Recurring 'flashes' in VR

I get recurring yellow ‘flashes’ every 3-7 seconds (guestimate) in my VR headset, which is extremely annoying. I suspect it’s some grahpical artifact caused by the ligh model and may be connected to rendering external aircraft or airport lights, as they seem to be a bit more pronounced in that environment, but they do persist after takeoff and cruising. I no longer play MSFS2020 but I saw the same thing in that sim.

Anyone else seen this?

Do you use TAA and are the flashes near your bottom field of view? If so, there’s an existing bug report on that.

If you are using TAA, make sure it’s set to 100%. The flashing lights bug is related to TAA plus scaling.

Sounds plausible. I am indeed in TAA and I later set render scaling to 100%, because I didn’t need scaling with my stronger hardware now. And, your right: I haven’t noticed the flash bug since.

Thanks!

I experience this issue too.
I did run TAA at 80%. When switching to DLSS I don’t see the flashing anymore.
But DLSS sucks, and TAA above 80% is too heavy on my GPU (I get a warning saying that my GPU memory is too high when I increase the TAA abover 80%)

The flashing is a little different in different aircraft. In some, i.e. the Cub, it is more like lights flashing, while when flying the F18, it was a faster total blue flash.

This seems to be a bug that has lasted for quite some time, and not been fixed…

(I recently moved from 2020 to 2024, and generally like 2024 better, but I get much more bugs like this one in 2024. I also get some total crashes and some serious stutterings sometimes. 2020 seems to be much less bug-free, even now after 2024 been out for so long….)

My specs:
RTX 5080
Ryzen 7 5800x3D
64 GB DDR4 RAM

PS: I have tried to turn off hardware accelerated gpu scheduling, but that didn’t fix the issue.

So, my temporar solution is to turn down the graphics settings to be able to turn up the TAA above 90%. Then everything works fine. Now running at “High” settings with TAA at 100%. Works acceptable.
