Stuttery VR head movement

Most of the time my VR tracking (Rift) is smooth. But from time to time when I fire up a mission all head movement becomes extremely stuttery. If I restart the mission, or alt tab out of the game then back, it usually goes away and returns to being smooth again. What can cause this?

ASW is normally the cause if you turn it off you should be fine as it is no longer trying to lock 45fps.

When that happens for me, I turn ASW off with Ctrl Num 1, then turn ASW back on for constant 45 FPS with Ctrl Num 3.

Just a quick question: does this key-combination relate to DCS or another service?

Those key combinations are for the Oculus Rift software, and they work within DCS.

Here's a link to the Oculus page that relates to ASW commands.

Thanks for the quick reply.

unfortunately I use Windows7, they are saying I need Windows 8 (or later).

Man ... :doh: Why does Oculus think I have nothing better to do than installing this f... sh.. systems. Why? Who told them?

OK, I can live with that. ASW is normally turned ON, is it?

Not with Win 7, you have the older ATW system for Rift.

Really to get the most out of VR devices you need Windows 10.

Thanks for this valuable info.

It didn't ever realize real problems with framerate (always 45 or more), so I didn't care too much about all this. But I think ATW is a good thing, and Windows 10 on my harddisc will work, indeed ... only over my dead body :smartass:

Hey I was just answering your question, obviously you are free to do what you want.

Hey, I know! Bad communication from my side, sorry for that!

I thank your for your answers and bringing light into my darkness!! :)

I wasn't aware of the system limitations regarding W7 <> W10.

It doesn't seem like ASW. It's more like a vibrating screen as soon as I move.

The HMD cable can cause this as well when it gets wires the break, check for a lump just after the clip on the head band.

Also check Oculus is happy with the sensor(s) i.e not red test for them.

That sounds like the problem I had (have?).

FPS were a silky smooth 90, but as soon as I moved my head, the entire picture started to stutter, while FPS stayed at 90.

I googled this and found people with similar problems.

Some people reported that turning ASW on and off a few times, solved it.

Others simply took the HMD off, and put it on again (or took it of and used a finger to activate the proximity sensor) a few times.

Others seemed to correlate this with MSI Afterburner or ASUS GPU Tweak, and similar GPU overclockers. Even ASUS Aura could be the culprit.

I uninstalled the ASUS software I had installed, and haven’t seen this problem since... Fingers crossed!
