It’s a SteamVR system report, not Vive. 

 

Yeah just found it, thanks.

Could you please share your result?

 

I found this interesting Reddit thread discussing about reprojection:

I tried find information about the performance drops metrics, but no luck.

I would also note I solved the per application profile for DCS not working for me as it should.

Apparently it was not pointing to the correct executable, I manually added it and pointed it to DCS.exe in the Bin folder and it now works properly.

I can now changed the resolution for DCS properly without having to mess with the Global resolution to get it where I want it.

Very similar to mine. Not sure this report tells us anything useful.

You both must have something similar in your system configuration, which differs from mine.

 

I want to test again seeing the fpsVR statistics during the flight, maybe I see something related to SteamVR.

I tried to explain the ghosting with fpsVR but it has been quite confusing. I just see the FPS at 45, but I was not able to identify the reprojection ratio in the overlay.

I have discovered that the communication between Vive Console - SteamVR - fpsVR has some bugs, and it cannot display frame drops and reprojection, so it is not possible right now to get that information.

 

I think that my last option is to start a new windows clean installation, and see what happens.

[imacken]

Pretty sure that’s not a bug. I guess it’s because fpsVR takes its info from SteamVR’s Motion Smoothing/Reprojection which the VP2 doesn’t use.

Yes, something like that, the fpsVR developer has published some posts in steam support pages.

I'm installing everything from the scratch, but just one question, did you install vive software from the executable downloaded from the vive webpage?

[imacken]

I did. 
I hope it works for you. Personally, I feel the double image you see when looking out the side view is just your system being over stressed. But, I hope I’m wrong for your sake!

I don't understand, I started from a complete clean system, and I still see the ghosting! 

 

I'm pretty sure that the system is not over stressed, actually the frametimes are enough good....

[imacken]

I can’t explain why, but it’s not always about frame times. 
If you turn down your SteamVR SS, MSAA, shadows, etc., do you still see ghosting?

Might want to check and see if you have HAGS enabled in your Windows 10.

Best to have that disabled if it is.

He’s got HAGS off, Don. We checked that a long way back.

Once I get the 90 FPS, and there is no need for reprojection, the ghosting disappears. Note that even if I see ghosting, movement is very smooth without stuttering or jumps. It is a perfect ghosting or double vision... (I have a lazy eye, so I don't expect any cross eye problem).

As said imacken, the HAGS is disabled. BTW, I use just the option 1 of the link you sent.

[imacken]

I mean not turning settings down so much that you are seeing 90fps. That’s too much. 
All I know is that I am on a fairly solid 45fps with little ghosting in side views at low altitudes. However, if I crank up SS or other demanding settings, then I do see ghosting in these circumstances.

I see, you mean lowering settings gradually until you perceive that the ghosting is disappearing at 45 FPS.

[imacken]

Yep, that would seem like a good plan.

I will do some trials. 
 

Apart from seeing ghosting in the side view, when rolling I also perceive ghosting.

[imacken]

All part of the same issue. 

[Nahemoth]

I have just passed a 3D Mark benchmark and it scores a good punctuation (with hyperthreading enabled, for DCS is disabled).

I started lowering and lowering, until I reached the lowest settings possible for 80% SS,  and it started working on solid 90 FPS where the ghosting disappeared.

 

I tried to capture the visual effect with my mobile phone but is quite difficult, and the videos that I got doesn't show the ghosting. Don't know if there could be an effect from my eye, persistence or something like that... or it is just that the refresh rate of the mobile camera is different (tried at 30 and 60 Hz).

[Nahemoth]

I'm in contact with the Vive technical support, I discovered some strange errors in steamvr when the ghosting appears, and they have started investigating. I also recorded a video with the effect...
