Thanks! I haven't, I'll get reading. I've been using the G1 for a year, but am expecting my G2 soon (along with a 6800XT and Ryzen 5800X) - so wanted to get knowledgeable ahead of time.

So I don’t want to muddy the waters here, but have just spent an hour testing different settings. Bear in mind my PC specs, but what is going on here when I can change the steam VR from 48 to 100% and the DCS app setting to 200% (!!!!!!) and still get around 50 FPS and GPU frame times of around 19 or 20? (which was what I was getting using 48% and 100%).  Surely that should have massively affected both performance and quality? I noticed an improvement in quality, but not huge ( cockpit stays the same whatever I set, it’s the terrain and objects I can see better) and a decrease in performance of maybe 15% In GPU frame time ........

 

I restarted DCS each time as well.I am obviously going to investigate further tomorrow, but this has me scratching my head.

Yup, it's strange behaviour. Got my G2 last week, first foray into VR and have been fiddling and questioning ever since. Came from a 2D TIR setup with an OC i7-6700K and 2080ti smooth and frankly great experience pretty much max settings on a 3440 monitor. Then came the G2 OC'd i9-10900K and 3090 (was expecting great things) did the "what SS percentage? " dance for a few days, then the "lower all my settings" shuffle, saw minimal change to my CPU frame times and sub 45fps, and was immediately reminded of how much time, effort and money I sank into the dead horse known as FSX. Frankly VR performance in DCS is crap, you can follow all the guides but if you want anything approaching the clarity achievable in 2D it's not going to happen. My honest opinion is the entire game and its rendering subsystem needs dragging out of the noughties. ED have "customers" here that have spent circa 4K on hardware (without) HMD costs that are getting frame rates and user experiences that are quite frankly dire given the compute resources in use. Back to TIR and a big monitor for me. It needs fixing......

This setting was the trick for me.

 

Unfortunately there is no way changing this setting could have any impact on DCS VR performance, as it's a totally different API than what DCS uses (OpenGL vs DirectX). Might I suggest re-testing this setting in a standardised environment and test scene and then posting your findings. I think it's best not to promote incorrect settings as fact, as the combined effect of dozens of these "facts" make it both confusing and time-wasting for users trying to obtain a playable VR experience.

[Coolhand77]

You are right, changing this make no difference after some testing.

But resetting to default and then use the same settings as Bignewy made a difference for me. Unclear what setting that made the difference.

 

I also tried the 60Hz mode now. And that works even better now. Superstable at 60fps and no ghosting.

Most people can't stand the horrible flickering/strobe type effects that come with 60Hz, but if it's good for you, then great!

[BIGNEWY]

I could not cope with 60Hz, it was not good for my eyes.

ditto, i thought i could; then i started getting headaches

Agreed, migraine inducing for me too. And like going back to 80's CRT's

[Rocky49]

So I’m a little confused.  Is the goal to get the frame rate hold 45 FPM using the supersampling option or lower the settings to get 90 FPM?

[imacken]

Totally down to personal choice really. 

[Rocky49]

My goal has always been best graphics at highest frame rate possible so what track would that place me on? Isn’t Super sampling “locked” on a threshold of 45 FPM?  I’m currently running at 74% of native resolution.  I’m barely holding 45 Frames in Syria.  I’m using exactly the same setting in Nvidia and DCS as posted by BN.

Everyone's machines are different and using my settings may have different results, if you are not getting higher frame rates you will need to investigate what is going on, even when I test higher settings I am getting 45+ average in the 70s

Strange, I am using 60hz and notice zero visual artefacts or flickering as you guys describe.....in fact the opposite holds true for, using 90 hz makes it run juddery and blurry for me........

As we discussed in the other thread, I think there is something wrong with your setup. 
The problem with 60Hz is that most people see horrible screen flickering with the lower refresh rate. The other issue is that if you have motion reprojection working correctly - which as we discussed, I don’t think you do - then you will see 30fps rather than a rock solid 45fps at 90 Hz.

@markturner1960 on this link, find “to enable motion reprojection”, below that there is a video explaining how to enable it.

For me reprojection didn’t work until I did these steps.

https://docs.microsoft.com/en-us/windows/mixed-reality/enthusiast-guide/using-steamvr-with-windows-mixed-reality

 

also I think you should try out going back to 90 hz and enable the reprojection always to get a steady 45 fps. This can hopefully result in a good experience. 
it does for me.

This is a pretty important, and commonly overlooked, line from the WMR guide

 

Quote

For SteamVR games that reliably hit 60 FPS+ on a given PC, this should result in a solid 90 FPS experience with occasional artifacts while maintaining a comfortable experience.

 

So the goal is not to hit 45, but to hit ~60. If you are just managing 45 then you are going to get dips below 45 at which point the reprojection will turn off and you will get "stutters". My goal is to get to a steady 60fps so reprojection can do its magic. Turning the reprojection indicator on is very helpful as it will indicate if reprojection is off, on but limited by GPU, on but limited by CPU or not required as you are at 90fps+

I am finding Motion Smoothing to be pretty good with the G2.

[Rocky49]

I'm running at 66% of 100% and also went back and turned off the forced Reprojection.  I get Framerates in the 60s, 70s in all maps except Syria when not on the ground taxiing etc. If I stay in the forced mode I am held at 45.  Anybody else having issues with the Syria map?

Ok, here is what I have in my steam car cliff home. You can see it’s not what is shown in the video and I don’t have the options to bring up that screen in the video.

Ok, firstly, I think we should take this back to your other thread on this as we are getting way OT.

However,  firstly, you are still not in SteamVR dashboard as shown in the MS video. Your are showing screenshots from SteamVR Home. Not the same thing. To get to the dashboard settings, you have to press the G2 right controller's system button (the one next to the windows button). Then you will see the screen shown in the video.  From there, access the WMR tab on the bottom left. Please read that linked to document. It is very helpful.

A couple of other things. There is no need to have SteamVR Home loading . You can switch it off in the SteamVR dashboard.

Also, I'm not sure from your screenshots, but it looks like you are running at a General 48% SS as well as an app-specific 48%.  As they have a multiplying effect, that would give you a horribly low rendered res.  The default res for the G2 is 100%, approx 3100x3100.

If you are having all these issues with 60Hz, low res, etc. on your hardware, then, as I've said to you before, there is something wrong.

[markturner1960]

ok, back to other thread, apologies OP.....

Absolutely mate, was just adding some input from the guys who built the headset. To my eyes, and I think that's important because everyone's eyes are different, I see a massive difference in clarity between 54% and 100%. The hornet MFDs are a blurry mess at 54% (without leaning in like I had to on the Rift S), but at 100% I can read them from the normal seated position.

 

With my 2080 I am never going to hit 90fps without turning everything down to minimum, so I'm working with settings that give me a stable 50fps so that reprojection can do its magic.

 

Will be a different story when I get my 3080, at which point I will definitely try your settings.

 

They really have made it confusing in Steam VR SS settings.

 

The first setting is a global percentage. The second allows you to set for each specific game. However, unlike most settings where the game specific setting would override the global setting, the steam SS settings are actually multiplied, so:

 

Steam SS = Global Steam SS x Game specific SS

 

If you set global to 54% and game specific to 120% then you will get an actual SS setting of 65%

 

What the reddit article is saying is that the G2 was designed to need a certain amount of SS for optimal clarity, and that SS happens to be the 100% setting. I guess that makes sense then as to why 100% is the default value!

I am sorry to bring this back, been re reading this thread and others, but am still not clear. To get the 100% SS as recommended by HP, that 100% figure is the end result figure derived from home x per app (IE 54 x 120 =65 in the above example, means I am running at less than the optimal 100% ?)    54 x 200 ( which I have set currently) = 108% just over optimal.....

 

above, you are talking about the difference between 54 & 100 % - again are you referring to the final multiplied value, or one of th two multipliers?
