Nvidia starts to support DLSS in VR

[speed-of-heat]

Whilst I don’t think this a magic bullet, and while DCS is not supported at present, I think this would be a great boon to VR players if supported.

[RealDCSpilot]

I think it will have a huge impact. I'm really curious to test the NMS VR DLSS release (which should come out soon).

[C3PO]

Would love to have this working in VR in DCS.

[speed-of-heat]

yep  for that to happen it needs ED to submit there code to NVIDIA so that they can run an ML model against it... but it would be so useful!

[Turbohamster]

Gives a decent boost in supported VR games from what I've read

Any improvements are welcome & I guess it would be fairly minimal work on ED's part?

Just wonder if DCS is too niche?

Pretty please ED & Nvidia

@BIGNEWY this could really make quite a difference...

Isn't DLSS only related to Ray Tracing? At least that's my understanding of the technology, it's supposed to make ray tracing "palatable" by supersampling ray-tracing from a lower resolution. Please correct me if Im wrong about this.

I think that DLSS (or FSR) is the magic bullet that VR really needs as HMD FOV and resolution climbs (and we need that they climb)

It uses the RT cores on RTX cards, apart from that has nothing to do with raytracing, it´s a new super sampling technique

Well then it indeed would be a great addition to DCS World, if there is even a remote possibility of it being included in a major engine update the devs should really be looking at this tech. Possibly with Vulkan support?

[Hoirtel]

Rebar isn't supported in DCS but some clever people worked out how to enable it and it makes a nice difference in VR. Maybe the same for this.... #wishfulthinking

[speed-of-heat]

The difference here, is that rebar is just a setting, DLSS requires a machine learning model to be run against the game in order for the optimisation to actually work…

Nah, it´s not even close, without ReBar your CPU can access to only 256MB of VRAM already, with ReBar the CPU can access to all VRAM so in some scenaries, without even optimize to it, there can be a slight enhance.

On the other hand for DLSS ED needs to work with nVidia, as nVidia has to run some game code over his machine learning systems and, once done, the nVidia driver must has support for it as far i remember so i think it´s impossible if ED don´t make it happen

[speed-of-heat]

correct

It's not going to happen.

 

If AMD's FidelityFX Super Resolution gets cross platform support and rolled up into Vulkan, then MAYBE we'll see an implementation for DCS.

Why not?

ED has stated multiple times that they're not going to integrate proprietary solutions. DLSS is one of them.

[speed-of-heat]

its fundamentally nothing to do with Vulkan or Directx implementation, it is completely separate, though I agree ED have said they are not interested or dont have the resources to support proprietary solutions.

[Supmua]

68% increase in framerate in No Man’s Sky with DLSS which is substantial, without an extra cost to NVIDIA GPU owners.  On the other hand, I spent a fortune on my RTX card  just to get 20-25% performance increase.  Machine learning, AI, or whatever you would call it is an important game changer tech that shouldn’t be ignored.  The problem with implementing this in DCS is that it will completely alienate AMD GPU owners, unless there is some sort of cross platform solution.

It feels like a no-brainer to me.

[Icebeat]

By popular demand, this could be huge for VR

As far as i remember, this was the case when DLSS 1.0 was introduced with 20XX cards. DLSS 2.1 doesn't need that anymore, developers can do it on their own.

RTX cards have 3 different core types on the chip, rasterizer (for regular 3D rendering), raytracing and tensor cores (for AI operations). DLSS will make use of the tensor cores only, the combination of rasterizer and tensor cores will bring the performance boost. AMD's FidelityFX won't be that efficient, AMD cards have no special separate cores and their super sampling tech will take ressources from rasterizer performance.

 I haven’t stated that i expect a similar performance of FSR to DLSS but the thing is DLSS is tied to nVidia, FSR uses DirectML and it’s not tied to a one brand, have you seen any proprietary technology on DCS? Yes, just that

That all sounds awesome but man the crashing issue is so terrible  right now ... this evening is the worst I have seen it 5-6 crashes in a roll. Played for hours last night with 1 crash. I'm excited about this but first things first .... the game needs fixing first. Sorry but I totally frustrated right now. 

[RealDCSpilot]

@5ephir0th My post was about that DLSS is not using RT cores, they are purely for raytracing tasks. It uses tensor cores, which also work with WinML and DirectML by the way... So Nvidia and AMD could surely benefit from FSR, but Nvidia will get the boost on top while AMD has to sacrifice some rasterizer performance.

I’ve not had a crash for a week in VR (crashed all the time for me when I first got my VR unit). I use release WMR and latest SteamVR beta. Make sure I’m plugged into an add-on PCI-e 3.0 slot using the enclosed adapter that comes with the G2. Also updaded my X570 board to latest Asus BIOS (I know you’re running an intel board), set the PCI-e slot to Gen 3 in BIOS and run REBAR. Been very stable in MP servers for me.
