The improved visual difference between "no supersampling" (1.0x) and "0.65x in-game SS and 1.5 Oculus Debug Tool SS" (still effectively 1.0x)

The improved visual difference between "no supersampling" (1.0x) and "0.65x in-game SS and 1.5 Oculus Debug Tool SS" (still effectively 1.0x)

I took some screenshots of the visual difference between going with no in-game supersampling (1.0x) and setting in-game supersampling to 0.65x with the Oculus Debug Tool supersampling at 1.5x. (That effectively puts it back to 1.0x, since 0.65 is basically 2/3, times 1.5, so 3/3, or 1.0x.) Theoretically, this shouldn't make any difference, since they're both effectively rendering at 1.0x. But there is definitely a difference. Some people were thinking there wasn't really going to be a difference, and it's hard to prove that in an HMD, since "it's better" is pretty subjective. I mean, I think it's better, but how to prove that? I can't, because it's subjective. But, the screenshots do show that you're sending a better, crisper original image to the HMD that uses the pixels more effectively, especially with the text. And sending a better picture to begin with is definitely going to help in the resulting image that shows up in the HMD.

The screenshots are as follows:

1) At 0.65x in-game ss, with no Oculus Debug Tool ss, for reference to see that 0.65x is actually making the quality worse.
2) At 1.0x in-game ss, with no Oculus Debug Tool ss, for reference to see what the standard baseline is.
3) At 0.65x in-game ss, with Oculus Debug Tool ss at 1.5. Compare #2 and #3 side by side and there is a marked difference in quality, particularly in the text rendering. It's much easier to read in the Rift. (And it wasn't even hard to read to begin with!)

Even if it is only achieving the same result, due to the very poor optimization of SS in game, you get a lot better performance using the debug and thus overhead to tweak other settings to improve the image so totally worth it.

Wahey cool! i'd resorted to running it stock at 1xss in game and no debug as i'm on a gtx970, It really struggles to play nice.
i'll try this method as I just need it to be a little sharper than stock, then i'll be happy for a few months... until I get a 1080 or something with some real vr grunt!

Wonder why... Maybe LOD and Mipmap biases do not follow along, when choosing Elite's scale factors, but remain as they were at 1.0, or something...

Its how I have it set on my 980ti, i tried a few different settings and that one looked good so I haven't changed anything since.;)

I'll give this a go tonight. Where do I download the debug tool? or is it already built into the Oculus software somewhere?

You need to download it from the Oculus site. Link

Please show in game graphics with these settings.. the pics with in game set to 0.65 will look noticeably worse than those at 1.0 or higher.

980ti, 1070 or higher users should do 1.5 in game and no change via debug tool to get the best quality for graphics and improved readability for text.

1.0/1.5 is probably a reasonable hack to make text more readable while maintaining graphics quality but 1.5/1.0 will look even better at the cost of higher rendering requirements. This is because only the game engine does the rendering while the debug tool is a simple scaler.

Mboffin,

Are those pics from the monitor or from the Oculus? If they are from the Oculus how did you manage to record/get pics from there? Whenever i try to get pics from the Oculus it just screenshots the monitor view....which as everyone knows is obviously way way sharper and better image.

But i agree with what youre saying re: the oculus SS and the elite SS. I found the Elite ingame SS to be quite poor to be honest..very aliasy and flickering. Whereas using the debug tool provides way more clear image quality with far less artifacts for me. I use 1.0 in game and 1.3 oculus SS with a gtx 980.

This may sound like a silly question, but how do you change the SS in game? I've looked through all the game menus and not seen it anywhere.

In the options>graphics>quality section. It's a dropdown menu.

Edit: Oh wait, do you mean change the in-game SS in game? Or do you mean change the SteamVR SS in game? Because you can change the in-game SS by going into the in-game options and applying your changes. But it doesn't do any good to change the SteamVR SS while in game as the changes wouldn't take effect until you restart SteamVR.

Keep supporting the lame VR products. Maybe in a few yrs it might be worth getting, as long as it's put into a wrap around pair of sunglasses and focus without glasses. Never gonna wear a diving helmet for a frakking game. Spend your money, you go.

Exactly my thoughts and, as far as I know, these pics can only be from the monitor.
And if it were possible to take screenshots with the Oculus, you should compare them ON the Oculus (and not on the monitor we use to read the forum), so this makes the comparison pretty useless.

If you use the ingame screenshot key, you'll get the side-by-side picture that is projected into the headset. I think that would be exactly what we need here, instead of the low res monitor feedback window.

I admit that an ingame side-by-side picture is much better (I didn't know it existed), but even then you should compare them through an Oculus and not on a monitor.

It is the quality of the image sent to the HMD that is on test here; Not the display technology.

I don't launch Ed through Steam but via the FD launcher. So I did mean in game as in Elite's options. I'll have another look in the graphics options but all I get is a load of presets like VR High or Medium and Ultra etc and Custom. I use Ultra at the moment and I can't see any options to change the SS. If I try Custom it doesn't seem to give me any more options either.

When the options were organised into collapsible sections, settings became much more manageable, but as you have noticed, it doesn't work quite the same in the graphics options, because the lines to click are not only section headers, but settings in their own rights, which when clicked pop up a menu where you can select a set of presets for every option in the sections they comprise.

To deal with this; At the same time a secondary selection action was added, for expanding and collapsing tree structures - you can think of it as a mouse right-click, if you like.

...so to get to the graphics quality options; Either assign a button (maybe your secondary fire button) to this function, in the key bindings, and use that instead of your usual button, on the same line that otherwise opens the presets selector; Or reach for a mouse and click not the option keyword, but the little box with the plus sign in it, to its left.
