Flickering rotors makes me feel ill in VR

Hi guys,

I have been flying my ass off since the AH-64D arrived on Thursday evening and I absolutely love it. And somehow all my Virpil stuff arrived on Friday, so it was just pure joy to fly a new module and test out all my gear.

But since I have been flying 64, the flickering of the rotors is starting to annoy me. Anyone found any way of reducing the flicker? I am already trying to beef up my sea legs in VR in this bird, but the flicker is adding to the discomfort. 

Anyone else having the same issue, or do I need to man up ;)

 

Thanks,

Simon.

Something seems broken.

In Mi-24 there is no flickering in the cockpit, even though there is rotor shadow on the ground. In the Apache, there is flickering in the cockpit and you can't see rotor shadow on the ground. It's like the condition on which surface to draw rotor shadow is reversed.

Blade animations are coming, already in the internal version, but I am not sure if it will solve the issues you are seeing. I will make this as WIP, watch the changelogs and let me know if it gets better for you. If not we can see if this is something we need to consider an option for. Thanks.

A note on the WWII props, they are much different than helo blades, and while they will be used for helos, it was not a straight conversion, much work has to be done.

ED has already figured out how to get rid of the flicker in the Hind. They just need to implement the same solution here. (And hopefully in older helicopters too when they find the time).

+1 me too. I don´t understand why ED did not implemented the same solution applied to WW2 planes with hexlix shaders... why not in choppers?

WW2 planes are doing 1500-2200 RPM. Helicopters are 350-450. Believe me, there is a difference IRL too.

That's still several times too fast for an accurate depiction on a monitor or VR helmet. 

At 100 fps without special gfx tricks you just get a massive strobe effect.

Not that it matters and it doesn't solve your problem, IRL helicopter cockpits it happens too. It's called flicker vertigo real pilots experience too, and it can be annoying. See attached...

Flicker vertigo occurs most often among helicopter 
pilots but also affects pilots of fixed-wing, propeller-
driven airplanes. Cabin crewmembers and passengers 
also experience its effects. 


Although flicker vertigo sometimes results in a spinning 
sensation, it should not be confused with vertigo, a disorder of 
the inner ear in which an individual feels as if he or she — or 
the surroundings — is spinning.

The famous words of a client/customer. They think everything is copy & paste. 🙄   Sorry, the developer in me got triggered with comments like this.🤪

I've struggled with flickering due to props and rotors interacting with things like projected gunsights in warbirds (and the IHADSS in the Apache) for ages, even since the supposed fixed were made. I finally managed to sort it out today.

If your using Steam VR, go into your settings and on the General page check to see if Motion Smoothing is on. Mine was, and as soon as I turned it off all the flickering in DCS disappeared. It's completely changed my VR experience, so worth checking.

This issue seems to be similar to the experience I'm having with the Mosquito propellors in Dcs at the moment. They were not always like this which seems to make me think there is a solution already in the sim.

I still notice this when I‘d engage motion smoothing in SteamVR. It‘s not only a flickering but an extremly annoying combination of flickering and blury, can’t describe it better, sorry.

I have never been prone to motion sickness in VR, but the effect causes me headaches in a short period of time. So I don‘t engage motion smoothing, which means I have to deal with my VR settings for FPS.

I‘d like to know if others still notice the effect in VR with AH64D to pin down if it‘s DCS or SteamVR related? Is it present in OpenXR as well?

You can try my mod, it has an option to disable rotor (only from cockpit view) for AH64, Mi24, Gazelle, Ka50: 

 

 

 

Thank you @lefuneste01

I know your mod….it‘s great work you have done👍.

I‘ll take a closer look into it for sure…..Thanks again.
