Aside from a whole bunch of people congratulating 1c over on their forum for adding VR support... no one has actually reported playing it in VR.

I've spent more than an hour trying to get it to run and I know someone else on steam also unable to get it running.

OK well it's not just me. It's broken for everyone with VR.

OK well there is NO VR support for IL2 Battle of Stalingrad.

I got a reply from the developer on steam and he said I have to take Vive out of direct mode. Sure enough the sim does run on the Vive in that mode but it's unplayable. You can't see the menus unless you set GUI FOV to zoom out and if you do that then you're not actually in a lifesize cockpit but a miniature one.

There is no real VR support here so I suggest you update your information.

OK. Well it does start in VR with direct mode off but it's unplayable. You can't really expect people to play it this way? To start with you can't access the menus because the FOV is too great by default. GUI FOV. When I reduce that as recommended to 0.5 then when I'm in the cockpit it's very small. I'm in a toy plane instead of lifesize.

So the question is how long before you implement WORKING VR?

I purchased this because SimHQ said you added Vive support. Your steam page says you added Vive support but having to switch out of direct mode in steamvr is not acceptable.

I invite people to try it and see what I mean. Imagine Vorpx without the option to adjust FOV or use the image peek feature. That's how it looks.

I'm going to request a steam refund unless you have some sort of ETA for fully operational direct mode Vive support."

Update:

Still very early days for VR support and devs seem to really want to continue developing for the Vive. I am happy they released the VR implementation even though it is not optimized yet. Ive managed to get my OR CV1 to at least get into the cockpit and fly around without the headtracking so far... more testing to come. Hang in there...

Impression of one that manage to run:

I hope they continue to flesh it out.. then get it working on the Rift also.

The issue with Rift is the game engine be in DirectX9, no longer supported by Rift.

Agree. It's good they're developing it. Just a shame they haven't got it working in direct mode.

I thought the lack of direct mode was a consequence of using DX9 but apparently not. Nolimits2 runs on DX9 and that works fine in the Vive's normal Direct Mode.

That's strange. I'm pretty sure nolimits 2 uses DX9 (it comes with that redist and doesn't run unless DX9 installed) and it runs on CV1 and now Vive.

Interesting... It seems he is able to run it a bit more smoothly than me. For me it's unplayable. I have a faster GPU but my CPU is much older. Seems like my CPU might be holding me back.

The VR mode looks great, but in most cases it doesn't seem to run at the right framerate for the head tracking, probably because retroprojection doesn't kick in when needs to keep the head movements in sync with 90fps.

I've experimented a bit and turned on the forced "always on retro projection" option, as well as actually forcing IL2 to a 45 fps limit, which should be feasible and the right spot to force retro projection - not ideal but if retro projection worked it should have produced relatively smooth head movements (at the cost of artefacts though). That didn't work, it still very much felt like what I was experiencing was 45 fps for everything, rendering and head movements, so either the fps was even lower than that or retro projection wasn't kicking in. There's an option to display some of the performance stats in the hmd while in VR so I'll do that next.

It's also possible that there's a bug where the hdm syncs at the monitor refresh rate - that used to happen in the non direct mode days of the Oculus DK2. Direct mode would fix that. So here's hoping that they had a (or some) dev(s) working on it!

DX9 isn't supported by Oculus, but that doesn't mean that BOS can't implement support for the Rift. Oculus dropped DX9 support because it was easier to get VR to work more effectively with later DX versions. You can have the best VR headset, but VR could be killed by bad VR software, especially when the software wasn't built specifically for VR. BUT after Oculus dropped support for DX9 games, they developed ATW software which should really help less optimized DX9 games work more effectively, IF those games can run close to 90fps. Complex flight sims are usually challenged in that regard. Hopefully the find a way to support the Rift as its the HMD of choice for most in cockpit games. Example, a youtube video from UKRifter, who owns the DK1, DK2, CVI, and Vive. He loves both the Vive and Rift, but uses only the Rift for all cockpit type games, and Vive for roomscale games for a number of reasons, some specified in the video.

Hmm...

I'd love to try it out with my Vive but I'm not willing to shell out the cash since WarThunder works great.

Guess I'll wait a bit.

I played with BOS all night yesterday and it was great.

I'm on a Vive with a GTX 1080 card.

Interesting Valar - if you played all night I'm guessing you had no judder at all. I wonder whether it's simply the GTX 1080 making it cross the line at a constant 90fps or whether there's something else that makes it work for you.

GTX 980 here with overclocked i7 3930K @ 4.4 Ghz but I seem to be stuck at low fps and retro projection doesn't kick in as it should - could be performance, could by some sort of issue with non-direct mode imposing a max fps on the Vive which isn't 90fps - these sort of bugs happened during the non-direct mode era of SteamVR: for a while I couldn't get E:D to run without severe judder and it turns out there was a bug which made steamVR run at low fps due to a weird interaction with my monitor. It could be the same sort of thing or performance. I might find out soon if I end up ordering GTX 1080s at work - they might end up temporarily in my home PC, but it will be for Science!

How exactly did you get the vive to work? It's the only game I have that wont work. P3d is great, DCS is great BoS just wont work. What settings did you use and how exactly did you get I to work?

Yep, I'be curious to know how Valar did it indeed. I could launch the Vive in VR but it was a juddery mess - it's possible Valar's GTX 1080 gave him the extra fps to reach 90 fps without any retro projection while my GTX980 can't pull that

Ok I got it to work. Heres what I did
Uninstalled then re installed BoS
In Steam VR settings
Developer
Disable Direct Mode
And check "Enable Always-on Reprojection"
In
/1C Game Studios/Il-2/Data
open Startup.cfg
or_enable = 1
or_fov_gui = 0.5
or_fov_h = 1.00000
or_fov_v = 1.00000
or_height = 1680
or_ipd = 0.06220
or_lens_offs = 0.02891
or_width = 1512
The GUI is garbage. Unlike other VR programs the GUI will follow your head movements. Very hard to use.
Also I found myself having to re-hit the il2 taskbar button as I'd hit the mouse outside of the il2 desktop display.
Its not perfect but ingame it's actually pretty good. I've found it smoother than DCS, less flickering.
With all VR I think with programs like BoS where the textures are of a lower resolution it actualy helps with the current low resolution VR displays. I hope you get it working and I hope this helps

Thanks for the details. Unfortunately, I've got the same settings, including the always on retroprojection which I thought would solve the juddering issues - I can make it start in VR, no problem, but once in a mission when I look around it's juddering like hell. I checked my GPU and CPU performance and in fact it's not maxing them at all, far from it, and the Vive performance tools don't show skipped frame either, instead it looks like it's not syncing at the correct fps - and this part is not necessarily surprising as I had issues with non-direct mode and steamVR in the past where it did exactly that because of some bugs where the monitor setting interfere with the hmd. I guess I'll have to wait for when they'll start using direct mode properly
