[REPORTED]VR Performance OB 2.5.6

[speed-of-heat]

This is just a calculated value to point out the difference. dcs fps counter shows 22fps vs 45fps.

 

that's a difference of 23... not 77

No shadows?

 

 

For a mission with nothing going on, like the one I'm using to test, I aim for 80 fps. There's no way I can achieve that with shadows and AA. So, no - no shadows. I've found shadows to be a big frame rate hit.

 

It really shouldn't be necessary to have run at near minimum settings with nothing going on to just scrape 80fps on my PC. The same system with a 1070 / CV1, as it was before the deferred rendering "upgrade", I could manage 90 fps with better AA and plenty of overhead for when things got busy. But I digress... and I think I've flogged that dead horse quite enough.

I was expecting to see major shimmering jaggies around the outside of a small core, but to my surprise, I hardly noticed anything

 

I just tried the ka-50 instant action mission takeoff from Beslan. In this mission the light hits the cockpit so that straight edges shine. The mask can definitely be seen to be working here, I can tell you.

 

Is there no way that this effect can optionally be turned off? There doesn't appear to be any amount of AA that can deal with it properly, and it's shimmery jaggedyness is just dreadful in VR?

 

Other than in those conditions, what I described above does a good job imho of keeping jaggies at bay.

No shadows? OK saw your settings . from my point of view shadows even at low settings are essential for immersion...

 

 

I reckon turning shadows on ameliorates AA artefacts in the cockpit - like the ones I complain about in my previous post. However, that still leaves buildings and runways looking like crap in the scenery. It seems that you just can't win: I have to choose between shadows or AA as I can't have both. I refuse to run with ASW on 100% of the time - it's ok for flying an airliner, but not acceptable in DCS.

It is interesting that I get nearly the same frames in VR with 4x mssa and 2x msaa. Seems that 4x msaa requires less performance than before. But it looks way better. Perhaps the new VR mask helps to make 4x mssa usable in VR. With both I get low 30s in the coldstart mission. But only when I look to the tower. When I look in the cockpit I get my 45 FPS most of the time with my reverb. ED it seems you move in the right direction!

[imacken]

If you are still seeing issues I would suggest trying a few things.

 

First would be make sure you are not using any unofficial mods.

 

Run a cleanup and repair. or verify for steam users.

 

Rename your dcs.openbeta folder in saved games ( keep it as a backup )

 

restart DCS Login and redo your settings and test.

 

this will ensure you have a vanilla install and new shaders.

 

You can return to the backup file after or copy over your inputs.

 

If you still have problems let us know your system specification and in game settings.

 

thanks

All done and with my settings, I can't use MSAA with or without mask. See attached on Super Carrier as an example, and that;s without MSAA!

 

Now, in normal flight and without too much going on, I get a steady 45fps with frame times from 12-20ms, but when there is a lot of stuff going on, I'm down to 30fps and GPU/CPU frame times in the mid 20s. (See attached.)

 

Anything on the SC shows this, or my goto test is to sit in the Hornet in Home on the Range and watch the Warthogs taxi past and take off. Look to the left, OK, look to the right where the Warthogs are and horrible.

 

Same when flying over North Vegas airstrip, etc.

 

My settings as per 2.5.5 and previous 2.5.6 are generally high/med, low shadows, no MSAA, PD 1.0 and SteamVR SS of 200% (equivalent to PD of 1.4).

Ok tested a F16 freeflight an 4xmsaa is still Eating up FPS. Seems that something else is FPS costly on the supercarrier

I was expecting to see major shimmering jaggies around the outside of a small core, but to my surprise, I hardly noticed anything - nothing like what I get with AA off. I am running 2xAA in DCS, and enhancing in nVidia Control panel as detailed here. Who knows how the settings are interacting with each other. Whatever, the upshot is I'm getting a result I'm happy with.

 

 

After further testing, what appears to be going on is that the mask affects "DCS's" AA, but does not affect nVidia's MFAA, which appears to still be applying to the entire image. Using MFAA in addition to DCS AA was recommended to me on here some months ago as a way of getting 4xAA at the cost of 2xAA. It seems to have almost no performance impact, so I recommend it to everyone in turn.

I've always had MFAA on, although don't really know why as I can't ever see any difference if it's on or off!

I'm surprised, as that's not my experience. I would suggest you try flying around 2000 ft around 2nm from a city:

 

 

 

1. With no AA whatsoever

 

2. With 2xAA w/ mask 0.1 in DCS

 

3. With 2xAA w/ mask 0.1 in DCS + enhance AA X 2 w/ MFAA in nVidia.

 

 

and see the variation in building jaggies in each case as you pan your view. You must restart DCS with each change for the change to take effect.

 

 

We have different HMDs (and no doubt DCS settings). Maybe it's down to that.

Sorry, ignore my last post. I was thinking FXAA!

 

I'll go and experiment with MFAA.

So, I tested this out, and I can't really see a difference between 2 and 3.

 

The thing is, DCS is totally about a balance between shadows, MSAA and rendered resolution. Nothing else makes much of a difference in my experience.

 

Personally, I don't use MSAA as I prefer to have low shadows on and a high SteamVR SS rate of 200%. I would love to have MSAA x4 and shadows set to high as well as a high render res, but it just isn't going to happen with the current hardware. Oh well...

That's what I used to run, currently trialling 100% SS only with 4x MSAA and 0.1 mask. Image quality seems to be worse so far but spotting may be slightly better.

 

I always thought the advice for VR was "in game MSAA is crap just supersample instead", but I keep seeing conflicting advice.

MSAA and SS do very different jobs as I'm sure you know. In my opinion, MSAA doesn't do anything to improve image quality except reducing the 'jaggies'. Jacking up SS if your system can handle it is the most important aspect of image quality.

[VC]

MSAA and SS do very different jobs as I'm sure you know.

 

Do they? My knowledge is that they do a very similar job, almost the same, but MSAA only looks at edges while SS does the whole image including textures.

[gorzasty]

I decided to check DCS after more than a month... updated everything, deleted shades folders and set VR setting in the menu. PD=1. Than turned on free flight mission in Mi8. GPU render time was over 20! Wow what the hell!? My specs i5 8600k@5GHz, 16GB Ram 3200MHz, 1080ti. HP Reverb. Steam SS at 100. My framerates were at 30fps (asw for 60Hz).

 

On 2.5.5. I could get 60fps and a much higher settings. This is terrible. Unplayable for me. Some real bad things has gonna happend here.

 

I'm very disappointed. I bought so much of your modules, so much money put into and now it is unplayable. I know there is a stable version, but there are no servers online with that. All my friend without VR play at 30-50fps on beta servers and say same thing - what a bad optimizations.

HI GUYS, I THINK THIS MAY BE IMPORTANT TO SOMEONE STRUGGLING WITH VR...

WHEN STRARTING STEAMVR, I SAW IN THE TASKMANAGER THAT THERE IS A STEAM PROGRAM AUTO LAUNCHING WHICH IS....STEAMTOURS...THIS IS TREMENDOUSLY TASKING THE CPU FOR ABOUT 12 TO 15%

I AM ON I7 8700, DISABLING IT DOES NOT CLOSE STEAM VR AAND YOU ARE ABLE TO LAUNCH DCS.

IF YOU EXIT TOUGH, IT STARTS AGAIN

Never seen Steamtours in my Task Manager.

[boedha68]

I gonna try it tonight. :D Thanks.

[Lanzfeld113]

It’s not in my task manager

[speed-of-heat]

nor mine... i think it is the steam tutorial? has he finished the set up ?

[vracan]

no steamtour neither in mine.

Nice try

[Lanzfeld113]

I have a 9900 K at 5.0. I have a 2080 TI overclocked. It’s strange because I normally run very smooth HP Reverb at 150% set in steam VR and nothing set in DCS it’sself. But when I get on the super carrier sometimes when I look near the tower or the middle of the ship I get stutters. Also sometimes in the ground attack area. The program can run like butter sometimes and other times it stutters. I think it is a DCS optimization problem.

 

The server had about 30 people on it. Is that too much?

[hannibal]

i hope some one makes an updated DCS VR optimizations guide!
