VR MP Performance (ghosting and other stuff!) SOLVED

[t-stoff]

I posted on another topic but I think creating one had better chances of a reply.
So.

I haven't been able to play for the last couple months but I think I've never felt this warp while playing in MP? whenever I bank the "screen" looks like its goin on 20 fps but I have 45/50+ fps at least (confirmed with the fpsvr app).
In singleplayer not as barely an issue (well its a little bit if a look sideways to the wing while banking). There's a lot of specific terms to describe VR issues, I don't even know if warp is the best, but it doesn't feel fluid, while I'm banking all the image gets distorted (I cant focus on anything) and it becomes jagged like when frames drop.
It doesn't feel comfortable to your eyes looking, and if you have a target ahead it will disappear on the distortion. 
I've tried a couple of setting changes but nothing seems to help 
Any clues?

On the other hand, spotting looks great!

I always experiment hiccups when banking, mainly on MP. For the performance impact you must find the settings that better works with your rig. For me, MSAA has high impact so I use FXAA and some SS (1.2 right now).

[t-stoff]

Thanks! Gonna give it a try! I could swear this didn't happen a couple of months ago.

[t-stoff]

Well, switched MSAA for FXAA and the boost in frames is really nice but the weird effect is still there. And it's terrible when trying to keep focus on the engagements ahead (and the slight nausea). Gonna try a couple of more settings change. Thanks for the help!

It might be your CPU spiking while your banking, I got a similar issue when attempting high settings along with ultra shadows which resulted in me getting cpu frame-time spikes when i switched from looking in the cockpit towards the outside giving me the "jitters".

 

fpsvr will show CPU spikes as a red spike upwards on the CPU frame-time graph on the right side.

[t-stoff]

Okey, gonna check that out! thanks!

What headset?

 

Try lowering all of your settings to get the fps as high as possible.  If the issue is still there it may be outside of the game - possibly the positioning of any lighthouses if you use those.

 

If getting the fps up helps, focus on that.  I've found that using Steam VR that if I up the hz to 120hz then it usually defaults to 60fps so play with the ASW or whatever your headset has.

 

It sounds like an odd issue though.

My performance was garbage until I reset everything in Nvidia control panel to default. Seems somewhere in a VR spotting guide on here I had made some modifications that were pretty performance negative, once I went back to default I probably gained 20 FPS. I have a 1080ti and I can run balanced w/2x MSAA and 120% SS on Valve Index for a pretty stable 80 FPS, even in multiplayer. Since the Index does 80hz native, makes for a really smooth experience. There are the random dips down to 70 but its not enough to bother me. Also running 5.0 Ghz overclock... Looking forward to 3080 whenever it's available for us non scalpers, should be able to boost settings and really enjoy the scenery.

Can you give your actual per eye render resolution? Since the % that steamvr gives is relative iirc. I'm struggling pretty hard in MP since the update with similar settings and I've got a 2080ti and a 9700k @ 5ghz. Though most of my frame drops are coming from my CPU and not the GPU, I wonder why your experience is so different.

I've thought about that myself a couple of times, if those changes were not counterproductive.

I'm beginning to wonder if I need a 'clean' Windows install, maybe on a second drive, where I only have the basics installed for IL2. My rig at the moment has all sorts of stuff on it -- IL2 mission editor, all sorts of Steam games, Visual Studio, Zoom, god knows what. Getting going with my VR rig already involves a reboot most of the time, so a dual boot probably won't slow me down much if at all.

I was messing around with my settings this morning. All the stuttering is CPU related. I'm purely speculating but the netcode seems to hold the engine from delivering frames to the GPU somehow as when lots of a/c are close by, shooting is involved, I see the CPU frame times plummet whilst my GPU is happily pushing 2300x2500 pixels at 90hz with 9ms frame times. Pretty frustrating. 

[ECV56_Lubermatz]

Maybe someday we will see an improvement for this. It has been a problem for a long time. Maybe the game supporting multi thread, but it needs an engine evolution.

Like all of yours, im having the same ram spikes that involves Shuttering, low framerate etc ( Oculus CV1 here) , then i try to switch from MSAA to FXAA to gain some FPS ,and it wont work , ( OFF, x2,x4 FXAA ) , Somebody have the same problem in FXAA ?

[ECV56_Lubermatz]

There is a post on Technical issues for that issue, since many of us are verifying that FXAA no longer works after 4.501.

CV1 here....MSAA and AA I see kill our fps...

I turned on FXAA and removed AA also.

I found good this setting also:

(STEAM VR using)

Settings - Ultra

Shadows - Medium

Mirrors - Simple

Distant Landscape Detail - x4

Horizon Draw Distance - 100 Km

Grass Quality - Normal

Clouds Quality - High

Target FPS - Off

Antialiasing 0

Gamma - 0.8

Full Screen

Enable VR HMD

Sharpen

Use 4k Textures

Vsinc on

 

in Ultra now I lfly in MP at almost stable  90 fps 

 

I use MSI laptop with rtx 2060 and i7

 

 

PS remove HUD when you fly by press H...eats FPS also !!

Ty very much sir!

[t-stoff]

I think I liked your settings.
Got for a few mins on Combat box and it seemed okey! over 50fps and the bank effect much more diluted.

Why vsync on - i Guess I have read not - ant it's only for screen ?

Yes I v to try without it...it remanined activated there from my past setting for 2D...

[t-stoff]

So quick heads up. Got a little busy again without playing.
In the meantime I bought Star Wars: Squadrons because it was on sale and jumped in. 
 
The same problem happened, everything is smooth as silk but as soon as I bank/roll the spacecraft everything is ghosting/jagged - I don't even know how to describe.

So, I decided to try everything and the solution that worked was to to scale down frequency. Went down to 60hz instead of 90hz

60hz was the key!  SOLUTION!

BOOM. Crystal clear! No more problems! No more jagged lines and edges. I can roll any "plane" in any game and the sides and horizon are sharp!! 
FPS went up. everything is much better now and also clearer 

;D

I'm happy!
still get shot down a lot. ?

Could be frames that are artificially created to continue high fps - re-projection or interleaving or whatever it is called.

It absolutely is, and considering it is resolved by going from 90hz to 60hz it seems we have frametimes that are reasonably consistently 45+fps, but with big hiccups down into the 30-45fps range.

(Yes, I know, saying frametimes and giving examples in fps. But we all know fps numbers better).

 

This seems consistent to my experience, and that of others. It is an MP-only effect and is CPU related. 

Out of curiosity, have you tried lowering your "preset" settings to low? It looks awful, but it actually reduces the compute range for projectiles (so if a dogfight is happening 15+km away it is no longer calculating ballistics for all the rounds)

Squadrons is fundamentally screwy in VR, I wouldn't rely on it for any kind of insight into what's wrong with someone's setup or a problem in another game.

[t-stoff]

I don't know if I got across, I'll try to resume again.

I played Star Wars Squadrons and it came with the exact same problem I was having in my two other games (DCS and IL2)
Apart from some of the problems this game has, it's much better optimized than IL2 and DCS! 
That lead me to believe it was a problem with my configurations, as my PC is good enough for at least a normal experience and not a horrible nausea one I was having.

So I went from 90hz to 60hz and all the problems I was having were solved. I havent tried to ramp up the settings looking for some more eyecandy, but I'm getting a ton of FPS and no more ghosting/stutter/stuff. 

sorry for the confusion 

Edited November 5, 2020 by t-stoff

[Dutch2]

Sorry but when I move from 90 to 60 in the WMR (in win10) I got a very stretched view. Were did you adjust that 60FPS and if this is inside Win10 WMR settings do you not have problems with having an unrealistic view, or is this only happen when having an Samsung O+. 

[t-stoff]

There's was no change in the view, the only difference is there's no more ghosting. Like when I was stopped and planes were moving around (air or ground) I could never see them as a continuous motion, but a series of slides. Same thing during a roll/bank. The horizon would turn all blurred and impossible to focus on anything besides the "HUD"/Sight. 
I'm using a Reverb G1.

I have PC very similar to yours and I can not tell what's best .... I just tried go in Mp with 90 and 60 and for me it's was almost the same .... 

90 to 45/50        or 

60 to 45/50 ....

So the lowest for me is the same ...

Well ,,it was a quick try 

My settings are 

[t-stoff]

I never had a big problem with frames in Il2, well "noticeable". I think it's much more stable now. Just on DCS, but who hasn't! hahaha
it was just the ghosting thing. And the funny thing is that you couldn't detect a performance issue when it happened.  
 

[SCG_Fenris_Wolf]

Ghosting always appears if you don't hold 90fps. The way the panels are, the ghosting appears even when just selecting 60Hz in WMR as well.

 

The stretched view is occuring for some (not all) WMR headsets when selecting 60Hz instead of 90Hz. IL-2 VR is optimised for 90Hz mode anyway, if 60Hz works on some consider it lucky.

 

I'd, by now, and especially with the expectation of the G2, would rule out 60Hz to be honest with you guys. It's just the way it is.

[NiiranenVR]

Donno , but I have heard that the stretch wiev should be something about an normal update in Windows 

 

1 time I tried long time ago I had it - but not anymore 

[SCG_Fenris_Wolf]

That what you refer to was fixed almost a year ago in a Windows Update

[t-stoff]

So, last night on MP server, 60 fps sometimes 58. as was on fpsvr app dash. 
 

[SCG_Fenris_Wolf]

That's way too low for competitive flying. Your perpedicular spotting and your gunnery skills will both improve with decent, stable framerates. For example: the more steady an aircraft flies over a forest below you, the more likely you can pick it up and keep eyes on it. If it ghosts around however, it is very easy to loose track. Then, velocity of target and vector are easier to estimate when deflection shooting with a high and stable framerate.

 

It's always worthwile to lower the preset one notch, and reduce horizon draw distance. These are things to begin with. GL.

 

P.S. Having a clean system is always advisable. Except for Nvidia's "prefer maximum performance", there's not much you need to do. You can smoothen out frametimes by increasing pre-rendered frames to 3 if you're a Pimax user, but I wouldn't recommend that to anyone else. If you read guides, please do so carefully.

Edited November 10, 2020 by SCG_Fenris_Wolf

[t-stoff]

I would say, from what I remember from fpsVR , it's stable around 60 (locked, almost) and GPU and CPU are not even on the red/orange.
What average FPS are you getting?
Later ill try to downgrade some of the gfx, but at the moment everything is smooth glitch free and the only handicap is my lack of skills ;D

[SCG_Fenris_Wolf]

I aim for 90fps.

Hey Rani, another 'primitivo' with a CV1 here.

Nice settings.  I've flown a couple of missions on Combat Box lately and this is really good for spotting.

 

Impressed!
