CPR W3 on Hairworks(Nvidia Game Works)-'the code of this feature cannot be optimized for AMD'

Of course the other, largely unrelated, issue with this game sounds like it's the Watchdogs effect again. Or is it called the Aliens: Colonial Marines effect?

Either way, hair effects seem to be the least of the worries.

At least then Nvidia and AMD fans alike can unite against the console and the poor ports we so often get!

While I understand GTA V isn't perfect, I think we'd all rather a delayed PC launch that allowed for some extra tweaking to be done than something that look the same as the console version.

Out of interest, does the console version (of Witcher 3) have GameWork effects?
 
AMD have a tessellation level override cheat built into their drivers anyway so you'd assume that it would be a relatively simple fix if it was their GPU's choking under heavy amounts of tessellation. I think that's probably just NVidia taking the rare opportunity to highlight a much ignored inherent weakness in AMD GPU's.

Personally, I think AMD's lacking tessellation performance and the override cheats they are using to compensate should have been a bigger outrage than the GTX970 memory issue given that tessellation is going to be used more and more, heavier and heavier going forward but it mostly flew under the radar.

lol "cheats", an option that's visible to everyone in the control panel and the way you're getting on its some sort of super covert amd implementation that nobody knows about. Wind your neck in mmj literally all you bring to these threads is nothing but anti amd comments no-matter what. The rhetoric is a bit tired by now to say the least, dyed in the wool fanboy.

Every post of his is complaining about "AMD fanboys" too, lol!

Couldnt agree more.

When I first read what you said, I thought 4 times the throughput, rubbish there no way its that much better, then I went and looked at a benchmark or two.

Holy cow.:eek:

Ok so it's not 4 times better, but the premise is there. that is a significant improvement in tessellation performance.

Yes a 285 might/should very well do better in a hairworks situation, I wonder if Witcher 3 will have a benchmark feature ?

A 285 should show some improvement during a hairworks moment (god that sounds terrible :)), this is going to need some testing.

I made the mistake or going off AMD literature :o

Shaders for shaders 7950 its 2.2x ish, shows how bad it was, now on par with Nvidia.

Maxwell looks about the same relative to Shaders + clock rates,

The 290X has 55% more shaders and +8% clock rates vs 285, a 1000Mhz 290X Tonga revision should score about the same as the 780TI

it would be interesting to see how the 390X compares to the Titan-X

980: 2048 Shaders = 56000
Titan-X: 3072 Shaders (+50%) = 84000?

380X: 2816 Shaders = 53000?
390X: 4096 Shaders (+45%) = 77000?

If that's right tessellation performance between them is close enough not to make any difference in heavy tessellated games.
 
Its interesting to see how despite AMD's abysmal GCN 1.0 and 1.1 Tessellation performance they are still able to keep up 'roughly' with Kepler, is that all down to Tessellation driver tweaks?

Also, those Tessellation tweaks are available to the user in CCC, i wonder if they can be used to improve Nvidia's cited Tessellation performance issue in W3, if so why have AMD not done this themselves?
 
Good question.

We will have to wait for some bench numbers on Witcher 3 to see if it is anywhere near correct about the hairworks being mainly tessellation based, unless there is some other bench that can be run to see if it is the case.

Yeah, put it to the test, who here has this game, a 280/290 and a 285?
 
Just read this entire thread and I twigg its about Witcher 3 but CPR what is that? Someone need resuscitation?

This is common practice for Nvidia, same with their Gsync implementation whereas AMD's freesync

Quote"
G-Sync monitors require a proprietary Nvdia G-Sync scaler module in order to function, which means all G-Sync monitors have similar on screen menus and options and also have a slight price premium, whereas monitor manufacturers are free to choose scalers from whichever manufacturers produce hardware that supports FreeSync. "

"In order to be G-Sync compatible, the screens need G-Sync specific hardware that's rather expensive, unofficially adding around £75 on to the price of any given monitor. "

"FreeSync, which is an AMD technology, uses the Adaptive Sync standard built into the DisplayPort 1.2a specification. Because it's part of the DisplayPort standard decided upon by the VESA consortium, any monitor with a DisplayPort 1.2a input is potentially compatible. That's not to say that it's a free upgrade; specific scaler hardware is required for FreeSync to work, but the fact that there are multiple third-party scaler manufacturers signed up to make FreeSync compatible hardware (Realtek, Novatek and MStar) should mean that pricing is competitive due to the competition.

While DisplayPort 1.2a is an open standard that can be used by anyone, Nvidia's latest 900-series graphics cards don't use it, with the firm saying it's going to continue focusing on G-Sync instead. Some monitor manufacturers are sticking with Nvidia for now, too. "

So enlighten me, how is it that this is all AMD's fault? Why should they be claimed to be "whinging" its clearly Nvidia using anti competitive practices.

No matter how much of a fanboy u r - competition is a good thing. I've always been on the red team, and up until last 2 cpus in AMD's camp.
 
Some Tessmark scores on all 4 tests

I can not run the settings in the graphs (CPU bottlenecked) so I maxed it out @2160p with my cards @stock

Don't know how many cards it uses but it looks and runs very smooth.:D
 
Kaap stop showing off ^^^ :p

Make yourself useful and post one Titan-X Tessmark score at 1080P? reference clocks :)

Don't know what res they used, assuming 1080P
