Cockpit stuttering on 1080

No, it's not.

No, it's not.

Yes it is. You're never going to be able to maintain 90 constantly.

Yes, not 90 FPS but playable FPS. With my 290X I had better FPS than with my new 1080. Therefore there is something wrong with the code of Flyinside. There is extreme lagging and stuttering and not just bad performance.

ATW remains constant if the setup is right on your system at 90. I have a 1080 with zero cockpit judder and still use the 368 drivers. My previous GPU was a 980 and the 1080 is easily better. I don't understand where you folks are getting judder from ?

I don't see stuttering on my system. My hardware is:

win 10x64 - Asus Rampage V Extrem - I7 5930K (OC@4.00Ghz)- Samsung 850 pro SSD - RAM Corsair 16GB DDR4 2800 - Corsair H100i - Asus Geforce 1080 - Philips BDM4065UC 4K monitor - oculus rift cv1 and a few other goodies

I downgraded my driver to 368.81 to be able to run HiRes without the flashes.

Best

Here's a theory, feel free to correct whatever might be wrong.

Asynchronous Timewarp works by rerendering the previous geometry from the current point-of-view whenever the application (in this case FSX/P3D) has not finished assembling a new geometry in time for the next frame. The logical limitation of the technology being that it cannot render anything that wasn't visible in the scene before, that's where we get the black areas when we look around when frame rates are really low.

It also appears to work better for distant geometry than close geometry, so I assume the relative position of the eyes or minor positional changes (ie. moving the head instead of turning it) are playing a role, so that we don't perceive any negative effects when looking at scenery, but we notice them when looking around in the cockpit.

Conventional wisdom seems to say that most people perceive a projection of any kind as kinda smooth when it has more than 24-30 fps. Apparently, this is different in VR, or we wouldn't have that "magical" 75fps/90fps number.

I think the people experiencing judder/stuttering in the cockpit (like I am) kinda expect that they get a smooth experience when turning or moving the head inside the cockpit, when the FI frame counter seems to be at totally reasonable levels like '30/90' or '45/90', but it certainly feels (to me!) as if the frame rate was only 10-15 fps, no matter what the FI window says.

Is this what everybody else is talking about?

I think we are talking past each other everyone.. Everything that goes below 90fps will induce positional tracking judder, not rotational.. ATW works only on head rotation, not positional.

Ahhhh but the new Asynchronous Spacewalk should sort that out for most

hahahah Spacewalk Yeah, Hope it will be implemented soon

Can anyone seeing stutter on 10xx cards try the just-released 373.06 drivers? Huge improvements
