Does anyone know if there's a proper name for anti-aliased pixel art scaling? I don't mean xRB / hq#x / MMPX. I mean the equivalent of integer scaling pixel art and down scaling via bilinear.
Maybe "super sampled nearest neighbor scaling"?

But, doesn't actually need to be super sampled. It feels like there should be a proper name for it, and maybe there is and it's just been appropriated by what people call pixel art scaling algos.

The "anti-aliased" example looks blurry and bad when zoomed in, but looks great when displayed at the real resolution. For example this is how Shovel Knight does its scaling, and no one complains about that game.

I implemented a couple of different approaches to reconstruct normals from a depth texture. No separate script dependencies, and works for Unity's built in and URP as a post process or on world objects.

No script dependencies comes from @_kzr 's latest version of his inverse projection setup, which oddly still uses a script to setup an inverse view matrix Unity already provides by default.

"Improved" method based on János Turánszki's Improved Normal Reconstruction with some minor optimizations. Works surprisingly well for getting rid of depth disparity artifacts, but adds others on interior edges.

@IRCSS @benoitvimont @Atrix256 I use blue noise temporal dithering with A2C. Been meaning to post a tutorial on it at some point.

_MSAAQuality and _BlueNoise64Tex are set via a c# script, with the blue noise texture being swapped each frame.
@IRCSS @benoitvimont @Atrix256 That's the dithering code used to produce these examples:
@IRCSS @benoitvimont @Atrix256 This is the code I used for converting from a dithered alpha to explicit coverage mask (either SV_Coverage or gl_SampleMask).

I want to rant a bit about recent price & spec reveal of the Samsung Odyssey G9, and why this it is an impressive bit of tech ... and how Samsung is lying by omission.

samsung.com/us/computing/m…
Basic specs their web site (and all the press dutifully copy paste everywhere):
1000R 49” 5120x1440 HDR1000 QLED 1ms 240hz with GSync and FreeSync Premium Pro support. This has all the bells and whistles you could ever hope for. Except there’s one more spec that’s important.

Weird new @unity3d bug I think I found. For the last few months I've had strange bugs with my builds that no one else on my team experiences. Totally clean projects will fail to build when using Build & Run, succeed when using Build, but may have crash at consistent points.
@unity3d I didn't really think much of it. They started happening on a single new platform that I was having other issues with, so I figured it was something with my dev environment for that platform that's broken.

Just started working on a new platform ... and I have the same issues.
@unity3d Both platforms error when doing Build & Run, and both errors are something deep inside Unity's c++ code, and are different errors. However, both were occurring inside sound related systems (one complained about the DSP not being available, the other that FMOD had no device).

We shipped Planetary Annihilation on Win, Mac, and Linux. Linux uses we're a big vocal part of the Kickstarter and forums.

In the end they accounted for <0.1% of sales but >20% of auto reported crashes and support tickets (most gfx driver related).

Would totally skip Linux.
So yes, fragmentation is still totally an issue.
We eventually laid out a guide with known good versions of Linux and graphics drivers, but it didn't matter. Part of the allure of Linux is the customizability, so few actually stuck to it, and generally wanted to run the game on older hardware we didn't support.
