Judder only during play

Hello all,

Apologies if this has been covered elsewhere, and if so, please point me in the right direction.

I'll keep it real short: Elite Dangous VR on Oculus: visuals are great as long as I'm in the Training Mode. However, as soon as I enter the actual game (Solo Play) the juddering begins almost instantly, i.e. when I turn my head either direction the visuals become blurry and juddery to a degree where all I have left is abort the game.

I understand that the actual game play (not training mode) is done using an active internet connection. Althought mine is sufficiently fast, can the judder have something to do with that?

Any help is greatly appreciated.

Thanks,
Chris

Hi Chris,

I don’t know any links I can point you at but it’s a known thing that the VR training scenarios are unrealisticly undemanding on a system.

What’s probably happening is your CPU can’t cope with all the demands of the real game and tell your GPU what to do fast enough at the same time.

You can test this by running task manger and looking at the CPU and GPU performance and your frame rate though you nose gap on your rift. Ctrl+F will show the frame rate Elite is running at on the bottom left corner on your monitor. If you have a green 90FPS your system can cope but if you have a Red 45FPS something can’t cope.

If you disable ASW by pressing Ctrl+numpad1 your system will be more likely to run an FPS between 90 and 45. The component that is almost at 100% use in task manager (if that happens) is the thing holding your system back. If not it’s more complicated.

Your specs will help...

Hello Gortron,

Thanks for your promt reply and suggestions.

I feared that solving this will not be as easy as removing the check-mark next to where it says “Judder” :) However, considering the fact that I had purchased the hardware almost solely to engage in a game which takes me back to a time during which I was playing said application on a C64 I do not need to tell you that this is rather disappointing.

I shall follow your recommendations in the next few days and report back. In the meantime here are a few specs:

⁃ Win 10 Home , Version 1803, 17134.345
⁃ Processor: Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz
⁃ 12,0GB RAM
⁃ System type: 64-bit, x64-based processor
⁃ Video: NVIDIA GeForce GTX 1060 3GB

I hope this suffices for the moment.

Thanks again,
Chris

With your specs turning off ASW to test won’t really achieve anything and will probably just give you a horrible VR experience.

You might have been a bit over ambitious with the graphics settings in which case you will see GPU use at 100% and need to dial things back a bit.

It’s worth checking the Windows gaming settings and making sure all the game DVR settings are set to off.

A few others here have had judder problems recently that were down to drivers and the like so hopefully some of them will have some suggestions too.

Don’t worry about seeing red 45FPS with your specs but anything lower isn’t good.

Hi Gortron,
strangely CTRL+F does nothing on my PC but I have installed a freeware called Fraps which measures the frame rate: it never goes above 45 and while it is steady at that value the picture is fine. Every few minutes it will then fluctuate between 30-45 during which the juddering starts until it returns to 45 and the game is playable for a few minutes.

I take it my video card is outdated/not suitable? Are the software means to increase FPS?

Thanks.

P.S. Everything is selected off in the DVR Gaming settings.

VR is extremely demanding and a 1060 is at the lower end of what is playable in VR (it should still be playable though). The reason your hardware should be ok is because of ASW Read the link and it explains it. 45FPS should be ok but you are going below that (hence the juddering). I'm wondering if what is happening is your Graphics card is running out of VRAM and refreshing and that's the judder you are seeing. My GPU has 11GB of VRAM and ~6GB is normally being used in VR. If your GTX 1060 has 3GB of video ram then that might be the problem. Hopefully someone with a similar system will be able to help... ??

I was playing on 1060 6gb quite happily for a year on an otherwise fairly decent system (i7 7700k, 16gb 3200 ram). I think the 3gb card is pushing it a little though - isn't the 6gb 1060 considered minimum spec for VR?

That said, if it was fundamentally a GPU/resource issue, would you expect to see such a dramatic difference between training and the actual game? Seems odd.

I ran the GTX 970, which has only.5 gb more in ram on a mix of low and medium. There quite a few settings that can be raised to high as the have no impact on performance.

Shadows should be low or off, SS no more than 1 and HMD to one as well. I'll dig around and see if I can find my settings from the GTX 970.
 

dunno

I have great Clarity with my CV1, also butter smooth : 1080Ti and 7700k stock and OCl'd @4.8

In Elite;
HMD = 2
SS = 0.5
SMAA
Shadows off, jet cones min, Blur off, Ambient occlusion Med.
All other settings ultra/Max
Terrain Work slider > max to the Left.

THEN with Oculus Debug tool, which must be opened before Oculus main application and remain open for session;
Set Pixel Per Display Override to 1.9 (max is 2.0)
ASW = Auto

And bingo, perfect clarity smooth as butter. If you want to see FPS and GPU performance in game set Oculus HUD overlay in Oculus debug tool.

Your headset has a 90Hz refresh rate and, ideally, your minimum frame rate should match this.

You are seeing 45fps because you cannot maintain 90 so it has to show the same frame twice. Occasionally, when your setup cannot maintain 45 fps, it drops to 30, because that is one third of 90, so has to show the frame three times.

This is far below optimal and you will need a faster GPU (and possibly CPU) or significantly reduced graphics settings, which others have gone into more detail about.

A lot of people run ASW and have no issues, not everybody has the money to run a top notch system and as long as they understand and accept the limitations and it doesn't cause physical issues then it's fine. I ran a GTX 970 for over a year and I had no major issues... By what you say I should just bite the bullet and upgrade to a RTX 2080ti. That ain't gonna happen.
