Anti Aliasing managment in DCS

[PeevishMonkey]

Hi.

Is anybody knows, how it words now in current version of DCS on NVidia video cards? (After MT relesed)

For DCS's native SSAA I've already known - it doesn't work.

The most interest - what about Anti-aliasing: Transparency  (NVidia users have this options in NVCP). What is the best way to use it?

Grab yourself nvidia Profile Inspector https://github.com/Orbmu2k/nvidiaProfileInspector/releases/download/2.4.0.4/nvidiaProfileInspector.zip and choose Sparse Grid SSAA as shown highlighted in pic below, it provides superior image quality over standard Super Sampling - be sure to match the SGSSAA amount to the MSAA amount in DCS for it to work properly.

4x SSAA ?! Are you okay man that's at least 8K for a 1080p screen, man I feel bad for your VRAM usage

Don't forget that we are talking about "transparancy AA". It's not equal to general SSAA.

Oh yeah you got a point, but it's still supersampling, I did some research it's made to improve MSAA, it's a hit or miss feature and was first a bug that was kept...
Tho I think this will harm FPS and maybe VRAM usage, since MSAA on deffered rendering uses a lot of VRAM and VRAM bandwidth.

For the people who are curious is the two main good links that explain the thing properly and clearly :

Yes. That is hope "Multi Sampling" for transparancy will be my choice. I'm affraid, my 3070 is not the best for other options...

Do you mean Super Sampling for transparant textures in NVidia Control Panel is not the same as SGSSAA in nvidia Profile Inspector and  the last is better?

This dates back to the DirectX 9 days.  In game settings, set MSAA to x2.  In the Nvidia Control Panel, select AntiAliasing - Mode - Enhance the application setting, then set Antialiasing Setting to your choice, say 4x, then choose MultiSample or some value of supersample for Antialiasing -Transparency.  This tells the GPU, if you have a Mutlsampled buffer (MSAA x2 in game settings), then enhance it to MSAA x4 AND do multisample or supersampling on Transparent textures.  Transparent textures are things like HUD characters, labels, holes in chain link fences, etc.  You must have the Multisampled buffer activated in the game settings with some value of MSAA for this to work.  It would not work if you have MSAA OFF but SSAA ON in the game settings.

Then the same rules apply for MSAA and SSAA as applied to the transparent textures: SSAA is better, but expensive, MSAA is not as good, but very fast.

BTW, you do not have to increase the MSAA setting with Enhancement.  You can, for example, set MSAA 2x in Game settings, and set Enhancement to 2x in the NCP.  This allows you to get the transparent textures feature without increasing your MSAA.  I know some have said the NCP has no effect on the sim, but try setting Transparent Antialising to 8x Supersample, and watch your FPS drop.
