VR freezing up in multi-player

Post by Sparky » Sun May 27, 2018 6:34 pm

My rig is:

Asus Predator 17 X Gaming Laptop - GX-792-77BL
Windows 10 Home
Intel® Core™ i7-7820HK processor Quad-core 2.90 GHz
17.3" 4K UHD (3840 x 2160) 16:9 IPS
Nvidia® GeForce® GTX 1080 with 8 GB Dedicated Memory
32 GB, DDR4 SDRAM
1 TB HDD, 512 GB SSD

I use the new Vive Pro VR headset. I briefly went back to the Oculus Rift but it froze too and this problem used to happen with the Rift before I bought the Vive Pro. All the USB controllers are set to not turn off to conserve power and all my USB ports and the USB splitter (not used for the VR rig) are USB 3.0 with the blue tab.

When I'm by myself it seems OK but when I'm flying near other aircraft my VR headset occasionally just goes black screen and my computer screen display freezes. I can turn on autopilot and sometimes it flies along and then the visual is back on if I wait long enough. I've tried rebooting the headset and on occasion it works, rarely. Often I must restart IL2. It's happened on TP practice servers and Wings of Liberty but not if I'd droning on in an empty sky, just when other a/c are around. Clouds don't seem to cause it nor does ground detail. I can low-level all day.

Sometimes it even happens when other a/c aren't around. On one of our recent missions I damaged my engine fighting the Spitfires so I was deadsticking it west looking for a suitable landing site when the headset went black. Luckily I had it trimmed up so when I got visuals back I was still gliding west but too low to set up for a good field and I had to bail out. But no other aircraft seemed nearby although I was in our TP mission server. Usually, even on our practice server, it lets me get near other a/c before I lose visual.

Any ideas?

Not a VR guy but one thing crrosses my mind: do you have the Il-2 installed on the HDD or the SSD (I assume you have your OS here too)? I know that it doesn't have exactly much in common with multiplayer issues, but I encountered similar bug with monitor screen in DCS. After I moved the DCS from my HDD to SSD, all worked like a charm.

I don't know. IL2 is on the C drive. What drive is the SSD? Do you guys think this could affect multi-player? The game in general?

Have you tried lowering the settings? what graphic settings do use in game? Do you use super sampling?

lower the settings and see if that works

I don't know what super sampling is.

Sparky, I'd try a couple of things

1) Read this, if you haven't already

https://forum.il2sturmovik.com/topic/28 ... nd-tricks/

2) While you're in the air, hit Backspace to see the frames-per-second that your rig can muster using your current graphics settings. If the number is near/below 45, then your computer is struggling and you should probably lower your graphics settings a bit.

3) Start your Task Manager before starting IL2 and click on the "Performance" tab. Start Il2 and, while playing, check the "Performance" tab occasionally (remove your headset and look at your monitor). If you see irregular spikes up to 100% in the performance graphs, try lowering your graphics settings.

4) Install something which can monitor your CPU / GPU / Motherboard temperatures (personally, I use Speccy https://www.ccleaner.com/speccy) and again, start it before you run IL2. Monitor the temperatures of your CPU / GPU / Motherboard. I suspect your CPU could be the problem as you only get problems when you have other a/c nearby which is usually more related to your CPU than other components. I don't think that is the problem but who knows.

5) Check your USB ports - try changing the ports that you use for your VR headset, if possible. You can also try and diagnose USB problems, try this guide

https://www.makeuseof.com/tag/dead-usb- ... nd-fix-it/

These are the things I'd check first. They might or might not work but I hope they will, at least, get you started.

Thanks, Gosho. That gives me a lot to work with.

After reading this the only thing I can say for definite is that it’s a problem with your PC as you get the same event with both headsets so it can’t be a headset or cable problem. Gosho’s advice sounds good for deducing where the problem is.

Excellent point. I'll follow Gosho's advice.

The 1180 chips are due out in July-ish and I'm afraid I may end up replacing my computer.

It is probably also worth contacting the support people for your PC to see whether they have a fix for it.
