Question / Help Quasi antialiasing - that works!

[Budkovsky]

I'd like to share you the way I discovered how to improve quality of the 3D games streaming/recording.

As far as I know OBS doesn't support antialiasing, so some games look a bit poor.
A few days ago I tried to resolve this problem using upscaling and downscaling with filtering.

What did I do?
Scenes -> Sources -> Game Capture -> Scallng/Aspect Ratio filter -> resolution 1.5x bigger than the source
Settings -> Video -> Base Resolution as defined in scaling filter and Output Resolution as the real game's resolution

In my case I capture game in 1920x1080, so my values are:
Game Capture -> Scallng/Aspect Ratio filter -> resolution: 2880x1620 (bilinear or bicubic filtering)
Settings -> Video -> base resolution: 2880x1620, output resolution 1920x1080 (again bilinear or bicubic filtering)

And that works, no poor aliasing egdes in my stream.
Videos are nice and smooth, a bit blurry but the final quality in much better in my opinion.
You can change the setting of filtering methods(bilinear, bicubic, lanczos) to get more smooth or sharpen result.

I spent a lot of time seeking antialiasing solution for OBS and didn't found anything similar.
If I'm wrong and this is nothing new for OBS users, delete this post please :-)

Bro you are gold! hope its not gonna eat up fps or smth...but it worked! Tryin to get around fxaa not working in obs capture but workin in my games since ages.I prefer fxaa whenever i can get rid of temporal AA. It's actually making the video capture just a tiny bit softer, enough to not make video pixelated because too sharp. insane! This should be pinned!
