Lack of effective AA option in VR

[DeltaMike]

There's quite a bit less shimmering in OpenXR.

New VR  user Quest2 .

I've spent three days and nights reading and test study in VR  with DCS . It's an old game engine and is in need of big update from ground up . 

Please no more modules concentrate on fix game engine and AI . 

VR in other sims very good . 

I noticed my cockpit looks crystal clear, can read all gages but I look out side and it's jaggy and messy .

Objects are distorted. 

But 2D  @ 3200x1800 looks clear . 

Don't understand why VR in DCS looks so bad . 

My guess is old engine with VR  thrown in .

It desperately needs sorting....yes

More testing quest2 @ 1.2 and OTT 1.2 . ASW @ 30HZ . 

Half decent results . In single player.

It's now almost toward the end of 2022 and we still don't see lots of improvement for VR! bogey sometimes just disappeared within 4 miles just like how runway light disappered when you zoom out in DCS...

Just a quick update after 2.8 OB came out for anyone new to this AA technique in VR.

As @Mustang pointed out in another thread for nVidia users there's a very good opportunity to get rid most of the jaggies and shimmering if the hardware is strong enough by using MSAA 2x combined with SGSSAA (Sparse Grid SSAA) for transparent textures.

Check out my system specs in my signature.

The results are:

• the clouds became pretty nice at the edges (semi transparent parts are finely antialiased), athough the low LOD are still present for distance clouds at least on "Standard" clouds mode
• the transparent textures (power lines, fences, trees edges, painted lines on the tarmac) are very smooth
• the cockpit interior is extremely detailed, crisp and smooth (in particular to the HUD and MFDs symbology)
• in F2 view my plane is looking as good as never before, no jaggies, no shimmering, just pure joy
• no detectable fps drop compared to simple MSAA 2x

Important remark: be sure to make a profile with nVidia Profile Inspector for DCS only, so DO NOT CHANGE THE GLOBAL PROFILE, because doing it can mess up with other software display modes. For me changing the global profile wrecked up all Microsoft Office / Microsoft Store applications (immediate black screen after starting any of them), but disabling SGSSAA in the global profile again restored their normal behaviour.

overall i think for me performance isnt bad but shimmering is terrible to what it was, before i had next to none and now its everywhere and thats with all the same settings as before frame rates are good with very little stuttering but the anti alias thing is crappy.

Yup, i´m testing SGSSAA and noticed improvement in clarity first time i loaded the sim. I need further testing just to be sure it´s not placedo effect or something related but i don´t think so. Tested in Nevada and PF and performance and image was the best i had in a long time (although i have Terrain Shadows OFF for now due to issues with the new shadows, i usually use Flat Shadows but they are bugged), tested also in Caucasus but the performance was not so good, i need to investigate the culprit.

One more small extension: The SGSSAA can make the environment a bit softer. To encounter this, the following additional settings can be appied in nVidia Profile Inspector:

 

[4 - Texture Filtering]
Anisotropic filtering mode               User-defined / Off
Anisotropic filtering setting            16x
Texture filtering - Anisotropic filter optimization On
Texture filtering - Anisotropic sample optimization On
Texture filtering - Driver Controlled LOD Bias Off
Texture filtering - LOD Bias (DX)        -0.5000
Texture filtering - LOD Bias (OGL)       -0.5000
Texture filtering - Quality              High quality
Texture filtering - Trilinear optimization Off

 

Theoretically the negative LOD settings can force to use more detailed LODs for objects as the default, hence the softness is eliminated and also the cockpit interior would be even more crisp. Unfortunatelly this can make the shimmering a bit more in the environment, but not so much.

Personally I switched OFF the SGSAA because the small performance penalty, maybe I'll switch them back on if ED manage to iron out 2.8 or after implementing MT / Vulkan. But I really hope that in Vulkan they have the possibility to rethink the whole AA process to be as efficient as possible.

Yes something wrong with lighting and shading . Was like this when 2.5 hit DCS. 

Petro is struggling to lock targets again due to shaders and light condition.
