Are you getting VR nausea?

I am frequent VR flyer in other sims and usually do multi hour flying non stop. I am very used to VR. I am using HP Reverb G2 with i9900k/2080TI and followed all the recommendation of lower my setting to med 60s.

For whatever reason, I am getting VR nausea after 15 ~ 30 min of use in FS2020. I am trying to pin point what is the root cause of this. I am flying GA Cessna 172 and not moving my head too much in the Seattle area.

Anyone else have similar experience of nausea only in FS2020?

Only when Iā€™ve tried Stunt flying in the Extra.

This is my first flight sim in VR, today I went from Vancouver to Seattle and I did not get nauseous at all in the a320, though I imagine if you have framerate issues or do aerobatics you can get nauseous.

I get a lot of nausea playing other VR games, so I am not special in that regard

Iā€™ve been flying around using my Pimax 8k today and did get a bit nausea when making sudden movements and quick turns, once I stopped and flew with slow turns it settled.

Iā€™m trying to slowly build up my VR legs so I only flew for about 30 mins in VR today

I think the game is having some problems with frame pacing and frame timings in VR at the moment, causing a rather inconsistent experience (micro-stutters and judder), which could be what is causing your nausea, especially if you donā€™t get it in other flight sims.

I believe this is what is happening. After doing a lot of reading I have manage to reduce significant amount of nausea by making 4 changes.

  1. Download OpenXR Developer Tool from Microsoft
  2. On the 3rd tab ā€œDeveloper Settingā€ make following changes
  • Turn on ā€œUse latest preview OpenXR runtimeā€
  • Check the checkbox ā€œCustom Render scaleā€ and set it to 70
  • Motion Reprojection as Always on
  1. In FS2020 change scenery scaling to 70

This helped a lot. Not totally fixed but at least flyable for more than 15 min :slight_smile:

Does that tool only work with certain headsets?

Are these changes persistent? Everybody keeps recommending doing this (or something very similar), but every time Iā€™ve tried, it just made things worse.

The tool is for WMR head set for sure. Other platforms are supported as listed here. The changes are persistent.
