Hello,
Just wondering if anyone has gotten Sparse Grid Anti-aliasing working with BH&H? I had it working fine with UE with my RTX 2070 Super, but can't seem to get it to work with BH&H using nVidia Inspector despite trying different combinations (Enhance, Override, Application Controlled, etc...)with anti-aliasing set to 2x in the game.

If anyone has it working with an nVidia card, if they wouldn't mind sharing their nVidia Inspector or card settings, I would greatly appreciate it. It's only SGSS that I can't get to work with the new version of the game.

Many thanks.

Sparse Grid Supersampling Anti-aliasing - A guide on what it does and how to use it in Skyrim (With Pictures)
So I searched r/skyrim and r/skyrimmods for the term SGSSAA and noticed there wasn't a post on it. So I decided to do a write up on what it is, and how to use it.

Note: This guide is for Nvidia cards only. As SGSSAA is designed by Nvidia.

To skip the boring crap and find out how to enable it, go to the bold text about half way down.

SGSSAA - What is it?
Sparse Grid Supersampling Anti-aliasing is a Nvidia developed form of Anti-aliasing that is actually a bug, but it was such a good bug that after much whining from the gaming crowd, Nvidia decided to keep it.

Now just to get some terminology out of the way, some of the acronyms on the internet can be confusing so here's a simple list to help.

MSAA - Multisampling Anti-Aliasing

SSAA - Supersampling Anti-Aliasing

TRMSAA - Transparency Multisampling Anti-Aliasing

TRSSAA - Transparency Supersampling Anti-Aliasing

SGSSAA - Sparse Grid Supersampling Anti-Aliasing

There are dozens of other types of AA. Some don't even have good documentation and some are discontinued.
How SGSSAA works is that unlike regular Transparency Supersampling that you find in the Nvidia Control Panel, SGSSAA is applied full scene, much like FXAA. Every pixel that passes is supersampled in a sparse grid.

The benefit of this is that it is better than 8x MSAA that is commonly used, is less performance draining than 8x MSAA, and is compatible DX9, DX10 and DX11.#.

How to use SGSSAA in Skyrim
You need a tool to enable SGSSAA, it's called Nvidia Inspector, and is available here: http://www.guru3d.com/files_details/nvidia_inspector_download.html

You can edit the settings yourself or download the preset here (SLI x2 here). Note that preset is set to 4x MSAA + 4x SGSSAA with AO, Vsync, Triple Buffering, and AF enabled. If the preset doesn't work, let me know.
Once done open it up and find the little tool icon in the middle-right, next to "Driver Version". A large window will open, in here you can edit nearly every advanced graphical setting for Nvidia cards.

In the search box (top-left corner) clear the text and type "elder", pick Skyrim from the list.

Once in it's now time for some editing, if you have the preset, you can import it using the little box with the down arrow in the top bar. I'm sure you can find it.

Working from top to bottom

Compatibility - Set "Antialiasing compatibility" to 0x000010C1

Antialiasing - Set "Behaviour Flags" to None, set "Mode" to Override any application setting, set "Setting" to 4x [4x Multisampling], set "Transparency Multisampling" to Disabled, set "Transparency Supersampling to 4x Sparse Grid Supersampling

The Antialiasing - Setting and Antialiasing - Transparency Supersampling can be set to any value, but they must match! 2x MSAA must have 2x SGSSAA and so on!

Set anything else to what you want.

Click Apply changes and it will save your settings.

Nvidia Control Panel will say "Custom" under Antialiasing - Transparency.

Now you're done! Here are some before and after images of just the main menu to show the difference.

As you can tell SSAA and SGSSAA must match the AA settings (2x or 4x or 8x, but all must match) to get SS or SG to work correctly.

I have been using 4x SGSSAA for years as my go to default in UE and PE. I don't have BH&HII yet so I cannot comment on its' usage in Sim. Thanks for the write up PR. I am now using MSAA x 4 in DCS and have found it to be the least FPS taxing and srtill give the best look for my RIG. I may now have to experiment with the combination of 4x MSAA + 4x SGSSAA. You have me curious now.

Or you can also try the NVIDIA SSAA tool in the WOFF\Toolbox folder, assuming it still works.

That is a good thought Pol. I used to use that little tool exclusively back in the day. For the record I don't see it in my ToolBox folder for either WOFF or WOTR though. I have it somewhere though and I will dig it out and give that a try as well.

The tool should be there we install it into the Toolbox folder in WOTR and WOFF for some years back now.
Maybe Anti Virus deleted it?

I normally set in-game AA at 2X, while in NVIspector:
AA mode: enhance application settings
Multisampling: 4x
SGSSAA: 4x

BTW the tool is still available on NVidia website
https://nvidia.custhelp.com/app/answers/detail/a_id/2624
The download link font is very tiny on my screen.

This file is identical to the one we have in \Toolbox folder.

Super thanks to everyone for their replies and advice.

I am finding that using the nVidia Inspector settings as Dornil posted seems to give me the best combination of performance and anti-aliasing quality. Still going to test some more and see if 8xQ MSAA and 8x SGSS will work good on my system.
