Multiplayer in VR issues

[Loadie]

Hi there,

 

‘’I just started trying to use multiplayer in DCS; However, it sucks for me!
 

This is my system.

Aorus Z490MB

intel I7-11700K 

64GBRam

3 x M.2 SSDs

RTX3080Ti video card.

Oculus Rift S

internet is fibre optic getting on average 800mbps.

I haven’t tried anything higher than 100 ping rate.

 

when I try to fly, we’ll it all of a sudden gets unusable. Stupidly choppy, I lose the back half of the VR view. It’s worse than trying to wait for dial-up to connect, for those that remember dial-up.

 

any help would be greatly appreciated. I asked on one of the many the Facebook pages. The basic answer I got was DCS sucks in VR on MP.

VR for DCS in MP is achievable. I do it on less than you (Well, almost the same, I have a 2080S and a HP Reverb).

I don't know enough about the Oculus Rift, but the thing that has literally saved DCS for me was OpenXR.   30FPS is smooth in OpenXR (you wouldn't realise it's only 30FPS) and that's basically all I can get these days in DCS in MP. 

I'd also suggest starting small with your settings, and then slowly turn things up. Turn off MSAA, SSAA, Shadows, Grass, etc. 

However your problem may not be GPU but CPU related (depending on the server you are on). If you've got something to measure what your CPU and GPU usage is when it gets choppy this could be very handy. Have you OC'd your CPU? (I had to do that too for MP).  

First thing would be to determine what's causing the chop, and then look for solutions after that. For me - there were multiple things I needed to do before I could get it to work in a flyable way. Unfortunately as things currently are, DCS+VR+MP is not a PnP solution but requires some work in order to get the right performance.

But once you do - it's awesome.

The game changer for me was turning off ASW-mode in multiplayer. I was having great times in singleplayer (40 fps with ASW with Rift S in the past) but in multiplayer irradic stutters and spiking frame times - sometimes unplayable after some time because of constant stuttering and low gpu usage.

I think the irregular frame-times that are quite normal in multiplayer do no good for the ASW-algorithm. I tested this with Rift S, Quest 2 and Quest Pro. It all behaves the same way.

So my advice is, if you can live with irregular frames and no motion smoothing give it a try and disable ASW.

You could try 45hz forced in OTT (fps is then capped to 40 fps on Rift S) or you can try off - fps goes now unlocked up to 80 fps.

ASW-mode off is for me the only way right now to play in DCS VR-multiplayer. Had great sessions online on 4YA highly populated servers with 3-4 hours duration.

Give it a try.

P.S. And by the way your system should be perfectly suitable for VR in DCS, the 64GB RAM helps also alot when flying on Syria map.

another thing that can make a big difference is the cable that you use to connect the quest to your PC ...  they can vary massively is speed of data transmission

He is using Rift S - there is only the original cable thats comes with it. So no improvements there.

Thanks everyone for the advice! I can now play multiplayer with a few hiccups. For some odd reason I sometimes get the blue screen of death. Windows error memory issues. So I run the diagnostic on my RAM and 0 issues. Hop back on and play for a while. Other than that, not to bad! I really wish I could turn up the graphics more on multi though. Sucks with medium settings, vice the high, or extreme settings, lol
