Hellbinder says full trilinear would cost 50% preformance?

Re: Hellbinder says full trilinear would cost 50% preformanc

Haha. Hahaha. HAHAHAHAHAHA!

Hellbinder knows very little. His "technical details" are often nothing more than FUD. If HB says something, believe the opposite.

 

Then educate us if Hellbinder knows so little.

How much of a performance hit will ATi take with adaptive AF disabled. Inform us all with your superior knowledge.

 

I don't think there is any proper way to nail down a number, it will depend totally on the situation and what game is tested.

 

The issue at hand is adaptive trilinear. Dave quoted as little as a 2% hit, whereas computerbase showed a larger hit with--but with coloredmips, which may make for an invalid comparison (though the 9800XT score didn't change, whereas the X800P score dropped).

 

Might have missed it, but did Dave mention where and how his 2% were obtained?

 

Which game did computerbase use?

 

Re: Hellbinder says full trilinear would cost 50% preformanc

I think hellbinder was right on the money with the X800 Pro. It was MUFU and others that where out to lunch.

 

First of all, all anisotropic is adaptive.

Anyway, it really depends on the scenario, but all you have to do is look at benchmarks. The performance hit typically seems to be ~20% for disabling the "trilinear optimizations."

 

We used UT2003 as an illustration, because it is widely used as a benchmark. We did, of course, confirm a perfomance drop in similar orders of magnitude on other games as well (Delta Force BHD, Call of Duty etc.).

 

Mayeb HB meant there is a 50% hit when doing full trilinear at 16x AF?

 

Re: Hellbinder says full trilinear would cost 50% preformanc

Yeah but sometimes I say stuff that's deliberately wrong to keep everybody (Edit - especially nVidia) on their toes and I never let out the whole truth until after the release. You see... the R420; sometimes it's 8 thingies, sometimes 12 thingies, sometimes 16 thingies; it depends which level of forum mentality you subscribe to and what you think a "thingy" is. Me? I don't really know... but I have to say something instead of "I don't know", don't I? That'd be insane.

L.M.A.O.

So in other words, We cant take you seriously all the time either. :?

 

Re: Hellbinder says full trilinear would cost 50% preformanc

To play devil's advocate, it sounds like he's talking about games in the future (at least, that's what the first sentence of that paragraph suggests). Doesn't mean he can't be offbase about the future games either though 50% is a rather large number...

 

Re: Hellbinder says full trilinear would cost 50% preformanc

Perhaps, but he just has no idea what causes the performance hit of trilinear filtering. In the future, as games start to have more pixel shader instructions per texture call, hardware should have an easier time increasing trilinear performance without resorting to questionable optimizations.

I don't believe there is much of any correlation between complex scenes and high degrees of anisotropy, either. I would tend to think that simpler games would be more likely to use higher levels of anisotropy (i.e. flat floor/walls stretching far into the distance, as seen in Serious Sam).

 

I'm sorry, when someone mentions Hellbinder, I think back to when he mentioned that "R360 has the best feature ever OMGLOLZ!!!1111one" (referring to Overdrive, if you couldn't figure it out). I can't take him seriously.

 

And hence, Hellbinder is a rabid fanboy who hears a few very vague rumors, spices them up with his own insane ideas without mentioning that, and then capitalizes random words.

 

No,,, I dont think so,,,

I Think if you look back at hardware that did Actualy Full trilinear with no performance hacks at all it was nearly a 50% hit. Furthermore as i mentioned as scene complexity increases Full trilinear will get more and more expensive.

So laugh if you want. I dont mind. 8)
