Try This Judder Fix For Windows

[McFaulTech]

I believe I have found the cause of judder finally. I have tested tons of demos today that previously juddered for me before. If you could suggest one for me to try then I'd like to go for it, just make sure it has a direct to rift exe included and is built for the sdk4.4

EDIT: when I started this I was under the impression that the material needed to be updated to the sdk4.4 in order to work, however after testing several I find that Some of the best experiences I've had in VR while running the 4.4 are not material that has been updated to the 4.4 - live and learn!

I believe the key is to disable Aero Snap, but leave aero running, even for windows 8. I haven't done any testing with Windows 8 or 10 yet, just 7...however Windows 8 should be the same even though most people think that Aero is absent from Windows 8. There are still bits of Aero in Windows 8 as you can read here: http://www.howtogeek.com/128819/aero-is ... still-use/

Disabling Aero Snap will also disable your ability to use the shift+win+arrow key combo- which is why this only works with Direct 2 Rift at the moment. Another side effect is that you loose that stupid jiggle feature, which could also be the cause of judder.

All this can be done by simply doing this:
1- click search in your start menu and type mouse but dont hit enter, look to the result and click "Change how your mouse works", then check the box that says "Prevent Windows from automatically being arranged when moved to the edge of the screen".

2. Put the oculus config into direct to rift mode

3. Start one of your direct to rift demo exe's

*note*- sightlines the chair is a power hog as it loads new textures everytime you move your head. For that one you need to hit F to view your framerate and once you see it hit 75 you should see the judder vanish. Actually the studdering during the loading of textures looks a little different then judder. I think it's just my slow ass hard drive (WD Green) causing that...but once the birds start flying around then everything should be smooth.

To disable snap in windows 8 just do this: http://www.forumswindows8.com/general-d ... p-2394.htm

Most of these work mirrored automatically, a few don't. When mirrored I have checked fps and the rift is running 75hz while the main display is running 60hz....the way it should be 🙂

UPDATE: Testing Steam Games today in Direct to Rift, I don't have too many but I'll do what I can 🙂 method is by seeking direct to rift exe's in steams common folder. Then a few without d2r exe's but still in direct mode.

I haven't gotten to the steam stuff yet 🙂 testing demos all night and adding them to the list in the first post. So far I havent been able to find anything with actual judder. A few give me low fps and a skip now and then but none of the vertical bounce that you get with judder.

OK, I am going to test this with Pneuma, which is a judderfest. :twisted:

Pneuma is a steam game which means no Direct to Rift....read the first post. Should work if you can get it to open o the rift instead of your main monitor. But with aero snap disabled you can't use Shift+windows key+ arrow to move the image over to the rift. Windowed mode will most certainly cause problems with vsync.

but if you intend to try and get steam games working then don't forget to disable the steam overlay. I'd give it a go but no way am I paying $20 for 45 minutes worth of simple puzzles that may or may not run well :roll: The reviews are good, but too many people saying it's too easy and too short.

Actually it does run direct to rift through Steam. I haven't had any luck getting it to display on the rift at all in extended mode.
Anyway, things are a bit odd here - the 1st couple levels were judder free, then I got judder for awhile, but now I just get motion blur. The fps has dropped so low I no longer have low persistence and can't test your theory on this game. I'll see if disabling steam overlay helps.

yeah steams overlay messes things up, but some of these that don't shutdown properly need a restart of the system to clear things out....to be expected with Alphas i think 🙂

right, i tested this on 3 direct to rift demos that were causing me bad judder issues

helix
pod racing
titans of space

i can confirm all are now judder free, smooth as silk

one note of caution, i havnt tried any of these demos since i upgraded my 7970 to a 970

disabling aero snap has also given me a better image quality on both rift and desktop, dont know why though ha

[McFaulTech]

what about your elite dangerous experience now? 🙂 judder is the only reason I was waiting to buy that one :roll:

and btw: I didn't make sli profiles for my crossfire so in my testing I am technically using only one 7970 g.e. watercooled at stock speeds and only have fps issues on sightlines the chair and maybe one other that I cant remember 😕

[Gimmel]

I can confirm that Dreadhalls was being particularly stubborn when most others were working, and with this fix it now works at full speed!
Good work!

Hmm, I just tried this in Beneath 2.2 and Technolust: A Way Out and it didn't seem to make any difference to me. (Win7 64bit, i5 2500K, GTX 970)

It may just be that it fixes a type of judder I was never experiencing in the first place? The "judder" I get in those two demos is simply low framerates (unnaturally low in Beneath's case, as I get <50fps in Direct mode but ~200FPS in Extended) -- unlike the true Direct mode judder I'd experienced with DirectX 9 and earlier runtimes, which was some sort of prediction glitch unrelated to the frame rate.

Yeah, Technolust demo, according to their site, is for DK1 only 🙂 I see you can buy into a newer beta though, for the dk2. I like the concept so I'm gonna have to get in on that one. Looking at their imagery I'm gonna guess it's low fps. Looks pretty demanding...awesome too. In the case of beneath 2.2 though...you get 200fps in extended??? not me lol. I get smooth but low fps but there is some sort of persistence problem. I get that with a few but it's more of a ghosting smear then a judder? Judder is more of a tiny up and down twitch while stuttering as you move your head...I have had a few that performed like that but mainly because of low fps. There is a helicopter one that has insanely low fps around 3fps...even that one doesnt judder but does do some oddball super low fps stuff. That one starts you off in super shiney high res water textures though...beneath is pretty shiny too. I think those are just individual game glitches the result of being alpha builds 😕
Have you tried any others??? Your system should get good fps in most others. Don't forget to deisable hyperthreading, hyperthreading causes stutter in many games without the rift 🙂

elite dangerous

the best way to keep it judder free is to run at 60hz, but you have to trick the game into allowing the option to change hz

that said, ED was always very good/judder free on my single 7970, i only upgraded because of judder in certain RES which turned out to be game engine related and not GPU restricted as i have the same fps drops in the same places regardless of GPU
