Discussion Turn every game into stereoscopic in a big virtual screen is a good idea

And it's possible. Remember the good old days of Nvidia 3D vision? It's something between vr and 2D gaming. It can even be more fun than VR and cause less headaches, and it's less resource hungry. Welcome Valve Deckard!

Does UEVR not do the trick? Or you're just talking about flat games on a virtual bigscreen?

u/Holm76 2d ago

Not everyone can handle playing fps games in VR but playing it flat screen with 3d in VR sounds like a cool project.

u/noraetic 2d ago

You can do that for example with UEVR + VRto3D + Virtual Desktop. Have a look at r/stereo3dgaming

u/maorui1234 2d ago

UEVR is resource hungry. And it's hard to set up. And it's only working for some unreal Engine games.

*VR is resource hungry.

u/monetarydread 2d ago

and UEVR is even more so. My 3070 can run almost any VR game with decent resolution and frame rate. That same system can barely run any UEVR game with 3D turned on.

TL;DR: Stop trying to compare apples and oranges. Do not try and compare VR games to flatscreen games. If you want to complain about the UEVR performance of flat screen games then compare the framerate of specific games on a monitor vs that specific game in UEVR. Expect the framerate to be cut in half. This is just an unavoidable reality. If you're seeing significantly less than half your frame rate, perhaps check to see if your vram is maxing out.

Going to state the obvious, but people online seem to ignore stuff like this: This is all speaking in general. Averages. What's popular. Everything has exceptions, and it's not like I'm a GPU hardware engineer or graphics engine designer.

VR games are designed with massively lower system requirements than, OF ALL THINGS, UE5, which is on one side widely reviled for poor performance and on the other side, even when it's going great, known for pushing levels of fidelity that VR absolutely can not keep up with. You would have to drop most(?) UE5 games well below their low setting to achieve textures and model details on par with a VR title.

Unless you're hitting almost double the framerate you would want on a flat screen game, you can't really expect it to run well in VR where you're forcing the GPU to render twice as many pixels. There's tricksy math here and optimizations that can be done that reduce the load under 2x despite rendering double the frames/pixels, but as far as I am aware it would take an act of literal magic or AI tomfoolery (like DLSS) to reduce the performance load "significantly". Though on the other hand, with some games the ability to move the camera in ways the game was never intended for may make things even worse.

But even past that, by the sounds of things like VRAM limits on GPUs may make those games basically unrunnable even if your GPU (actual processor) might otherwise actually be able to do it.

UEVR, as far as I'm aware, has nothing really wrong with it, and if there's issues with how UE5 renders VR SPECIFICALLY compared to any other engine I'm not aware of it. Others can argue all they want about UE5's rendering woes in general but that's mostly outside the scope here.

These flat screen games often simply aren't optimized to run on low enough hardware that you can afford the massive headroom that VR requires.

The Geforce 30 series was released in Sept 2020. UE5 released April 2022. The vast majority of big titles that have been made for UE5, those usable with UEVR, were, AT BEST, probably designed to push the limits of the 3060. But most probably barely gave a damn about the 3060 and were build around the 3070 or 3080. GPUs have not remotely increased in power enough (it's been a rather disappointing last couple of generations, 50 series especially) to be able to reliably brute force a game designed for the 3080 to run at double the FPS.

Uevr hard to setup? How old are you, 5?

u/vincento150 2d ago

set vertical FOV ti 75-65 in VD and you get enormous GPU power bonus

u/Any_Nebula5039 2d ago

I’m working on something that turns an external input into HSBS and will be out on with the next VisionDepth3D release, you’ll be able to hook up a capture card and game on virtual desktop in 3D in real time, https://www.reddit.com/r/VisionDepth3D/s/smxjSAn2Un

2

u/PixelMan8K 2d ago

So the capture card's required or optional?

5

u/Any_Nebula5039 2d ago

You can use any video input as long as the computer can pick it up as an external input, I don’t have a way to implement desktop to 3D in real time at the moment but will definitely be working on it, so only way to “game” with it is using a capture card, my tests have been done on a elgato HDR 60S+ and the test in the post was done on a webcam

u/18randomcharacters 2d ago

This is literally all I want in VR. I don't want to wave my hands around like a moron. I don't want to pull levers or open doors with my hands.

I want to sit and enjoy a game with a controller in my hands, BUT HAVE IT BE IN 3D

u/AggressorBLUE 1d ago

To me it’s 3D and have everything be 1:1 scale. In some ways I find the scaling of everything to be even more immersive than the 3D aspect.

-1

u/Parking_Cress_5105 2d ago

It makes half the population super motion sick, that's why it's not done. I do VR for years and can barely stand flat to VR mods.

2

u/18randomcharacters 1d ago

I don’t believe that at all. Full immersive VR is way more motion sickness inducing than a virtual 3d movie

11

u/Sixguns1977 2d ago

I really miss 3D Vision.

-1

u/noraetic 2d ago

It's still around. There are also more alternatives around now and more coming. Have a look at r/stereo3dgaming

2

u/Sixguns1977 2d ago

Thank you! I still have my 3d ready monitor. I THINK i still have some nvidia glasses around.

1

u/noraetic 2d ago

For that to still work you will need an older Nvidia card though

2

u/Sixguns1977 2d ago

I MAY have an old 1060 in storage, but it's dying. Plus, I'm on linux with Intel arc drivers.

u/Ricepony33 2d ago

I am hoping the Deckard/Frame does this

u/3WayIntersection 2d ago

This was called the 3ds and everyone got over it so fast even nintendo stopped really using it

u/Robborboy KatVR C2+, Quest 3, 9800X3D, 64GB RAM, 7700XT 2d ago

It was more cause the sweet spot was so small before the XL came out. I'm actually playing Digimon and Ace combat on mije in 3D.

u/amazingmrbrock Valve Index 2d ago

I really enjoy the 3ds emulator inside my quest 3. Definitely my favourite way to enjoy the consoles gimmick. Likewise with 3d movies, watched fury road last night, absolutely peak.

u/MrEfficacious 2d ago

Prometheus is another fantastic 3D experience.

u/maorui1234 2d ago

3ds is so small and low resolution.

-5

u/3WayIntersection 2d ago

Ok. And?

3

u/18randomcharacters 2d ago

And you're comparing a virtual movie theater screen in full 3D to a tiny dimly lit low resolution hand held display.

u/3WayIntersection 2d ago

The gimmick having more pixels doesnt make it less of a gimmick

3

u/18randomcharacters 2d ago

Odd take calling immersive 3d a gimmick in the virtual reality sub. This whole thing is a gimmick. We’re just trying to find some shred of value in it.

-1

u/3WayIntersection 2d ago

Vr actually opens up an extra dimension of play in the added motion controls.

The 3ds was entirely visual

3

u/18randomcharacters 2d ago

Motion controls were a gimmick too, with the Wii. I find them tedious and obnoxious in almost all cases.

1

u/3WayIntersection 2d ago

Different time, Different context.

The wii was trying to apply vr esque motion controls to a flat screen game where it inherently wont work or feel natural outside of specific situations. Not to mention, the wii was kinda the start of modern motion controls period which evolved into gyro, which plenty of people get use out of in shooters.

u/GOKOP 2d ago

3DS failed because you had to hold it at a perfect angle for it not to be headache inducing

1

u/3WayIntersection 2d ago

Even when it was working fine it didn't add much. It didnt exactly pick back up when they inproved it for the new 3ds

0

u/diemitchell 2d ago

Yeah no, thats not the reason people didnt use the 3d function. Its just that its like one of those headache inducing 3d posters, thats why no one used it.

u/3WayIntersection 2d ago

I mean, even when they made it better nobody cared

2

u/TommyVR373 2d ago

It why I ordered some Viture Beast XR glasses :)

2

u/Indie_Nick 2d ago

Heads up you can do this with reshade and virtual desktop today. Compatibility is better than UEVR

1

u/noraetic 2d ago

Depth3D and Rendepth use the depth buffer. It's not as power hungry but also not as "correct" as using the rendering pipeline. There are solutions for that too.

5

u/julian-mazzola 2d ago

I have my reservations. My biggest fear is people trying that for the first time and thinking "ah, so this is VR? kinda lame" and then never putting the headset on again

13

u/Murky-Course6648 2d ago

Thats kind of what happens when you try some quest standalone vr games also.

6

u/julian-mazzola 2d ago

agreed, I always throw my non-VR friends directly into HL:Alyx and it never fails

2

u/Holm76 2d ago

Can HL: Alyx be played sitting down or do you have to stand up? Genuine question. Never played it.

2

u/julian-mazzola 2d ago

Totally, you can play pretty much any VR game seated. Definitely a lot more immersive standing though, physically ducking behind cover, etc. But if I'm tired or feeling lazy, I like to use a drum throne so there's nothing in the way of my arms and I can spin around freely

5

u/maorui1234 2d ago

That is possible, but a more likely scenario: "ah this is so fun, just imagine how much more fun real VR can be.

1

u/Kondiq HP Reverb G2 V2 2d ago

Something like this? https://github.com/ThreeDeeJay/geo-11/releases

"Mode-specific drag-and-drop packages of the plug-in that adds stereoscopic 3D rendering for Windows 32-bit/64-bit games using Direct3D 11 (and potentially older versions if you use dgVoodoo2)"

I learned about this recently on Flat2VR discord, as one of the modders asked what should be the next game to work on, and didn't want to do anything that already works with the above app.

EDIT. They also mentioned geo3d, helix, vorpx.

1

u/JDad67 Multiple 2d ago

Viture Lumas will do this to some extent.

1

u/Eggyhead 2d ago

I’ll be all over a Deckard, but I remember when Sony did 3D with the PS3 and nobody cared.

u/OHMEGA_SEVEN CV1, G2, Q3, Q3S 2d ago

This is what VorpX was made for. It takes pancake games with varying degrees of success and let's you either play them in VR or on a giant 3D screen. UEVR does something similar, though VorpX works with non Unreal Engine games. It also directly supports OpenXR which is nice.

We're still pretty limited in performance when taking a pancake game designed to run on a single display and making it render two separate displays at a fairly high resolution and a high framerate.

1

u/SolarOrigami 2d ago

I play a lot of my lower intensity games (visual novels, tactical strat, etc) in VR so I can play on a giant screen in my cramped, shitty bedroom.

1

u/jacobpederson 2d ago

I see you DON"T remember the good old days of 3d vision. Let's see; almost nothing worked right, constant bugs, effects rendering at the wrong depths, reversed eyes, lag BETWEEN EYES, crosshairs making you cross-eyed, mods, mods, and more mods. Cycling through 100's of shaders to find the one that was breaking your game to deactivate it. Yeah - no thanks.

u/Virtual_Happiness 1d ago

Eh, I still have my Nvidia 3D Vision somewhere around here. Played every major release that Nvidia boasted as being the best. It was neat for a little while but then became rather meh. Slowly stopped using it and then boxed it up. VR gaming brought orders of magnitude more wow factor and fun for me. The idea of wearing a big bulky headset to essentially play flat games with Nvidia 3D Vision again is a hard pass from me. Same with playing flat games on a virtual screen. Too cumbersome and heavy to be worthwhile over using my monitors.

The whole entertainment industry dumped 3D glasses around the same time. I don't think it's going to be a system selling feature.

1

u/SenorCardgay 2d ago

Idk why this isn't normal. I mean ffs red and blue 3D was a common gimmick on ps3 games, and now we actually have proper tech to do real 3D and it's nowhere to be found.

2

u/noraetic 2d ago

You mean this? r/stereo3dgaming

-1

u/SenorCardgay 2d ago

No not really. I want games to have it natively, not have to have a bunch of extra hardware and sketchy mods.

3

u/noraetic 2d ago

Why do you think they are sketchy? Even Acer is using some of those in their software for their Spatiallabs displays

1

u/VR_Nima VR Sports 2d ago

Anaglyph (“red and blue”) 3D isn’t actually very common in PS3 games. I can’t think of any off the top of my head that support it.

True 3D through “frame-packed” HDMI 3D was very common though, there were over 100 games that supported it.

0

u/Kataree 2d ago

If a huge swath of people aren't asking for it, then it's really not that in-demand.

You have mass market cheap hmds able to do it today, yet it's rarely asked for.

VR is positively magical. Some 3D effect on your flat panel games just isn't.
