OCULUS RIFT DK2 2560x1440 downscaleing SO Amazing

Hey pll for those that didt know you can downscale from 2560x1440 to the dk2 1980x1080 resolution wich gives you twice as much pixels , but you need a really good rig(pc/gpu)

Whats really so good about it is the distance stuff , like in hypercrusise you can read the far stuff / numbers twice as good. Also in Stations it looks so much clearer just AMAZING and stuff far away looks so much better.

BUT i got a GTX 780ti overclocked before with everything on high and antialing maxed out it gpu was using 70% NOW with downsaling from 2560x1440 to 1920x1080 its allways on 95-99% but i still dont get no judder only a very little in some situations.

Rift is so Amazing even without downscaling could never change back to monitor again , i even gota laugh about the ppl with 3 monitor setup hehehe not comparable anymore.

Heres a HOW TO:

Just set a custom resolution in Nvidia setting under rift 2560x1440 then ingame you can select under rift 2560x1440 and make sure in nvid option to put on 2x ssaa

and then watch you grafikcard go to the limit hehehe perhaps with 2 gtx780ti you could downscale from 4k but i only got one

ENJOY and ppl GET a DK2 its so mindblowing

I'm very sceptical when it comes to downscaling, but I'll try once beta 2 added SLI support (only on GTX 680s here, and a single card couldn't handle it).

Downscaling does work. There is a noticeable improvement downscaling from 1920x1200 to 1280x800 on the DK1.

But personally I don't find it worth the frame rate hit. If you have the hardware to push that resolution though without a frame rate drop - go for it! :)

I read about this somewhere else too. Pretty cool! Also it gives you an idea of the config requirements for when the CV1 gets released, as it seems it might be in 1440p.

What I'm really interested in knowing is how well ED runs in that resolution with the new GTX 970, and with two GTX 970 in SLI... As Nvidia seems to have optimized their new cards for VR, and this card is the one I'm looking at for my new PC when CV1 hits the shelves.

Some info on how the DK2 runs on the GTX 980, might give you some idea of what to expect:

Just tried this
On low settings docked at freeport I was getting between 60 and 65 FPS.

Running at 1440p via Dynamic Super resolution in nvidia control panel, 1440p in E: D settings.

Difference in image quality was better but not massively so, would prefer to play it this way if I could maintain a constant 75fps with it.

This was on an 980 overclocked to 1355Mhz base, 1444Mhz boost.

Crossing fingers that Beta 2 sees a decent performance boost.

An image that is 1920x1080 has 2073600 pixels.
An image of 2560x1440 has 3686400 pixels.

The large image contains more information. Basically the computer draws in a lot more details.

The smaller image has less information and therefore less details.

Essentially supersampling works because the 1080p image doesn't have the extra details to being with - whereas the 1440p image does have the extra details. So when the image gets downscaled it basically has more to work with.

It's the same principle as taking a small photo of 4 mega pixels on a cheap camera, or alternatively taking a 20 mega pixel photo on a DSLR camera and then downscaling it to 4mp. There is way more information in the 20 mega pixel image - so it is always going to look a lot better when shrunk down.

VR is such a resource hog! :(

Makes me wonder if a GTX 980 will even be enough for the CV1 Rift. That said we still have very little optimized VR games to compare against to really be sure of anything.

There are lens distortion shaders applied to the image after rendering so we lose some pixel information because (rendered) pixels are larger in the center of the warped image (than in the display). Added bonus is a slight antialising effect that we get with supersampling.

From what I'm reading, if the CV1 is 1440, which it should be, then to get acceptable performance you'll probably need either 2x 980's OR 1x of whatever the latest wondercard is at release.

Of course lower specced rigs will be able to run, just not at the cutting edge, but then that's been the case for the last 25 years so why should VR be any different..:D

Personally I'm waiting on two fronts; for the release rift, then and only then will I get a new rig to suit.
Don't get me wrong, every day when I read about people's good experiences with the DK2, I'm tempted to splash the cash, but I know if I wait that first experience will be all the better.

Look on it as waiting until you're married to crack your virginity... ;)

Or for those that may not live to see the CV1, get the DK2 now :D

You should have a try of someone else's before you commit. You might find that the experience makes you feel sick.

Make sure you keep your helmet well cleaned. Don't be put off by the thought of how ridiculous you look when you're enjoying it.

And remember it's going to cost you a lot of money.
