What are you then ^_^
AMD Say Nvidia "completely sabotaged our performance" with HairWorks
- Thread starter WYP
- Start date
What are you then ^_^

I though you might not be being entirely serious but wasn't sure. Sorry, wasn't a shot at you, more dissolution with gaming as a whole whenever a new game is released and that quote encapsulated it well. It seems to be a never ending recycling of faux outrage at "X game has been nerfed for consoles!" or "Why isn't this perfectly optimised for MY hardware?"
Its also been one of those days, and I'm in one of those moods, but it's Friday so there's that.

That's Nvidia's fault. It's open software. After a few driver updates in Tomb Raider Nvidia cards did better with TressFX than AMD did. With Gameworks it's not like that. AMD can't look into it and help their users get better performance.

I remember NVIDIA blaming amd for bad performance with TressFX turned on, while they had refused to get the API to work on their cards correctly. I think we are crying over spilt milk. nothing will happen eventually

Physx, HBAO+, TXAA, MFAA are all Nvidia exclusive, Why aren't these being moaned about constantly ?

Well PhysX can be handled by a quad-core cpu. HBAO+ noticeable yes, regarding the AAs, it doesn't really change much how the game looks to the as much as hairworks

Try using Physx at the maximum setting in Arkham Origins and not get lag with an AMD GPU, It's impossible even with a quad core.
On an Nvidia card no lag ergo why aren't people moaning about that ?

Now, AMD did push Nvidia to focus more on hair simulations with the release of TressFX. Nvidia pulled out the unpopular HairFX from PhysX (LMAO, pull their hair out) and spent their resources (money too they say, but of course both side's engineers aren't working for free, perhaps they meant handsomely) to develop an improved version with new implementation technique by using tessellation and LOD control, then call it HairWorks and put it in GameWorks as an exclusive game developer's library (meanwhile, PhysX with basic physics simulations is open source now). TressFX and HairWorks use almost the same basic physics properties (density, clumping, wetness, etc) and physics simulations (various dynamic forces like gravity, wind, etc, shape preservation, stiffness, etc) but they use different implementation of technology in doing it. Of course they optimize it to their own hardware, heck, the way they want to implement certain technique might even be so influential that it affects their hardware design (eg. CUDA core origins was Ageia's PhysX PPU).
I don't know who claim "sabotage" first, I just know that the fender benders are mainly because of technology implementations. TombRaider with TressFX: the fix for Nvidia is not revealed but could be ambient occlusion for each of the thousand of hairstrands (have to do with their tech on doing TressFX), Crystal Dynamics was working with Nvidia released a patch. Batman Arkham City with the hero's tessellated-heavy cape: the solution is to lower the tessellation option in-game or in Catalyst CC.
And now... Witcher 3 with HairWorks. HairWorks is not part of PhysX but part of GameWorks and it's not specialized to Nvidia GPU, any GPU with tessellation power can run it.
One more thing to note on PhysX. Not all PhysX is Nvidia PhysX, that is hardware-accelerated physics-simulations that require Nvidia GPU. Basically, you don't need an Nvidia GPU for PhysX unless you want the hardware accelerated features. Physics like collisions, rigid bodies and many others need only CPU to process and what with multi-threaded ability in PhysX version 3, today CPUs are strong enough to handle them. Physics effects that use particles (debris, smoke, etc), deformables (clothing, flags, etc) and fluids (water of course, with different viscosity) utilize hardware acceleration and that means exclusive to Nvidia GPU.
Oh, and if you activate PhysX Indicator and play Witcher 3 it will show that PhysX is using CPU.

Not sure if this has been mentioned, but didn't AMD pull the same trick with Tomb Raider and their TressFX tech?
edit - Looks at post above mine and see's the exact thing I mentioned

PhysX was always for Nvidia only. You can't run it on AMD GPUs. That's why it "lags" because CPUs aren't really good at processing PhysX.
All of the other stuff you mentioned aren't Nvidia exclusive, AMD can still use them. I just turned HBAO+ on in Witcher 3. Works
Seriously though, never had a problem using any AA and they all look the same anyways or so subtle a difference you would have to stop and stare. Just some are more efficient than others is the biggest difference. That's why no one cares to moan about them. It's not that big a deal. Gameworks is a big deal. It's not the implementation that's the problem with me, it's the concept and idea behind it. If AMD did this everyone would try to rip their hearts out for the same reason. But won't happen because 76% of the market is biased towards Nvidia. A few are exceptions, but, still got more than 2/3 biased.

AKAIK TXAA isn't even selectable on AMD cards is it ?
When I played Arkham Origins with a 290X TXAA wasn't selectable.

Not sure.. don't know which games that use it? If I knew i would check. Think Skyrim has it but Skyrim is literally broken for me so can't try that one.

Skyrim is working fine for me, you might just have a bad install or something

Nope. Even reinstalled Windows. Still won't work. Pretty sure it's steam screwing up somewhere during download.

I'm guessing tho other games are installing fine tho
