Thread starter Thuen88 Start date Feb 8, Its jumps around from the high 60 to 90 FPS, average around This causes a lot of micro stuttering and jittering around the stations, so i tried the Motion reprojection to force it to 45FPS. Even here the FPS is not able to maintain a stable FPS, but is jumping from FPS which doesnt make any sense cause with Motion reprojection turn off it never reaches those numbers.

With this turned on it still creates a lot of stuttering, and jittering along with artifacts. What is going on here? Is the Motion reprojection just that horrible with this game or am i doing something wrong here?

Last edited: Feb 8, What about the rest of your system? There are a few factors but it's worth knowing them as well. I run a Ti and an ancient i7 3xxx series processor and I can keep 90fps. Also, do you use the EDprofiler? If not, get that and show us your graphics settings - there are few things like like AA that you can, and should, switch off that may make all the difference. Sorry if you know all of this! Ive turned off AA and ambient occlusion.

What hmd are you using? I think everyone gets dips in stations - but I've disabled motion reproj and so if it dips, I don't notice it. I use both a Rift and a WMR at present. I'm waiting on the Pimax 8k with which I expect to upgrade; but I'll see how it goes. I didnt get any stuttering and jitter with my Rift and my old GTX ti. Anyway my main convern was why the FPS isnt stable at 45 with Motion Rep turned on when turned of im never in the low 40 FPSbut in the high 60s in the worst case scenario?

And thats super rare. There is no point using this feature then. That I can't answer. If Reproj comes on all I get is wavy lines and blurring - which I think is largely PC related for me it's old so I can't use it. There should be more than enough power there unless it's Elite or driver related.

Yes im dissaponted to say the least. Maybe im just to sensitive for this issue. That would take care of this immersion killer.

I am sure youll find something acceptable but you wont get 90fps its impossible.Home Discussions Workshop Market Broadcasts. Change language. Install Steam. Store Page. Global Achievements. Enabling either of these settings causes severe stuttering to the point of unplayability.

This doesn't make any sense at all since the game is certainly capable of maintaining more than 45 FPS and indeed even more than 60 FPS without those settings enabled.

Having the "motionReprojectionIndicatorEnabled" : true setting to show the in-game indicator shows a dark blue box, indicative of a GPU bottleneck, which is as expected because that's the reason for motion reprojection in the first place, to mitigate such a bottleneck. Prior to whichever update is causing this problem the motionvector reprojection seemed to be working correctly and the gameplay was super smooth. Now, unfortunately, it's garbage. There seems to be plenty of GPU headroom so I don't understand why it's not being properly utilized.

Another example is the racing simulator rFactor 2. This again doesn't make much sense since the "auto" setting should not even be invoking the motionvector reprojection because the FPS is naturally over Relevant hardware: ik stock 4.

Despite not having a beast GPU it was previously sufficient for smooth gameplay. I've checked to make sure supersampling didn't get set anywhere, e. I've also rebooted the system and tried closing all other desktop applications to limit resource usage and avoid unintentional conflicts. I concede that a recent Windows system update might also be the culprit but since the issue is specifically with motionReprojectionMode this is as good of a place as any to ask.

Anyone else recently having performance issues after once enjoying great performance? Any suggestions for things to try to fix this? In fact I have to turn it to "auto" or else there is a weird double-image in-game whenever the truck is in motion. Last edited by Pert Boioioing ; 4 Feb, am. Showing 1 - 15 of 82 comments. Yes, terrible performance with it. Yep, the performance went downhill recently, I had to disable reprojection altogether to play Assetto Corsa.

I force the monitor to refresh at 30, or 45 Hz for headset at 60 or 90Hzforce Vsync through the display driver gtxthen set "motionReprojectionMode" : "motionvector" This works ok I can see all kinds of glitching and texture pop-in when the game needs more VRAM. So it has to dump something, then request again, which is when the stuttering starts.

That's just what it 'feels' like Microsoft definitely need to focus more on GPU resource management though. Multiple processes using GPU resources are currently not controlled well at all. The other problem I see is that reprojection needs to be tuned differently for every game engine We need tuning parameters. Both microsoft and valve are at fault here, and assume that 'on' will work for every scenario that needs it.

Maybe they have some crazy AI leaning controller adjusting things on the fly, but I'm betting not. They have tunable variables set to what 'should' work, and lock those for everything.

Last edited by DerekSpeare; at PM. I'm fairly new to WMR. What does Motion Reprojection do? So essentially, it's guessing what the next frame will look like, giving it time to deal with the next real frame. That's the short version. It can leave artifacts but makes the VR experience more smooth. Some love Rift's version of it, and others don't. I will have to try it at home and see what my bottle neck is.

Yep, it's that Originally Posted by DerekSpeare. Holy Crap!!!! Does that ever make a difference. Little bit of shuddering close to the ground but for the viability, who cares.

Both systems are not enough. I prefer the Rift slightly. It has a much better sweet spot but the Lenovo is good and WMR is really cool It's very slightly better than the Rift for SDE. I have not tested the WMR system in a couple of weeks.

It was made to lower the perceived latency of VR.

Blockbench armor

VR before the Oculus DK1 had much higher latency than today- mostly due to software rather than hardware. Timewarp is one of the multiple software techniques Oculus used to get latency low enough to not be noticeable.

Timewarp reprojects an already rendered frame just before sending it to the headset to account for the change in head rotation. That is, it warps the image geometrically in the direction you rotated your head between the time the frame started and finished rendering. Since this takes a fraction of the time that re-rendering would and the frame is sent to the headset immediately after, the perceived latency is lower since the result is closer to what you should be seeing. The concept of Timewarp is used today by all major VR platforms.

Asynchronous Timewarp takes the same concept of geometric warping and uses it to compensate for dropped frames. Diagram from Oculus. It was not available on PC however until the Rift consumer launch in March Rather than being an always-on system like ATW, IR was automatically toggled on and off by the compositor. Interleaved Reprojection actually had some perceptual advantages over asynchronous reprojection as it makes any double image artifacts appear spatially consistently.

Timewarp at current and Reprojection only account for rotational tracking. They do not account for positional head movement, or for the movement of other objects in the scene. ASW is essentially a fast extrapolation algorithm which uses the differences ie. Despite the name, ASW is not always enabled.

It then forces the application to run at half framerate 45FPS and synthetically generates every second frame. Diagram from Oculus Connect 3. Because ASW only has the color information of the frame with no understanding of the depth of objects, there are often noticeable artifacts imperfections in the image.

Asynchronous Spacewarp 2.

Motion reprojection WMR

When announcing the technique, Oculus showed the following scenario as an example of the visual artifacts the 2. Unlike all the other techniques so far however, ASW 2.

The developer has to submit their depth buffer each frame, otherwise it will fall back to ASW 1. Thankfully though both Unity and Unreal Engine, which together power the vast majority of VR apps, now submit depth by default when using their Oculus integrations.

Like ATW today, the PTW update will still be always enabled, so as soon as a frame drops a synthetic one is ready in time.

But just like ASW 2. Instead, when the compositor notices that the framerate has been low for more than a few seconds, one of these modes is enabled. When enabled, the compositor forces the running application to render at half framerate 45 FPS for current headsets. The compositor generates every other frame synthetically, based on analysing the previous frames and incorporating the headset tracking data.Home Discussions Workshop Market Broadcasts.

I use a lenovo Explorer to play to Assetto Corsa, on a standard sim rig. When playing alone in hotlap mode, I reach 90Fps and image is smooth I saw from ranXerox's profile that this drop in FPS is caused by the interleave reprojection, so I'll try disabling this feature From my understanding they are doing the same thing isn't it? Should we activate both or only one? It would be much appreciated to get some help or hints here.

Showing 1 - 5 of 5 comments. Interleave reprojection forces your headset to operate at 45fps when it cannot maintain 90fps. This Feature is old. Async reprojection maintains 90fps as best as possible before failing by filling in frames with recycled frames. I like increasing supersampling this until I see visual jittering and I back off a bit with this feature on.

Review Type.Keep your finger on the pulse of the XR industry with the Daily Roundup, the most important news in one daily email. PC VR headset demand relatively powerful gaming hardware because games need to be rendered at very high resolution, in 3D, and at high framerates.

Doing all of that with very low latency and high consistency can be a challenge even for powerful gaming computers which may occasionally fail to render the next frame by the time the headset needs it, leading to a dropped frame. Without any intervention, a dropped frame will cause the headset will re-display the previous frame, which means the view in the headset looks like the world has momentarily attached itself to the head of the user.

This can be very discomforting in VR, especially if several frames are dropped in a row. Like Oculus with ASW, Valve is implementing an additional layer of performance protection for applications prone to dropping frames, one which can also account for moving objects and characters within the application. It does so by looking at the last two frames, estimating what the next frame should look like, then sending the synthesized frame to the display instead of an entirely new frame.

Motion Smoothing kicks in automatically when SteamVR detects than an application is dropping frames. That means that the user sees smooth 90 FPS motion in the headset, but the application has twice as much time to deliver new frames. Valve says that Motion Smoothing can be used even more aggressively if needed, synthesizing two frames or even three frames for every one real frame delivered by the application.

Reducing or removing the requirement of VR applications to deliver consistent 90 FPS would make it viable for lower end hardware to run VR applications without major performance issues, and for higher-end hardware to run at higher resolutions or with greater graphical effects without suffering major performance issues. Oculus recently introduced ASW 2.

With Motion Smoothing just launched in beta, Vlachos notes that there will be much tuning to come based on user feedback, especially in the next few days, though he expects the feature will remain in beta for several weeks.

SteamVR has improved massively this year. Dynamic SS works very well and brings smooth performance to IL-2 on my Elite Dangerous gets a big boost in visual quality since Valve brought dynamic SS. This new feature news is encouraging. If only Valve could return to their game development days.

Meanwhile star citizen is actually taking shape rather nicely and is open to public scrutiny. But you destroyed this with he star citizen part. But I have followed it and it is taking shape very well. I hated Chris Roberts first game back in the day by the way.

Stalker took 7 years and was a very simple game by comparison. Star Citizen and Elite Dangerous have another 8 to 10 years development to go through. I like Elite… but landing at a base on a planet surface in ED is rudimentary. Meanwhile over at SC you have architecture on an enormous scale. A railway… A city covering an entire planet. SC is all about cinematic realism and there is nothing that comes even close and nothing will come close for a very long time.
