Swift. Posted April 4, 2022 Share Posted April 4, 2022 When you move your head around whilst using the PNVS there is a noticeable stutter in the image, compared to when using the TADS and the image is silky smooth throughout. The PNVS feed is smooth when you aren't moving your head so this looks more like the actual PNVS itself is stuttering as it moves through its motion. To Reproduce: 1. Use the PNVS 2.

Jagdgeschwader Posted April 4, 2022 Share Posted April 4, 2022 Maybe it's a small delay in the PNVS operation? It is, after all, a sensor that copies the movement of another sensor in IHADSS so it can cause a little delay. That's how I think it works, I may be wrong here.

Perhaps, but why is the TADS so smooth then? As that's also 'copy another sensors movement' when used as a NVS like this. 1 476th Discord | 476th Website | Swift Youtube Ryzen 5800x, RTX 4070ti, 64GB, Quest 2 Link to comment Share on other sites More sharing options...
Crptalk Posted April 4, 2022 Share Posted April 4, 2022 It does seem a decent bit smoother in actual PNVS footage than how it is currently in game. 2 Link to comment Share on other sites More sharing options...

Ah yeah perfect example, it just looks like how the TADS is now, but faster.

Move your head I am with you. I fly the Apache in VR and it is very noticeable with the PNVS compared to the TADS. The response time and movement is of course better with the PNVS (TADS takes longer) but it shouldn't be that "stuttery". The PNVS definitly needs some more fine-tuning in smoothness.

ED Team NineLine Posted April 4, 2022 ED Team Share Posted April 4, 2022 I have asked the team and out SME's, last I heard they were happy with it, and that there is some lag to be expected if your head turns are too quick. But I will report back. Also, I cannot stress enough.... include tracks. Why? I can load up your track internally and see exactly what you were seeing and see if there is any improvement over OB release, I know that some of you hate giving tracks, but they are very valuable in 99% of reports.

Thanks. Great points. One thing I'd like to point out though. I think everyone understands that the slew rate may not match your heads rate. Its the stuttering that people are pointing out not so much that it lags behind your line of sight. So yes if my eyes are looking at 156 the sensor might be at 123 because its slewing over to 156. But during its translation its stutter stepping its way which is off putting and not visible in the Cosmo video. It translates around at a smooth rate. Its most noticeable if you move your head left to right at a slow pace. One that the sensor could keep up with. I also wonder if VR has some fault in this when its doing frame interpolation. For instance running at 45fps. Link to comment Share on other sites More sharing options...
Swift. Posted April 5, 2022 Author Share Posted April 5, 2022 Also worth noting, as nergized said, it only seems to happen when you move your head slow enough for the sensor to keep up. If you whip you head fast, it seems a lot smoother. I'll do a track today 1 476th Discord | 476th Website | Swift Youtube Ryzen 5800x, RTX 4070ti, 64GB, Quest 2 Link to comment Share on other sites More sharing options...
nachomaga Posted April 5, 2022 Share Posted April 5, 2022 Swift, the opposite happens to me in VR, hehehe... 9 hours ago, NineLine said: I have asked the team and out SME's, last I heard they were happy with it, and that there is some lag to be expected if your head turns are too quick. But I will report back. Thanks for reported back. Anyway, even with slow head movement, PNVS seems more laggy than TADS. I said in another thread, in day light I even see a bit of stuttering in PVNS sensor movement in the nose. I’ll do a track too. Link to comment Share on other sites More sharing options...
Lurker Posted April 5, 2022 Share Posted April 5, 2022 Does the stutter happen only when you move your head? If you are looking at a fixed position and turn in the helicopter, does the stutter appear?

nachomaga Posted April 5, 2022 Share Posted April 5, 2022 @NineLine here you have the track. Anyway, I watched in VR but the the head movements are not visible. In 2D movements are visible.

River Posted April 5, 2022 Share Posted April 5, 2022 You guys sure it's not PNVS AND scenery stutter? PNVS gives a huge FPS hit so maybe it's not only the PNVS that stutters. My whole game stutters when I use PNVS or mirror TADS on a MPD. 1 Link to comment Share on other sites More sharing options...

As I said before, when helo is turning and head more or less fixed, PNVS video is very smooth, like all scenary around.

Stays 40 fps with / without PNVS. GPU load climbs from 70% to 85%, thats it. So no framepacing or FPS-drop issue here. Its stuttery with slow and fast head-movements.

frostycab Posted April 5, 2022 Share Posted April 5, 2022 This is just pure speculation on my part, but if it’s only really noticeable with slow head movers then to me it sounds like the polling rate might be set too low. If the PNVS only gets your head position every 250ms for example, it’s going to look quite juddery with small, slow movements. The lower the polling rate, the more notchy it would appear. 2 Link to comment Share on other sites More sharing options...

He's talking about how the PNVS does not appear to smoothly pan/tilt in the first place, but rapidly "step" across positions. It's most visible in the video he posted when tracking a passing scenery object with his head. You can see how the PNVS "steps" to pan instead of panning continuously. What he's showing would not be physically possible in a real sensor. Edited April 15, 2022 by Jester2138 1 Link to comment Share on other sites More sharing options...

It’s never been explained so well, thanks Hope ED find the problem, I’m loving the Apache, amazing module, but I’m not flying so much in the night because of PNVS problem. I use TADS instead (bit more smooth) but of course CPG needs more than me, lol. Link to comment Share on other sites More sharing options...
ilikepie Posted April 19, 2022 Share Posted April 19, 2022 some of our guys using vr have had a similar thing, Quote Just did some testing , setting cockpit displays to "every frame" makes a noticeable difference to the smoothness of the IHADS FLIR picture in VR. Without every frame selected, it renders every second frame, but because you have it set to render in one eye, which is half your referesh rate in VR it's actually rendering at half that again, or at quarter frames.
