Damn, so now with my 960 I cant post in AMD GPU threads, what a shame.... Oh, wait.
The "fix soon" is just an option that will let the game detect if you have a Kepler card, downgrade Tess to x16, and be done with it. "Fixes" from NV these days, you know...
So in other words, Kepler was neglected
I hope my 880M sees an increase, looking forward to it. Get to work Nvidia
So there's something that Maxwell cards can do better than Kepler cards. Ok, I can believe that, now explain the Hawaii performance.Interesting. The Nvidia person quoted doesn't give any detail about what "couple of issues" are and how much performance benefit to expect, and that's probably for the best. I honestly hope that Nvidia improves performance with Kepler in TW3 back to a point where it's more properly competitive with Maxwell and GCN cards. ^_^
Either Kepler was neglected, or The Witcher 3 has features that just play to Maxwell's strengths and hits weaknesses of Kepler. Hopefully for Kepler owners it's the former, and Nvidia is able to improve performance for them. I'm not in the tinfoil hat camp of thinking that Nvidia actively crippled Kepler performance for TW3.
There is some kind of driver fix coming.

He does make some very great points. If NV worked on the game so closely with the developer for more than 2 years, and it knows the entire GW source code, shouldn't they have been able to catch the issues of Kepler GPU performance throughout testing? I wonder if it wasn't for all those fans complaining on various forums/GeForce that NV would have even bothered. This is very reminiscent of NV re-enabling mobile GPU overclocking (temporarily) but only after thousands of fans complained online. Hopefully the new drivers are out from both AMD and NV and there is a nice showdown comparison between 980Ti, 780Ti and Fiji come next month.
Nvidia outta include quality levels on hairworx, or be able to force them in control panel.
What if I only want 16x tessellation on my 970 to save some frames. I read an article that states it would look exactly the same and 64x tessellation is redundant.

The poor Kepler performance has nothing to do with tesellation. In fact the performance hit from enabling Hairworks + HBAO+ is actually a bit lower on Kepler GPUs. A lot of people seem to be overlooking this...

780 Ti - 34 FPS avg with GW off, 26 with it on - ~26% difference
980 - 46 FPS avg with GW off, 33 with it on - ~32% difference
So as you see, Kepler takes less of a perf hit from enabling GW features...
We're in uncharted waters here. Nvidia released 2 new architectures on 28nm. Of course they were going to do everything they could to make Maxwell look appealing. Either that, or Kepler was a shit architecture and AMD are the ones who know what they are doing.
So in other words, Kepler was neglected

780ti owner remaining skeptical... Bought nvidia due to perceived good drivers support, should have stuck with my 7970!

This all started in a Witcher 3 thread on the nvidia forums. Kepler performance in witcher 3.
It is not the GW features, already debunked on page one
Here->
From looking at that gtx 970 review from 5 months ago, it looks like gtx 780 ti is ~ 47.8% faster than 7970 at 2560x1440.
Oh, crap...that's one card every 1.5 yrs...and I've had the 7970 for 18 mos. MUST...FIGHT...URGE...TO UPGRADE...
I believe Maxwell (because of its 128core SM layout) is just better suited when it comes to game engines built around the GCN architectures that are in the consoles. I believe it to be a scheduling issue, the 192cores of the kepler SMX all use the same cache/L1. Maxwell divides more evenly with its 128SM which is made up of two 64core blocks that share resources (cache/L1). If you know the GCN architecture, look at maxwell and kepler.....
Kepler and its 192core SMX is the odd ball. I believe it is just a matter of scheduling.

Maybe I'm not understanding this correctly but are you saying people must own the hardware being discussed or they are not allowed to participate in said discussion?If you own hardware that uses the driver, you are welcome to be a part of that conversation. If you don't, you have no business, and you're derailing it.
Understand now?
