I recently upgraded to an NVIDIA GPU, previously I had an AMD one. Before, I would have Anti-Aliasing checked inside FSX (not from the CCC) and I thought it was perfect, inside the limits of MSAA, because polygon edges looked really smooth. After I placed my new NVIDIA GPU in, the internal Anti-Aliasing option was rendered useless because it just looks terrible, worse than 2x MSAA. So I decided to use NVIDIA Inspector for Anti-Aliasing, but I can't help but feel that even 8x MSAA doesn't look as good as internal Anti-Aliasing did with my AMD GPU.

 

Same case with Microsoft Flight. With my AMD GPU, I had AntialiasingQuality=4 (equivalent to Sharpness on High) and it looked just perfect. Now, even with AntialiasingQuality=16 (equivalent to Sharpness on Maximum), I'm still not getting the quality I did with AntialiasingQuality=4 on my AMD GPU.

 

This is driving me crazy, I upgraded to NVIDIA mainly because I thought I would be able to get more Anti-Aliasing options with NVIDIA Inspector, just to get worse results with FSX and Microsoft Flight. Internal Anti-Aliasing, which used to be perfect, is now useless, and I can't get the same results with NVIDIA Inspector. Has anyone had a similar experience?

I think you will find you will have to set some level

of sparse grid supersampling in NI to get decent visuals.

Are you running DX9 or DX10?

 

gb.

Set FSX to Anisotropic, and set AA on.

Make sure to start a default FSX profile with NVidia control panel using the Restore defaults function before using NI.

Use Transparency Antialiasing because the FSX screen is made up from smaller pictures with transparent backgrounds.

We can use the NVidea Control Panel and set Antialiasing Transparency to 2x, 4x or 8x, but problems come with certain planes sometimes looking jagged and instrument displays crumpled.

Instead we can set Sparse Grid Transparency AA using NVidia Inspector.

Here I have set 8x sparse grid, but first try 2x, then 4x. I'm also using 2 look ahead frames and vsync, FSX set to limited fps.

Thank you for the response. I'm running DX9.

 

I have already tried SGSSAA, but I can't say I'm pleased with it either. While it eliminates all the shimmering in the scene, the result on polygon edges isn't any different compared to MSAA, the performance hit is huge and I also get blurring of UI elements. I've also tried OGSSAA and HSAA but they don't seem any better. I've tried to look online but I haven't found any compatibility bit that improve the quality and eliminate UI blurring.

 

In general I'm just getting worse anti-aliasing after I switched to NVIDIA. With both FSX and Microsoft Flight things were perfectly fine with the in-game anti-aliasing, but now it's useless and I just can't get the same results with NVIDIA Inspector. Has anyone noticed a similar difference when switching from AMD to NVIDIA?

You posted this as I was posting the above. I'll try what you're saying, but are you sure that the behaviour flag you have on is right? In other games I've found that I can only get the result I want by setting it to "None".

>>In other games

 

maybe, but we are talking about FSX. Setup works for DX9 or DX10, and similarly for P3D.

I set up NVIDIA Inspector as you said, and while SGSSAA worked, eliminating the shimmering on the entire scene, the polygon edges still looked as terrible as before. It looks like using the internal anti-aliasing option is a no-go for me anymore.

Default fsx.cfg, try again.

Tried again with a clean fsx.cfg, but no change.

I can't see why yours would be any different to anyone else. There's something you overlooked.

In NVIDIA Inspector or somewhere else?

Can you post a shot of your polygon edges?

Caution, PNG images below. I've highlighted points of interest.

 

In-game AA, looks crap compared to when I had an AMD GPU: http://i.cubeupload.com/CzS9YL.png

 

8x MSAA from NVIDIA Inspector, looks better but still not as good as in-game AA used to be: http://i.cubeupload.com/YO61NY.png

 

I'd try CSAA, but it has been removed from Maxwell.

Both shots look odd though, especially around the tail number, or is that the paint used for the variation.

Since both shots are with MSAA, the tail number isn't getting anti-aliased at all.

 

So would you say that the anti-aliasing on polygon edges isn't what it should be?

Interessant...
