PASCAL

[Chivas]

Pascal is the much needed answer for VR DCS. The new single pass multi projection tech will remove the hit VR takes on our frame rates, making it so much easier to maintain 90fps/hz. Along with the much higher performance, users should be able to fly DCS at the highest settings with few problems.

[SkateZilla]

that's an assumption,

 

rendering 2 Individual Viewports will effect frame rate regardless, no amount of marketing will change that.

 

the DCS DX11 Engine Renders Two Viewports, nVidia and their GPU has no Say in that, it does what it's told.

suxx!

i wanted a 1080 on the release day, but i have to be patient to get a aftermarket version that comes overclocked.

 

must have will power

[SkateZilla]

wait for aftermarkets and reviews.

 

Some AIB partners are sayin 2GHz is easy on AIB Cooling solutions.

[Chivas]

It definitely will effect frame rates positively when this new tech can send two different images to the VR displays in ONE pass. Only an exclusive AMD user would view this as a bad thing. I am surprised at the lower price point, which make me think Nvidia is worried about what AMD might have up their sleeve. This is very good for consumers.

 

Hopefully DCS, and Oculus SDK can take advantage of this new tech in the near future. There is always marketing hype, but its NOT ALL marketing hype, otherwise we would still have the performance of the first gpu's.

It will be very interesting to see the VR benchmarks.

980ti owners are probably crying now :D

 

GTX Titan X and GTX 980 Ti, retail for $1000 (£800) and $650 (£550) respectively. In the case of the GTX 1080, Nvidia claims it's twice as fast as the Titan X in certain VR applications and three times as energy efficient—it even says it's faster than dual-SLI 980 setup.

[dot]

Apparently it's 3X faster than GTX 980 in VR due to architectural improvements:

I'm happy with this, might be able to get 980 and 980ti quite cheaply soon :)

 

No one even mentiones poor GTX 970 any more :D

[dot]

PCGamer says it is faster than two 980's in SLI.

 

"In raw performance, then, we're looking at a card that will be at least 30 percent faster than the GTX Titan X"

 

http://www.pcgamer.com/nvidia-gtx-1080/

 

 

While the 1080 is a good card, its a far cry from the misleading nVidia announcement of a 1080 that is 2x faster than a Titan. 200% shrivels to 30% in the cold light of day.

 

Yes, but I'm talking about VR performance...

[dot]

If it works on DX 11 games, which it probably won't. The games need to be DX12 games and coded specially for an nVidia card get to get that kind of performance. Most games won't show that kind of performance.

 

I'm not saying it is not a great card, it is. Just that Nvidia's marketing numbers will be less in the real world as PC Gamer points out. Expect 30-40% performance boost in 1080 over a Titan (which BTW is very good)\. If you are expecting 2x the fps of a Titan from a 1080 you will be disappointed. Maybe it will happen with a ti. I'd wait and see more reviews of real cards.

 

Yeah, this would probably motivate me to move to windows 10, but only if both my force feedback joysticks work fine (MS SideWinder FF2 and Logitech G940 :)

 

I can see the Single pass stereo as one of best features for VR:

 

Single Pass Stereo

VR requires stereo rendering, which requires submitting and tessellating the geometry in the scene twice which is expensive. Simultaneous projection solves this by allowing input to be shared between render targets. The GPU takes the geometry, processes it once, then adds an X-axis offset to provide the correct perspective for other eye. This means the tessellation and vertex shading work is only processed once, reducing the GPU’s geometry workload by half.

Windows 10 won't help you. Read Skatezilla's post on this. You will be disappointed as i was.

Note "certain VR apps" Single Pass Stereo will only work on certain games and DCS is not likely to be one of them.

 

Don't get me wrong, the 1080 is a great card for the money, but temper what nVidia says and you will be more in line with reality for your gaming performance. That's all I'm saying. The ti will be the real monster card. The smart thing is to wait until the reviews are in and the cards are tested in the real world.

 

DCS is a special story..

 

The problem is that current DCS engine is not optimised for VR and I have a feeling that even hypothetical GTX 1080ti would struggle to maintain 90FPS above cities (without timewarp).

How they choose to address this performance bottleneck is up to them, but luckily some people (amd, nvidia) have already made some work on this so hopefully DCS devs will find some time to implement DX12 improvements into their engine...

 

bdw, which GPU do you currently have?

Well it might gain some FPS, but not much. Skat is right coz the big hardl is Dx11 which is single thread and future cards will be efficient on dx12 and Volcan

the point is to move away from single threaded rendering engines as soon as possible.

Nvidia, AMD and Microsoft have done a lot of work on this and now it's up to game devs to implement it.

 

I understand that devs might not want to implement it in the near term (they're probably on a fixed salary) so we need to make more noise :)

Single Pass Stereo is part of VR Works, which is part of GameWorks Rendering Engine, which ED Does not use.

 

Its not gonna happen at all.

 

Unless ED Implements its own version of Axis shift, which Im pretty sure already is in use if you look at the LEFT/RIGHT and 3 screen monitor profiles.

I'm not advocating for GameWorks at all, I'd just like better performance in VR.

At this point I'd be happy with DX11 multi threaded rendering (and hope to hear that devs are testing Vulkan).

[SkateZilla]

I doubt ED is looking into Vulkan.

 

as for VR, the entire thing is WIP, Tweaking will continue for a while as new tricks and stuff are learned.

I wonder if it's possible to add support for the new Simultaneous Multi-Projection independently of any extra baggage, multi monitor bliss. Would a targeting pod camera be considered a viewport (edit: in the SMP sense)?

DCS Uses "Viewports".

 

Left, Right, Center, MFCD, etc etc,
