Please describe your issue in as much detail as possible:

When you move your head around it is noticeable that the tracking of the HMD is somehow delayed and not smooth. This is especially clear if you have tried SteamVR for Windows before.
Also the tracking of the Controllers seems to have the same issue: it looks like the position is being interpolated/approximated and the movement isn't smooth and instantaneous like on Windows.

This issue is really annoying for the HMD because it makes the experience really unpleasant and, after a while, nauseating.

This happens with any linear combination of AsyncReprojection and AllowReprojection (both on, both off, only one of them on).

It is most noticeable while playing some game like Destinations or SteamVR Tutorial but, to me, it is also clear inside the SteamVR environment.

Steps for reproducing this issue:

1. Start SteamVR
2. Look around and focus your attention on static items like the chaperone bounds
3. Start Destinations or SteamVR Tutorial
4. Repeat step 2

Can confirm, the controllers have ghosting as if they're interpolated. Also the headset movement is delayed, which makes me sick after a few minutes. It's like the world moves around you, instead of you moving around the world.

Performance and latency aren't currently expected to be optimal when a VR application is running, but should be comparable to the Windows version in the default SteamVR environmnent. Is anyone seeing subpar performance when no application is running?

[odensc]

@Plagman The SteamVR environment works great - it's a night and day difference vs the tutorial.

[leinardi]

@Plagman I first noticed the issue in the SteamVR environmnent, from the first time I started it. Isn't obvious as in Destinations or SteamVR Tutorial because is mostly an empty space but, if I turn my head looking at the chaperone or a lighthouse, I feel that something is wrong.

yes, at steamvr enviorement works correctly, it's when a application is running that delay appear, as more consuming more delay. At serious sam i have a huge delay at tracking, more than tutorial.

@Plagman I can confirm this is happening on my system, too. The tracking is noticeably slower (or it is my perception as slower). I've noticed this delay in the SteamVR environment from time to time, too... But it happens in every application, period.

I tried updating my kernel to last 4.9 and disabling desktop effects on kde, but still the same.

@Plagman I can confirm the tracking inertia. It appears in every application (including really simple Unity scenes) except the empty default environment of SteamVR. After loading a custom 3D obj-based SteamVR environment (for example the Rick and Morty garage) the latency get's noticeable there, too.
Since the delay seems to be the same everywhere, I guess that it is not dependend on the application performance itself and maybe lies somewhere in the tracking data pipeline. The latency is not present in the display mirror (Chaperone grid and Unity scenes move synchronously and align perfectly) and only inside the HMD.
Also, the Chaperone bounds are never lagging. This feels similar to the the latency problem with UE 4.12.

The March 6th build of SteamVR makes this much worse for me. I'm running the .13 Nvidia driver, too. Now, the steamVR environment really shows this much worse.

[aronschatz]

The March 10th build seems to be moving in the right direction. The SteamVR environment still lags (noticeable when moving your head up and down, less so when right to left, but it is much better than before.

I'm noticing this with the March 16 build as well, especially if you stand still and wiggle your head a little -- the delay is considerable enough to generate nausea (in the StemVR environment). In the SteamVR tutorial, the delay is exaggerated even more so. Running Ubuntu 16.10 x64, Nvidia GTX 980ti w/ 375.27.13 Vulkan proprietary drivers, Unity 7.5.0 desktop environment, Linux kernel 4.8.0-39-generic.

I still experience this issue. Performance seems fine, but everything is noticeably delayed. Running Linux Mint 18.2 (based on Ubuntu 16.04) with Cinnamon, NVIDIA Driver 384.69 with a GTX 1080.

The delay happens everywhere including chaperone bounds, SteamVR Home and the standard SteamVR environment.

@Plagman Any news on this issue? it's been 7 months already :'(
