You should find that clarity without reprojection may be better as well, it makes it all fuzzy for me when it's on.

Yeah it’s opposite on my end. 

[Burt]

Yuck !!!  I I'm not one of the lucky ones ! back 90hz for sure. 

[edmuss]

I can use 60Hz and bask in the refresh rate glory but if late I've been finding it's making my eyes tired quicker, but then I have been burning the candle at both ends and living on 6 hours sleep for the last few months!

[Burt]

Well your helping a lot of us on either end so I appreciate it. Please get some rest ! 

[Jon Fenton]

Has anyone got any steer towards getting the mask edited and how to go about it? (if indeed that is what is causing my problem?).

Ive got everything else set up and tweaked to optimum, but just this breakthrough around the very extreme periphery of my headset image is annoying the hell out of me that I can't seem to find how to eliminate it.

 

I'm just using the fixed presets for foveated rendering (not customised them), and so hence why I am more inclined to think it is a VR mask issue rather than that - but open to all/any advice.

 

Many thanks

I was watching this earlier today. Go to around 22:40 maybe this will help. It’s a msfs video but was interesting how this worked.

Thanks. Burt, but this is not the problem.  I understand the foveated rendering.  This is not a resolution issue or artifacting, but rather as if the mask that sizes the image to the lenses is the wrong size and so a tiny bit of an alternative image is peeking through on the very bottom edge of the in-headset view on each eye.  It is most obvious when flying above a brightly lit cloud layer and when I lift the headset to look at the 2d mirror, I note that ouside of the mask shapes is indeed bright white cloud image.....I think this is what is showing on the lenses and therefore suspect that there is a measurement wrong somewhere.

I've never needed to set a custom mask for running opencomposite, perhaps @nikoel might be able to offer more insight as I believe he played around with them

[M1Combat]

Yeah there is a way to adjust that mask but I don't recall how as I've not needed to do it myself either.

I would search this forum for something like "VR Mask edit" or something like that.  You'll find it.  Someone wrote a how-to as I recall.

[_Hoss]

Look on Youtube as well.

 

[slughead]

I've never needed to do anything with the mask either.

[Jon Fenton]

Thanks guys.

 

I was more after if anyone could confirm that this was indeed the cause of what I seem to be experiencing before I started fiddling with files and values therein, but I have indeed found the videos explaining how to remove the mask completely.  I will try this and see if it makes a difference.

 

edit: It was indeed the cause - Speed of Heat had confirmed it in another thread that, when not using MSAA, the mask is not black in colour and so any mismatch in the periphery shows up.  Solution is to either use MSAA or reduce mask size slightly.  Thanks SoH!

 

Perhaps ED can change mask colour to black when also not using MSAA in the future.

Good Morning

I have a question about Msi Afterburner not displaying with OXR. Before I made the switch to OXR “last weekend”  I was experimenting with gpu undervolting and would start a mission with my G2 off my head and read the values on the monitor in the VR window. Well I noticed last night the msi/af wasn’t displaying so is there an issue that oxr is not letting this to happen? And is there something I have to do to use msi/af like I did with SVR?

Thanks

I have a question about the "Shaking Reduction" setting on the Input tab. For whatever reason, it won't allow me to change it. On the OpenXR Quickstart page, it refers to "Shaking reduction, formerly Prediction dampening (only when supported by the system) . . ."

What about my system wouldn't support the feature? What do I need to add?

My sytem: i512400 // RTX 3070ti // 32G DDR4 // Reverb G2

[edmuss]

Should work fine, it happens that it needs to be set to a negative number though not positive so try altering the setting in the opposite direction that you think you should!

It helps a bit particularly with stabilising helmet mounted sights but I understand that it can cause increased artifacting if motion reprojection is enabled.

[edmuss]

Edited the first post regarding running FSR >100% with positive results and better perceived image quality than <100%.

[Burt]

Thanks for the update I’m gonna give it a try. It’s been a couple of weeks now and everything is running okay but I feel that somewhere-somehow I can get alittle bit more clarity in the cockpit …just alittle bit.

Using the upscaler shouldn't increase clarity but it will improve performance.  With the G2@3160 wide and FSR 150% with no sharpening I can still read all of the dials in the A10 without having to lean forward, it's just a little crisper without the upscaling.

It might be purely placebo on my behalf (the difference between image quality with negative/postive upscaling ratio) so try it out yourself.  It's quite possible that the code has been modified/improved since I started this thread

[speed-of-heat]

I do get a frame rate increase (you are driving less pixels) but i don't get an improvement in visual clarity indeed a nasty shimmer is introduced 

it is also less clear, at least for me , in the 18 i have to lean forward slightly to read writing clearly 

 

with a G2 at 3160 and FSR 150

and zero sharpening

I saw the same. That shimmer... ew.

[edmuss]

Indeed the shimmer is still present (I think it's unavoidable in DCS currently when upscaling) but is there equal shimmer /performance gain when scaling above the 100% rather than below to achieve the same pixel density?

Logically if you're driving the same number of pixels either way then the output should be the same, but then what DCS does isn't always logical

I do seem to have seen an improvement in the shimmer by using the upper ratios though, again it could just be placebo?

wait a minute ...

maybe if have misunderstood you? 

my custom render scale is set at 100, in OXRT, which gives me an in game resolution of 3160(something) ... when I set FSR to 150, that drops the resolution to 2100(something) meaning I am driving (generating less pixels) which FSR then upscales to 3160, which is how we get the performance uplift ...  as the additional pixels (gap) are rendered synthetically (which is what causes the shimmer) ...  the only way to render the same number of pixels would be to increase the render target and then run FSR at 150...? 

 

[edmuss]

No I meant running 3160 resolution and FSR 68% (I think it's about 68 to achieve the 2160 ish render target) vs FSR 150%.

Neither are going to be shimmer free but I've felt that it's lessened by using 150 vs 68.

 

[speed-of-heat]

OK I havent tried FSR at 68% I will have a go later today if i get a few and compare and contrast to 150%

[Digitalvole]

Please forgive my ignorance, I’m new to OpenXR.

When I first tried it I was blown away by the quality of the image, then I turned on motion smoothing and a single tear rolled down my cheek. It went from jaw dropping beauty to kind of washed out and blurry.

On the plus side I was able to fly over the Mariana’s for the first time and down low over Dover without getting a judder induced headache. So I think I’ll stick with it, I’m just curious as to why does turning on motion smoothing effect the clarity of the image so dramatically? This isn’t the case with SVR or the Oculus software is it?
