@dburne, to be sure...The AA nvidia setting u refer to is Antialiasing-mode then Antialiasing- Setting    right?  not sure what the MFAA is about 

FWIW I tried using F16 instant action cold and dark ... opens with a long grass field which test the AA nicely.   With Nvidia forced at 8x ... nothing obvious happening and lots of shimmering.  With Nvidia off and DCS at 8x ... no shimering at all anymore.    Different for u??

 

 

Which map? I loaded up the Persian Gulf and it was mainly concrete ahead of me.

Ok so I loaded up the Caucasus Instant Action cold and dark, I assume that is likely what you are referring to. Looked pretty darn good to me, no shimmering closer to the plane, way off in distance a small amount but not enough to really bother me.

Antialiasing in NVCP does not work in DCS VR. Evidence... see below.

First image:  MSAA x2, NCVP AA application controlled, NVCP FXAA OFF as a baseline. Notice the HUD frame and the tops of hills.

Second image:  MSAA OFF, NVCP AA application controlled, NVCP FXAA OFF - noticed jagged edges of HUD frame and tops of hills.

Third image: MSAA OFF, NVCP AA Override Application, NVCP AA x8, NVCP FXAA OFF. No change compared to second image.

Fourth image: MSAA OFF, NVCP AA Override Application, NVCP AA x8, NVCP FXAA ON. No change compared to second image.

Tested with NVidia 4090 with HP Reverb G2 headset at native resolution and OpenXR. Screenshots taken from OpenXR Toolkit using screenshot facility.

That is correct.

Mode = Override any application settings.  Setting = 2X.

 

 

Could be I suppose anything is possible although I believe Supmua commented he did not see a difference either and he has an Aero. I was surprised  to see the results after trying it just for the heck of it but I am sure taking advantage of it and enjoying it for now.

 

 

I've seen similar settings in AMD Adrenaline control panel. Most of the same settings note that they only apply to DirectX 9.

Don't say that too loud my computer might hear you... 

Not that it matters but I do not run at any of those settings above, I already posted earlier how I was running mine. No skin off my bones gang, believe what you wish and run the game as you wish and I will do the same. In any event have a great day and enjoy I sure am! I would also note that I do not run Open XR for DCS, not that that matters either. I use Steam VR with my Aero for DCS. Never really found Open XR all that appealing with DCS - plus having to hack it in. Been a while though I may give another try at some point. Currently having fun not tweaking.

Hello,

Could you try MSAA x2 or + NVCP "Enhance the application settings" + NVCP FXAA ?

Thanks

Could you try it? Best to do so in a new thread dedicated to this as this topic is veering well off course from the original topic title.

Sure, actually I cannot retrieve an old thread about using FXAA in VR ( it worked .. ), should be better to retrieve this old thread instead to create another.

Today with DCS 2.8.5.40170 Open Beta - 18.05.2023 I made a comparsion between versions.

Same mission, just a single player F16 over Batumi.

To sum it up

2.7 : CPU 7.8 ms , GPU 8.1 ms

2.8.5 with Multithreading: CPU 4.6 ms , GPU 7.5 ms

Good job ED! It was woth the wait.

See the full test in the screenshot below with system specs. Running a Varjo Aero @ very high setting 37 PPD

Lets call the issue resolved
