Oculus Employees: "Preemption for context switches is best on AMD, Nvidia possibly catastrophic"

it is not important to nvidia buyers, since nvidia trained them well to upgrade every year ;) nvidia has broken async shaders in maxwell, and VR hardware is kinda weak? No problem, you just need to upgrade next year to next gen cards which will have everything fixed for you :D Yeah, consumer friendly.

But yeah, regarding DX12 adoption rate, it does make sense what you are saying. all the previous DX versions were exclusive to new cards, thus longer adoption rate.

Why must everyone be put in a camp (red or green)? First off, nobody knows what is what with ACE and Nvidia but time will tell. Nvidia will release new GPUs that AMD owners are able to buy and vice versa. Nvidia have not trained people, AMD have not trained people and people can buy whatever they like. If VR (Oculus or Vive) is rubbish and gets really poor performance on DX12, I will buy whatever GPU is best and available at the time as I have a big interest in VR.

My personal thoughts are ACE is broken at driver level and will be working fine by the time the first wave of decent VR and DX12 titles are out and I expect it to be fixed. Also regardless of anything, I will be buying Pascal and Greenland and keeping which ever performs the best.

It is statements like yours that stir crap up and that isn't needed here.

Well Thief was the first mantle game title used Async compute to unleashed full power of 290X with 352 commands (44 CU x 8 ACE) but after Nvidia DirectX 11 wonder driver, GTX 780 Ti outperformed 290X easily. A 980 Ti is over twice performance put 290X to shame in Thief's mantle async compute.

I don't think so

On the Thief bench

290Xs 4 up are faster than GTX 980s

Fury Xs 4 up are faster than TitanXs.

Hey, I am not the one with unlimited money pockets saying that dx12 is not important, current gen is not important and by the time it gets mainstream we all be sitting with brand new next gen cards. I hear this argument specifically from nvidia camp, thus green and red camping ;)

yes, I will be sitting with next gen card, you will, kaapstad will and few other will, but the rest of the people will try to use their older gen cards to the fullest. While it is meh for you, but for the rest of the people it is major concern when nvidias **** is not working on current gen cards.
I never heard this type of argument from any of AMD users, since they use cards as much as they can, and most of the time they are able to do that, while nvidia users are being shafted.
I remember the days when 780ti was faster than 290x. What is the situation right now? 290(non x) is now competing to 780ti, while 290x/390x rebrand is closing down to 980gtx. I remember the days when 970gtx was direct competitor to 290x, what is happening now? 970gtx is left behind by 390(x)/290x etc.
I am living the days when fiji is direct competitor to titan x and 980ti, and I do believe come early next year that will be no longer a case.
So green red, doesn't matter I just respond to green people comments that's all ;)

THe minimum they could do with Mantle was not use it at all... game devs did use it thus they didn't do the absolute minimum thus you're talking rubbish... again.

Adding support to multiple engines isn't the minimum possible, learning how to port a game isn't the minimum possible, learning to rewrite the engine to take control of memory management and changing how you do things isn't the minimum possible.

As Johan said they were required to rewrite how the game dealt with memory to better use Mantle/any low level API, they didn't but in learning and playing with Mantle they learned what they'd need to do with the NEXT game for ANY low level API. This effort then will mean the next game is designed with this fundamentally in mind. BF4 didn't launch with Mantle support, it was added in during the Mantle BETA so they could learn what needed to happen for their next games to come to PC completely designed with a low level API in mind.

Certain people never quite cottoned on to this, it was in beta, the games weren't perfect under Mantle. The idea was for devs to spend a few months added Mantle and working out where their engines and games need to be improved for in 1-2 years time when their games will come out with the default rendering path being a low level API. So in Johan's case, he added Mantle support to the engine in general, got BF4 working with it and spent months working out what changes he'd need for the next games and where to tweak the engine to maximise performance and usage for the future.

I think you are the one who is misguided.

I am still waiting for decent C/F profiles in some Mantle games, what happened there.

The games devs also got a huge amount of publicity by announcing they were using Mantle and hence increased sales. So yes they made money out of Mantle but did the minimum to use it properly.

And I think I am like most people who buy a game, I really want it to work properly and not be a test bed for some game that was supposed to appear in a couple of years time. Even more comical is the future for Mantle is about as good as it is for the Dodo with the arrival of DX12.

Kaap, with BF4 testbed, I got 40fps increase on my 3930k/290x with Mantle (from 80fps dx11, to 120fps mantle).
I would love any testbed be like that :D
Mantle was short term plan to push LL API, that's all. Now we have DX12 and Vulkan taking over, Mantle is internal VR API.

And talking about test beds, you are a testbed for nvidia gameworks, aren't you? Every recent gameworks titles was a major bugfest on release, be it gameworks related or not, but still major bugfest. How does that work in your books? gets a pass? While nvidia 'helps out' to fix the issues.

And Mantle as a selling point? :D With AMD marketing...

I have always found with SLI the cards much preferred Gaming Evolved titles as they tend to scale better than Gameworks lol.

And another quality mess you missed off your list was Mordor Middle Earth which took ages to get a decent SLI profiles and even now Quadfired Fury Xs can run it faster.:eek::D

I am broke bud :D The way I see it is an enthusiast forum like Overclockers suck people into wanting (not needing) the next thing. I watch many people like me buy hardware they don't need, ask advice on what to upgrade to etc, even though they don't need to, so I have a different train of thought here. But I take what you say on board for the general populace of gamers and you are quite correct.

Having owned several cards from both vendors (680s/7950s/Titan/290X/970/Fury X/Titan X), I genuinely feel that for the most part, they are all pretty much a muchness and put them in a machine and put a game on that was the top game at the time of release for each card, you won't be able to tell which is which (unless you are using G-Sync/Freesync it seems) but with this latest news, I can see people having concerns on whether their current GPU will be good for DX12 or VR and hopefully nobody will need to upgrade.
 
I would suggest that anyone who is worried about changing graphics card because of cost should steer well clear of these first gen VR headsets anyway, they aren't really ready for prime time and the 2nd gen ones will be close behind with a number of improvements

if you aren't willing to sell and upgrade your GPU for a few hundred quid, then don't waste a few hundred on a VR headset that will also need replacing within a year

by definition the people buying gen 1 VR headsets will be enthusiasts who don't mind taking a big risk on bleeding edge tech knowing full well something better will be right behind it when more of the kinks have been worked out
 
we already have enthusiast/youtubers getting oculus rift and pretending on cameras, so we as real enthusiasts will be second wave/gen ;)
 
Love these threads. I'm seeing more and more AMD fanboys posting only positive AMD news.

AMD = Best thing since sliced bread.
Nvidia = Panic, run for the hills, you're doomed.

I've got that right, havent I ?
