    Which is why you never buy a video card based on just one benchmark (or, indeed, one review). I think that's pretty much common sense.

    However, if you had been foolish and bought an NV30 class card, isn't it the least Nvidia can do to at least try and give you decent performance? Don't the end users deserve that? I find it a little hard to swallow that ATI fans want to deny gamers large performance increases based on the fact that maybe the game will be used for benchmarks (especially the same ATI users who vocally defended ATI when they did exactly the same thing with Quake 3).

    I don't think there's anything wrong with doing per-game optimisations as long as there is A) no discernible effect on IQ and B) there is a degree of openness about the fact that it's being done. Is it any different, really, than Valve working closely with ATI coders to make sure HL2 runs well on their hardware? Or Nvidia working directly with developers to help them write the most efficient shaders possible?

    All I'd ask is that if Nvidia are doing optimisations for one particular game then they should say so openly (same goes for ATI). However, if those optimisations are more generic then that's their business. Again, though, no one (AFAIK) has yet to prove Nvidia have done anything.

    fud is "fucked up disinformation", and disinformation is synonymous with lie; so sorry, but you do have to lie to spead fud.

    No, its "Fear, Uncertainty and Doubt" - you can create those elements without lying.

    Looks like English and German grammar rules are way more different than I thought.

    I thought there is a consensus that FUD means fear, uncertainty and doubt.

    doh, sorry about that; the acronym finder agrees with you. it also has the definition i gave but "fear, uncertainty and doubt" is the bolded one. i suppose i just got them confused because most of the fud around these days falls into both categories. :oops:

    OK, but the context of Carmack's remarks was the R4x0/nV4x on-site benches he conducted for D3. As well, Carmack didn't say "only nV3x," he said "especially nV3x", which obviously adds nV3x to nV4x in Carmack's "heavily optimized" category. To say that his case for nV3x was worse than for nV4x does not eliminate the intent to include nV4x. Isn't it already a matter of public record that while Humus' optimization improves performance for Rx0 it at the same time degrades nVx performance? Since the change Humus made is exactly like the kind of things modders will do, I see no reason to have to wait on those mods, as the only difference will likely be one of degree, with nV4x "falling off the fast track" to a more or lesser degree.

    I don't care what JC loves or hates and I don’t pretend to understand his feelings about things that he hasn’t commented on. You are taking this personal. The quote I was responding to was

    Clearly he does disdain those optimizations. I suspect he would hate them equally as well from either Nvidia or ATI, but again that’s not really in the scope of my response. I was simply responding to the quoted material that attempted to establish JC’s feelings on the subject of such optimizations as being indifferent when he took the time to address them and used the word hate to describe his feelings about said optimizations.

    Again I don’t give a rat’s ass about what Carmack loves or hates. Just as I don’t really give a rat’s ass which video card company makes the car that happens to be in my system, so don’t take my comments as a fanboi using the great JC to justify his video card purchase.

    Uh...OK...;)

    To me the issue was in pinning down what he said, especially in the context of what he knew about but didn't bother saying. To me, complaining specifically about ATi doing tri opts, but nobody else, when both companies are doing tri opts, was a very blatant, bizarre oversight for someone of his experience to have made. It certainly could not have been anything other than a deliberate oversight, which causes me to wonder that JC might have thought nobody would pick it up...;)

    Did anyone else notice "Today's date is Tuesday, September 31, 2004."? It's an interview from the future! Odd... my calendar shows that September has only 30 days and that the 31st (if there was one) would fall on a Friday. Maybe George Bush thinks he is Caesar and has to change the calendar? Will November become Bushember?

    Regarding the discussion comparing TV to a PC monitor. One big difference is that most TV programs are recorded on film or video. This means that motion blur is built in. You don't have that advantage in a PC game. Later they discuss motion blur, but it wasn't mentioned in the earlier discussion regarding televisions. TVs also have a low pass filter which helps remove aliasing, IIRC.

    One problem with the suggestion of changing quality on the fly is that it can cause framerate fluctuations and quality issues. For example, say you are just above the threshold for enabling feature X, but when you enable feature X, performance drops too much. You could end up ping-ponging back and forth which would be very annoying. Of course, you could try to catch situations like this, but it's not easy to cover every possible scenario.

    FUDie; It's like "The Twilight Zone" over there which could explain the date. :wink:

    The interviewer has been on about changing stuff on the fly for a couple of years. Seems to be his pet dream.
