True... considering HL2 isn't even available yet it's pretty silly to start complaining about it's performance with the FX already

performance isn't the issue; the HL2 beta runs more than fast enough on my 5900, but there are shader problems which cause crashes and degrade image quality

There is a flaw in nVidia's pixel shader 2.0 architecture and consequently causes a cascade effect in certain dX8 games because of backward compatibility problems with pixel shader 1.2 based code.
Certain dX9 shader code is also incompatible with these chips which means a lot of new software will not work correctly. This problem looks set to be present in nVidia's PS3.0 technology as well, so the 6800 has the dX8 cascade problem, and will most likely have problems with upcoming dX9 releases as well.

there is no fix for this - it is a hardware problem

whats that smell? smells like grade A bullsh!t to me.

*reloads rifle*

also i remember a week ago that ati got caught by microsoft about its implementations of instancing. i believe microsoft has thoroughly checked out shader model 3.0 as implemented by nvidia to see if it checks out as far as standards go. and since microsoft hasnt told nvidia to change anything they seem to be doing everything according to specs.


btw when we say links, we dont want links to some unknown person on a forum no one has heard of stating that nvidias implementation is fooked. give us a link to a respectable site. (btw that eliminates the inquirer as well )

i didn't come here to get into an argument, you can believe what i said or not, i don't give a **** - but the problem exists (it is more apparent on slower cpus).
pandora's box - number of posts is not proportionate to iq, thankyou for proving that.

maybe in a years time i will be posting 'i told you so' on this board, but i sincerely hope not because i want the 6800 to kick ass, ok?

but for now, there's nothing you can say that will change the fact that there are major issues with the current FX family

im not calling bs on the fact that the FX line has problems. just that when u stated it also applied to the 6xxx line i have a problem.

morbias, you said you didnt come in here to argue, yet the point you brought up is very obviously flameworthy material...

No personal attacks though. Got it?

/me moves on... only to pop back in later to make sure no threadclowns have deteriorated this thread...

[morbias]

fair enough, but the 6800 shaders would appear to have been built along the same line as the version 2.0s, as in certain instances they display the same slowdowns and corruption when running dX8 code as the current FXs, which may culminate in similar dX9 shader support issues.

[morbias]

LOOK the details i posted were to help people out who may have been having those problems.
the idea that ppl come to a discussion forum but don't discuss problems because someone might disagree is a little thin imo.

btw, i heard last year sometime that 5900s have 3.0 support also, but there is no software or driver that activates it. does anyone know more about this?

yet again you dont provide any proof that the 6800 shaders appear to be built along the same line as 2.0's. where are they showing slowdowns and corruption?

[morbias]

try running a 6800 on a 2Ghz cpu, in games such as Asherons call 2, nfs underground, or f1 2002.

i can't provide proof, as i have only read of these problems in forums and obviously forum links aren't always solid. nVidia has not released any information on the problem - but then why would they if there was a serious flaw in their hardware.

please realise that these corruptions and slowdowns happen seemingly randomly and so are hard to replicate on certain setups. a slower cpu does however seem to increase the probability of it happening
