Will VR be accessible from the very beginning? OpenXR, DFR, and other VR questions

About VR: I skipped it due to the head banging to unvisible walls in the cockpit. It made me sick instantly. If it will be the same nonsense in Korea, it is a VR NoGo. Eye tracking wouldn´t change the problem. Nausea is the main reason VR will never be mainstream anyhow.

Nausea and vertigo is the reason many potential pilots washed out of training. It's the same issue with using VR in a flight simulator. I have no problem with extreme roller coasters, barrel rolls and loops in a small plane, deep sea fishing in 8 foot swells, or VR. Some others are not so lucky.

Dear Developers, 

Now we are getting near to early access I would like to ask if IL-2 Korea will be available in VR with DFR/eye tracking.  Any information you are able to share regarding this issue would be gratefully received.  Thank you in anticipation.

Happy landings,

Talisman

No, this is not planned.

We have already investigated foveated rendering and conducted several tests. In our current DX12 deferred rendering pipeline, it shows only a very small performance benefit (less than 10%), which is not significant enough to justify implementation.

In forward rendering, it can provide noticeable gains, but that is not the approach we use, as deferred rendering allows us to support the full range of graphical features in the project.

We continue to research and prototype such technologies, but we only implement features that provide a real, measurable benefit to the user experience.

Does this mean I don’t have to use steamvr anymore on my pimax crystal to play il2 Korea?

I hate steamvr and it’s always bugged and acting weird for me….

Steam VR is not required even for IL-2 BoX (I don't have the standalone Steam version). It works for me without Steam VR, as OpenXR.

I don’t have the steam version either. How do you get it to work without steamvr?

Backup the old openvr_api.dll file in the game folder and replace it with this one:

That should work.

@MainstayHi! 

From Dev Blog 52, the team wrote this: New options include the choice of virtual reality API (Open VR or Open XR), the degree of image scaling using FSR (and now DLSS) technology, the inclusion of the pilot’s body in the first-person view, and a special VR-optimized graphics preset.

So you will be able to chose how to use VR and not depend on SteamVr 🙂

 

PS: I remember you from other sims and your cockpit re-textures! Had a blast with them. Really good to see you onboard 🙂

Can I use Open XR Toollkit with IL-2 Korea?

Can any of the beta testers 😉 confirm that OXRT works in the new title (in IL-2 BoX, everything is fine and OXRT works for me).

In theory that should work fine, with the caveat that Open XR Toolkit is no longer supported.

That's right, but it still works in every simulator I have, DCS, BMS, IL-2 or MSFS and everything is fine.
