1/ Oculus quality at full in game SS x1.0

2/ Oculus quality at zero and in game SS x 2.0

In 1.3.0.3 and 1.3.0.4 i had almost exactly the same fps impact on both setups.

In 1.3.0.5 i get a performance hit of about 8 - 10 fps if i choose 2/

IMO that prove my theory. Before 1.3.5 Oculus Slider quality was computed before SS, and they swapped both managements.

The fact you had nearly same fps for 1 and 2 mean to me than both settings are exclusive. Slider Oculus quality at 0 probably mean Under Sampling 0.5 ( OculusPixel=0.5) and then you SS x2 and retrieve your full picture. So you have the same image quality and computed size than Oculus Slider full (OculusPixel=1.0) and no SS (x1). The max resolution computed is E.g. 1920x1080

If they revert both routine, they first compute SSx2 for point 2 so the computed picture is bigger x2 (E.g. 1920x1080=>3840x2160) and then the Oculus Slider at 0 say: divide all by 2, and you retrieve your original resolution. Time lost (8 to 10 fps) is due to the step computing the bigger resolution first (3840x2160).

In my opinion you shouldn't lower the Oculus Quality Slider if you set some SS > 1x. Ideally this should all be in one slider (edit: only for Oculus owner) from 0.5 to 4.x (from undersampling to Supersampling). Could be wrong but sound logical to me.

Judder gone, I don't know what happened really but I completely resetted the Elitedangerous32.exe profile in Nvidia 3D settings and everything is back to normal and smooth, I'm back at running the game in 4K Nvidia SS, no AA, everything on HIGH, Oculus slider to 0%.

Reason for 4K at Oculus quality 0% was what I read in some optimization thread in this forum. I could not have shadows on high without judder without this approach before. Haven't retested lately though.

I guess that the game renders out in all 4K pixels, loosing some performance maybe, and that the Oculus distortion when running at 0% get very quick gaining a little more than you loose and that's why 4K SS - 0% Slider get a little faster than 2K No SS - 100% Slider with a card like GTX 980. Just a guess thou.

Runs perfectly... until I turn my head. Judder? or something else?

To start with I should make one thing clear, I had this game running very nicely through my rift just 3 days ago, since when I have reinstalled windows and set everything up again... and something has changed. So not my hardware.

Also the problem is identical on 100% maxed out settings and 100% minimum settings (every single graphics option available set to min/off) - exactly the same level of blur/stutter. So again, not the hadware.

All other DK2 demos work fine.

Game runs very, very smoothly at max settings across the board. Positional tracking is completely smooth. But when I turn my head, even very slowly I get very bad, twitchy double vision. On top of this the rotational tracking will randomly add an extra little twitch in now and again as if it has lost signal for a split second.

Running in extended mode

Resolution is set to 1920x1080, refresh 75hz - for some reason though, frame rate limiter can only be set up to 60hz (so I leave it off)

PC specs
GTX 680
AMD 6200 3.8ghz (6 cores)
8gb
win 7 64


Tried so far..

Removing my other monitor (which only does 1400x920 60hz) completely. - no change
Setting adaptive vsync in nvidia panel - no effect
Turning settings to low - no effect
Changing OR SDK to various versions - no effect
Running direct - just as bad, but also locked to monitor res and refresh!


Any tips? A few days ago I sat in the rings of saturn going "ooooooohhh" at the asteroids. Now the same asteroids have double vision and make me feel ill!

Anyone else getting judder since new launcher?

I never would have questioned it could be the launcher until Beavis said he was getting it since the launcher too. But the frame rate is much worse now, especially around stars. When I face away from them it's kinda better but it's just unplayable really.

Just checking it's not me.

I also put in a new powered PCIe card wondering if it's to do with that.

EDIT: Well I just unplugged that device, and made no difference. I'm going to keep fiddling. I'm hoping on hope it's something to do with my system. Anyone replying saying they are fine will greatly reassure me

I've noticed a bit of judder recently, in SC with head tracking. If I pan left to right a get a single "Judd" at about 1 second intervals.
Still narrowing it down, it's not game breaking by any stretch, just a very minor annoyance at the moment.

But, not sure if it's been since the launcher update or one of the last patches.

Apart from that I'm running pretty sweet.

Don't worry guys, I tracked the problem down to one of the power rails not being connected to my GPU. All good :)

FIXED IT!

Wiped my computer and reinstalled windows again. Fresh install of ED and OR. No more judder/double vision.... no idea what was causing it.

100% Judder free, MAX SETTINGS, on a gtx 680

Last post got merged/buried, but this is too important not to be seen.

I had bad judder and or double vision depending on settings.

Fresh install of windows 7, Nvidia drivers, ED and OR (5.1, not 6)

Butter smooth, zero judder or double vision, 100% maxed out settings (1.5 supersampling)

ON A GTX 680!!!

If you can back-up your stuff, give it a try.

Nice one. How did it perform in Stations and Asteroid fields? Getting a new card tomorrow and am thinking about doing a clean install of Windows 7 tonight, in prep for it

I'm getting pretty good performance with my 670's in SLi.. for the first time ever i can dogfight in a RES without judder..prolly gonna do the windows reinstall though

Sadly, this didnt last long. It runs perfectly on a fresh install it seems but after a week of general game installing, windows updates etc I now have to turn some settings down. Not sure what the cause is exactly but just goes to show that something, somewhere is not very well optimised!

windows 10 should perform a lot better since Oculus has been working with the MS dev team :) I sold my DK2 so I could get 980ti hybrid's sli for the CV1 release :p Xmas comes twice this year :D

Judder/Stutter back with 1.3.07

Hi, I don't know if everyone is getting this. But before 1.3.07 was installed, my VR experience was awesome on my low end computer (Radian HD7800 series graphics card). Everything was clean and looked nice, even though I have everything set on low. the galaxy map loaded quickly, the ship interface was smooth and just a very enjoyable experience.

I know about the up roar from others about the graphics, and that is why they went back to the other build. But my Judder/stutter is shocking, its even worse for me now then it was before the 1.3 release. yeah I know I need to upgrade my graphics card (waiting for EVGA 980ti Classified to be released). But I would like to see if Frontier would offer the low end build as well and you can enable or disable in the graphics which settings you want (I would like the choice). Considering that at the end of the year HMD's will be available for everyone and some people may not have the money to upgrade there computer as well straight away.

Does ED "prepare shaders" on each time on startup? You can re-enable it in %app file it does seem it was disabled for AMD cards! This is one source of the super cruise judder.
