I ended up playing quake II some after seeing it all, hahahaha. I admit that I don't get a lot of what Carmack was saying, but the general point seemed to be that he wanted something that works and works well with Rage. Just like Doom back in the day, it's meant to be something that can be both impressive and capable of running on most hardware today. It seems that he never veered from that stance since the 90s (well, maybe except for Doom 3 which couldn't be maxed when it came out....but I doubt Rage will either). I'm also curious to see what the next Doom is going to bring to the table after Id has had time to look at the ups and downs of the series.
Ummm....

still what ever APU comes your OS such as VISTA or 7 won't allow for low level code optimization to access a particular texture. Drivers are always on OS layer which is needed.

I cant wait to get into manipulating sub pixels and updating pixels through addresses. I bet you have to create multiple hash tables that store information based upon object locations to rasterize lighting and shadows.

Shame the interview is spoiled by the other guy 'ok, ok, ok, right, right, right ... ok ok ok right right right '.

Yet again proof that poor coding messes up with good hardware. It seems that AMD and NVIDIA have a higher jump in hardware compared to jumps in software. I hope they fix the issue with Rage he described.

Man its a shame to see that a lot of the issues with pc hardware is again going back to drivers. I hope one day companies ( nvidia and amd ) can iron this out to create a more efficient platform for game development.

What I found shocking was that he said Intel was on the right path. Considering the performance of such Intel IPUs, they are still levels behind in actual performance of the competition. Although they do fairly well compared to other low end solutions in its price range, you can grab a GTS 250 or even a 8600GT that would walk over what Intel has to offer. Heck, my ti4200 in on par with the Intel HD in this tablet.

He sure is right on Intel drivers. The IPU only does well in selected games, but no where on a universal systems. Sure, I can game CoH on low settings, even low + DX10 lighting, but the moment I play CS1.6, is brings the entire rig to its knees.

AMD, regardless of the label of APU, is still geared towards 2 independent units. AMD is aiming to go such routes, but it is still no what a true APU is.

My half-boiled understanding of this talk agrees with you? Sure yes biggrin.gif!
