Not only is the man the chair for the OpenCL group but the President of Khronos and somehow this is misleading to you?

Above . Bingo . Lets wait alittle while here and see whos Gpus Apples uses in 2010. I bet it isn't NV . It doesn't matter who is on the dam chair , Apple took open cl to Kronos as a new standard. Its Apples baby all the way . Nv guys tring to say open Cl is a NV thing is because They no cuda will be doomed because OF APPLES open CL tm. They want to glorify NV for bringing forward open CL when its in fact not true. You guys really should look into how long Apple has been working with Power VR on a new open standard LOL.

Alot longer than people would believe according to other reports. Intel same thing Atom is going SOC with Power VR. Power Vr has a working multi core design now that also uses open CL . Man that was quick for a just released standard. But Apple knows what there doing. Of course Atom will use Intel gpus also . Thing is the Apple SOC Power VR chip won't show until 2010.

And why not?
Apple has long used both ATi and nVidia products, depending on the needs of particular products.
Now that they also make iPods and iPhones, PowerVR products also get interesting.
I don't see why Apple WOULDN'T use nVidia GPUs in 2010. Obviously not exclusively, but Apple has never exclusively used a single brand of GPUs. Which is also the reason why Apple was interested in an open compute standard. Just like Microsoft added Compute Shaders. Microsoft also wants their software to work on all GPUs.

Sure there must be more than one game supported. :D Which of course was the point of that article - maybe next gen will be able to support physics and be realistically useful at the same time. Won't come too soon for nvidia.

Yes, yes. Of course. It'll be useful when GPU accelerated Havok is launched. We know. ;)

This document may be a bit misleading as this is Mr. Trevett's bio from here:
http://www.khronos.org/develop...ary/bios/trevett_neil/

Trevett, Neil - Vice President Embedded Content, NVIDIA

Neil Trevett joined NVIDIA in May of 2005. As Vice President of Embedded Content, he is responsible for enabling and encouraging compelling applications on non-PC platforms, including cell phones and automobiles. Prior to joining NVIDIA, Mr. Trevett has spent over twenty years in the 3D graphics industry including Vice President positions at 3Dlabs. Mr. Trevett is currently the elected President of the Khronos Group where Mr. Trevett created and chairs the OpenGL ES working group that has defined the industry standard for 3D graphics on embedded devices. Mr. Trevett holds a Bachelor of Science degree in Computer Science and Electronic Engineering from the University of Birmingham in the UK. (Permalink)

Mr. Trevett may chair the OpenCL group, but his main focus within nVidia and the Khronos Group has been embedded platforms and not PC platforms. OpenCL has applications in the embedded field as well as PC GPU applications. Then there is Apple, which holds the trademark for OpenCL and initially proposed and did the final editing for the current OpenCL standard.

So I take it that when the OpenCL group meets, Mr. Trevett sits there and snores in his chair.

im posting from a psp. nvapi implementation of dx10.1 fsaa is lower quality compared to the real deal. see the stalker cs fsaa comparison at alienbabeltech. i laugh at the half baked nvidia implementation of it. mirrors edge is coded in a way to affect performance when physx is used on the cpu. i had the same issue of massive slowdowns after the broken windows and the game uses only one core.

It's about as "funny" as you lying dormant for five years and then suddenly deciding to surface in this thread and rack up 142 pro-PhysX posts in just a few days.

If you want people to stop questioning your credentials, it might be a good idea to offer the same courtesy to others.

Nonsense. The whole point about the DX10.1 feature is that a developer can read back the multisample buffers. The feature itself doesn't perform AA, and as such has no effect on quality.
If there is a quality difference at all, then this is because the developer chose to implement it that way.

Thing is that I don't randomly go stalking people on other forums and troll them.
I've responded to everyone equally, didn't bother them outside this discussion, and I've been honest and factual, backing up my posts with relevant information and links where possible.
And again, I'm not pro-PhysX, I'm pro physics-acceleration.

Need I remind you that a moderator just asked everyone to stop throwing insults and jabs like "fanboy" around?
You questioning my credentials and calling me pro-PhysX is EXACTLY that.

BFG, I didn't see Scali question anyones credentials. Only noted that melted Rabbit suddenly appeared on two forums to bother him. Sounds like he may have a stalker! LOL. Your post was more "accusational" than anything Scali posted. Go Figure.

I see. So questioning someone's credentials is okay, as long as you?re the only one doing it. But as soon as someone does it to you, they shouldn?t be attacking your character but instead should be sticking to the topic at hand?

Need I remind you that a moderator just asked everyone to stop throwing insults and jabs like "fanboy" around?
Right, which is why I suggested you?d better stop posting comments like ?Funny, suddenly there was a "MeltedRabbit" who started bothering me on Beyond3D aswell.

Are you following your own advice and sticking to the topic at hand, and not engaging in character assassination? Given you referred to this person as both a troll and a stalker, I somehow doubt you?re practicing what you preach.

You questioning my credentials and calling me pro-PhysX is EXACTLY that.
And what have you been doing the entire thread? I?ll cite one of your numerous examples:

I didn't question his credentials, I just stated a fact.
If you said "Well you've been registered for 5 years before you posted on this forum" you were stating a fact (I just looked it up, I seem to have registed back in 2004 because I posted something on an IT article, the forum account was apparently a 'side-effect'. Everyone happy now?).
If you say I'm pro-PhysX, you are not stating a fact. That is attacking my character.

It's not an insult, it's a fact.

I stick to facts. It is obvious that the person "MeltedRabbit" specifically looked me up on Beyond3D and made some snide remarks and tried to make me look bad in a discussion I happened to be in at the time (which had nothing to do with PhysX or GPUs in general).

I on the other hand have repeatedly explained that I'm not pro-PhysX or pro-nVidia, and refuse to be accused of either, they simply are not facts. Besides, even if I was, how is that relevant to what I say? I state facts, they are either true or false, regardless of whether I like PhysX or nVidia. That is why it's character assassination.
Just stick to the facts if you disagree with me. Don't make it personal. I don't make things personal with others either. Thing is just that "MeltedRabbit" did when he started bothering me on another forum. Had he not done that, then I wouldn't have mentioned it here either. It's a consequence of his action.

If I recall correctly, he himself admitted to not being a developer. So I stick to facts there. I'm not implying that he's not a developer, I'm just going by what he said earlier.
Asking him why he thinks it is possible to improve games in the way he suggests is just a normal question. I simply ask him to back up what he claims.
I see nothing wrong with that. I think I've backed up everything I claimed, and if I haven't, I expect people to ask me to do so aswell, which I gladly will. That's just how a mature discussion works.

Besides, it's still a fallacy. Even if I *did* question someone's credentials, that doesn't mean that I should have been doing that, let alone that it is an excuse for everyone else doing that.

I can hardly believe what I'm reading now. Are you doing this on purpose, or do you actually believe the rubbish you?re writing?

If you said "Well you've been registered for 5 years before you posted on this forum" you were stating a fact.
Much like when Modelworks pointed out you don?t have experience with engine licensing, yet you responded that he was attacking your character.

Modelworks was just stating ?fact?, was he not?

It's not an insult, it's a fact.
Modelworks was just stating ?fact?, was he not? It?s a fact you have no experience with engine licensing, is it not? You stated this fact yourself, did you not?

Answer the question: are you sticking to the subject at hand or not?

When you said: ?besides, what I do for a living has little to do with whether or not the things I say in this thread are correct?, the same applies whether that guy follows you around on different forums, does it not?

Why don?t you take you own advice: ?stick to the subject, rather than going for character assassination??

I stick to facts. It is obvious that the person "MeltedRabbit" specifically looked me up on Beyond3D and made some snide remarks and tried to make me look bad in a discussion I happened to be in at the time (which had nothing to do with PhysX or GPUs in general).
Nice backpedal. You stated you wanted people to stick to the subject, rather than going for character assassination. Now you?re saying you want facts. Well, you can stick to facts and still not practice what you preach, which is exactly what you?re doing.

Furthermore, when you engage in your character attacks, you refer to them as ?facts? and ?consequences?, but when others do it, you call it ?character assassination?.

I on the other hand have repeatedly explained that I'm not pro-PhysX or pro-nVidia, and refuse to be accused of either, they simply are not facts.
Why aren?t they facts? Because you said so?

Besides, even if I was, how is that relevant to what I say? I state facts, they are either true or false, regardless of whether I like PhysX or nVidia. That is why it's character assassination.
Exactly the same applies to MeltedRabbit, does it not? What forums he posts at is irrelevant to whether he?s correct.

Thing is just that "MeltedRabbit" did when he started bothering me on another forum. Had he not done that, then I wouldn't have mentioned it here either. It's a consequence of his action.
LMAO, ?a consequence of his action?. What if the responses against you were ?consequences? of your actions?

Again, why can you decide on these ?consequences?, but no-one else can?

If I recall correctly, he himself admitted to not being a developer.
You also admitted you didn?t work with licensed engines as well, yet you took offense when Modelworks pointed this out. You claimed it didn?t matter because you still could be right. So why question if he?s a developer given he could still be right by your own reasoning?

Again you?re not addressing his argument, you?re attacking his character under the guise of ?fact?.

So I stick to facts there. I'm not implying that he's not a developer, I'm just going by what he said earlier.
Again do you actually believe your hypocritical arguments, or are you doing this on purpose?

Here are some more gems from you:

05/18/2009 10:18 AM

So don't come here insulting me. I'm probably a more experienced engine developer than you are.

You sound like SunnyD to me. You think you know a few things about programming, then try to bluff your way through.
Those are all ?facts? too, are they? The word ?probably? now refers to fact, does it?

Or are they just ?consequences?? :roll:

This just looks nasty bad when people wearing mod badges, even if they claim to operating as off-duty officers while doing the beatings, pile into forum posters. Wow this looks ugly in here.

Surely 100% of these last few posts could have been taken to the PFI?

I've said my piece, so I?m done.

I saw the barrage of complaints coming from Scali about ?character assassination? and ?attacking people?s credentials? in his posts, but when I started digging through the rest of the thread, the hypocrisy of those comments was simply amazing.

I?ve probably done wrong by going off-topic, but Scali is hardly as blameless as he appears to think he is.

Just because I've never licensed the UnrealEngine doesn't mean I don't know anything about engines or licenses in general.

I wasn't drawing any conclusions from the fact that he followed me on another forum. I just stated the fact, nothing more.
Unlike Modelworks trying to jump to conclusions and trying to assassinate my character on the weak basis that I don't license the UnrealEngine (which is rather obvious, since I write my own).

So I didn't stick to the subject in a one-line post. Big deal.

Exactly, when there aren't any facts, and it's all conjecture, then it's character assassination. That's the difference.

Originally posted by: BFG10K

Pretty much yes. Pro-PhysX or pro-nVidia are very subjective notions anyway. They don't really serve a purpose. They do tend to have a negative undertone however when people accuse others of such. They do that to discredit them.

If I say blue is not my favourite colour, then you'll just have to take that as fact. Only I know what my favourite colour really is. You can tell people it's blue all you want, but there's no way you can ever prove it. You'll just look silly doing so.

I never implied otherwise.

Well I can easily see how me saying that MeltedRabbit posted on Beyond3D is a consequence of him posting on Beyond3D. I'm not jumping to conclusions.

I don't see how me being labeled pro-PhysX or pro-nVidia is a consequence of anything I said here. I never said "I'm pro-PhysX" or "I'm pro-nVidia", in fact, I stated the opposite on various occassions.
So it can't be a consequence of my actions.

Originally posted by: BFG10K

That's because it's wrong.
I don't work with UnrealEngine, but I DO work with licensed software. I write licensed software for a living.

Originally posted by: BFG10K

I didn't question if he's a developer. I questioned whether he had anything to back up his claims. If you don't give any arguments for things you say, then how can you have a discussion?

Originally posted by: BFG10K

Not everything one says is fact. Things can also be opinions. The word "probably" implies that I am speaking my personal opinion, I don't try to make it look like fact.

Now, who do I address when a moderator harasses me?

I thought you were comparing the NVAPI extension to read back multisample zbuffer vs using DX10.1 to do the same?

so that means that d10.1 benefits stalker cs with higher fsaa quality and fsaa in alpha textures in the unigine graphics engine. something that nvidia cant. performance improvements and image quality can be seen. unlike physx which is a gimmick which impacts performance and do unrealistic phisics simulation like the ice breaking in cryostasis or the flags in mirrors edge

No it doesn't, because nVidia offers an extension to do the same thing as DX10.1 does.
Why do I get the distinct impression that you don't have a clue what you're talking about?
Everytime I try to explain, I get a response from you that makes no sense whatsoever.

copycats will never beats the original. a sacrifice in image quality is done to emulate something that u dont have. the nvapi implementation of dx10.1 aa is a propietary extension which will die like sm2.0b geometry instancing, truform and soon physx.

Multisample buffer readback is NOT AA.
