reported F14 VR - VDI screen not usable in MT Version

mdtenor22001 · January 11

Is this really still bugged? Just back to flying the Tomcat campaigns in VR. I can't see anything on the screen in the front seat either from the built in camera or the LANTIRN pod. Jester can see, and the symbology is there...just nothing but green (or black) screen.

Yes. Because so far neither Heatblur nor ED devs manage to reproduce the issue. It's hard to fix a bug when you cannot witness it on your own PC.

An idea has just crossed my mind: please ensure you run DCS from ".\DCS World\bin" (not bin-mt) and see if you can still reproduce the issue.

("bin" and "bin-mt" folders contain the same binaries)

bin is now the default... if so yes i can still repo

Flappie · January 11

Oh, you're right, I forgot that "bin" had become the default. False lead, then.

The weird thing is that it only happens in certain missions,and I can't figure out a pattern. I've been playing through Reflected's Speed and Angels campaign and the video hasn't worked at all. But random single player missions and online multiplayer it has worked. Surprised to see it has been such a long standing bug.

I didn't know this. I'll try Reflected's campaign and see if I can reproduce the bug.

EDIT: I don't have this issue in Speed and Angels either.

For me it only works when the mission starts in the air. That’s why in certain missions works, and non of Speeds and Angels work at all. May be something with the alignment?

Like explained in this very thread many times... it does not work in the first mission you run in DCS session. Any other mission runs fine after that. That's why the only workaround is to reload the mission you just started. Sometimes I forget about it after all the startup and try to consider... oh, will I need LANTIRN or TCS in this mission?

^^^^This is the point.

I find it quiteing that ED or HB are unable to replicate it.

Obviously there's some combination of software/hardware that triggers the bug while all others run fine.

Joe1978 · January 13

Well, sorry but this sounds similar to the response Orbx/ED about the SA performance issue.

The difference is that it appears HB has successfully reproduced it, according to this post.

Thank you, this is a known issue on DCS side, ED are aware.

Edit: no hate in my comment, it's just that this issue has been open since 2023. I greatly appreciate the work of HD

Once you see “this is on the DCS side” there’s literally nothing Heatblur can do, and DCS is on DCS’s “schedule” so expect delivery some time between Two Weeks, and the heat death of the universe.

Also I thought Razbam did SA map? Orbix did Kola.

Yes and no. Both maps are being made by (mostly) the same people, just under a different "publisher" - that's how I understand it at least. There are more details about it in other threads, since this has been discussed before.

Weird

CaptKludge · January 30

I had this problem every time playing single player. I had to do the quit each mission and fly again workaround every time. .. but ... I just cleared my nvidia shader cache and the DCS caches ... works perfectly now. Possible it was something else that fixed it, I have been messing with my graphics settings a lot lately.. but this was the last thing I did before it worked.

Which folders exactly?

Which folders exactly?

Probably all the folders you can nuke in Bailey's Witching Tool.

But there's nothing there that I don't clear manually before every patch (I even clear more folders than just those), and yet the VDI is still black on my end.

Flappie · January 30

Clear this folder (NVIDIA shader cacher, as indicated by @CaptKludge) and see if it helps:

C:\Users\your_profile\AppData\Local\D3DSCache

speed-of-heat · January 30

It does not

Flappie · January 30

Thanks for the test, @speed-of-heat.

@CaptKludge Can you confirm the VDI is not black anymore in your first mission run, right after DCS startup?

CaptKludge · January 30

Yep, first time into dcs, first mission run, so far works first time .. 4-5 times in a row so far. Like I said though .. I was messing with all kinds of optimization stuff in dcs and in the nvidia control panel ... so maybe the shader cache was not the magic sauce.

It doesn’t. I clear that folder every time I install a new nvidia driver so I would’ve noticed if it did.

CaptKludge · January 30

... I did both the nvidia cache and the DCS fxo cache. I just followed a youtube video

Awesome.

You are likely the first user to get free of this issue. Can you please attach what follows?

your options.lua (from Saved Games/DCS/Config)
a zip of your Drs folder (C:\ProgramData\NVIDIA Corporation\Drs - your NVIDIA settings)
if you're OK to install NVIDIA Inspector, an NVIDIA Inspector export
