and here comes the 3D nostalgia
You can do that in any 3d engine, it's a matter of the texture settings once you have the models and textures.
Lol the next gen in nostalgiaQuote:

Do you really want to disable that? I think you're better off passing on that one (and even software renderers on PC were already implementing it, even if to some limited extent - Quake is known for this, and I don't recall either The House Of The Head nor Carmageddon II distorting despite me running those in software mode either). Also Saturn is much less affected by it than the PS1, and the N64 implements it as well...
But yeah, it boils down to this basically:
- Use a low resolution. A pixel density akin to 240p will do
- Don't use texture filtering
- Don't use antialiasing (d'oh)
- Lo-poly models and lo-res textures =P
A better question is whether you can find a modern engine that doesn't hog all the system resources and some more just to display a cube.
EDIT: being more specific.
Also something in common is that those used 15-bit (not even 16-bit) color... that will be harder to do since hardware doesn't support it anymore. I suppose you could fake it using a postprocessing shader (render everything as 32-bit, then use the shader to intentionally reduce color resolution - include dithering here if you want to look like PS1, don't if you want to look like Saturn).
For 1080p and above I actually prefer to turn off antiliasing.Quote:

Render the viewport to a small render target (320x240) and draw that to a full-screen native res quad without any texture filtering, and use a colour lookup shader (e.g.: http://gamedev.stackexchange.com/que...ette-in-opengl).
Sounds intriguing!Quote:

That's how we get retro-looking games that take 70GB disk space and require GTX 1080 minimum :P (why yes it's one of my pet peeves, can you tell?)Quote:

The idea of using modern game engines to simulate 1995 3D is really amusing. It's almost as bad as a Magic The Gathering life counter on the play store written in Unity. Never have two buttons and a number counter destroyed battery life so quickly. At least the MTG life counter thingy is rendering more than 320x240 pixels.Quote:

They can be reconfigured to be much nicer on the hardware, but by the point you do that you've spent so much effort that you may have as well made your own engine (which would be probably much more lightweight).
Actually I lie, I recall Godot spending much less resources than other engines (since they focused on optimizing what's already there before adding new features, that's why the 3D seemingly lags behind compared to other engines). I'd really need to check though, I haven't done any real tests on it.
^It's not an overkill... in fact it's much much muuuch easier to do this over an "AAA" game...
"Jaggy PSX effect" is actually achieved by randomly modifying the vertex positions in the mesh on the fly, either based on shader's local vertex coordinates or object's global coordinates corresponding to the camera. This can be done in any modern game engine.. there are a plenty of examples for Unity if u google it. and it will even run on a Mobile.. so it's pretty much optimised AF.
p.s. of course u'll need lowpoly models(or so called LOD system to downsample highpoly ones for you again on the fly), 16-bit gamma dithering on textures(unlit textures) and fake shadow projectors. All can be done easily in Unity.
