Ray Tracing

[TheSiameseDreamer]

It's sad to see no plans for ray tracing.

U want 50% less FPS?
To me it seems it uses shadows(partially) and at least RTGI(Lumen)...

Edit. Also RTX will strangle the perf of nvidia 8GB cards by requirering extra 1.5GB VRAM, bringing 8GB Vram usage to over 10GB in some games.

So in top of "uNopTimIzAsIoN" u will have 35-50% less FPS and major stutter due to VRAM usage and/or texture loading issues.

Why is it sad? it's pointless and does nothing for the game.

in games i cant tell difference at the time of playing

If you have an 8gb card you shouldn't be using ray tracing anyway. Your point is moot as well. The feature should be there for those that want to and can use it.

[WHY SO SERIOUS???]

the devs should add hardware lumens at least, the game looks like crap now

It has many visual issues, I agree.

It's sad to see that devs prefer to add squirrels instead of fixes :>

I saw a squirrel today in the red forest. Not sure what it's supposed to add to the gameplay... utterly insignificant

This game already has some basic raytracing, thats what lumen is.

For some reason when I first start the game after installing it, reflections are very blurry and pixely but seem to get better as time goes on, maybe shaders still being compiled or something, or maybe its tied into performance.

RTX is way more stable than lumen, when done properly, but implementing RTX themselves over using unreals version would be a huge undertaking though.

Whether you use Lumen with hardware acceleration or not, Lumen is based on ray tracing. Software mode uses signed distance fields (SDF) to find intersections along a ray and so called cards to store lighting on geometry. Hardware accelerated ray tracing finds intersection using triangle-based geometry, which can be more precise if the original geometry also is made out of triangles.

You might find this interesting: "https://knarkowicz.wordpress.com/2022/08/18/journey-to-lumen/", the history of Lumen. I would imagine that a lot of optimization was required, they use a LOD system as an example.

quote from the article.

When we started Lumen, hardware ray tracing was announced, but there were no GPUs supporting it, nor any concrete performance numbers. Current console generation was clearly coming to its end and next-gen consoles were just around the corner, but we had no idea how fast hardware ray tracing is going to be or if it’s even going to be supported on consoles. This forced us to first look for a practical software ray tracing approach, which later also proved to be a great tool for scaling down or supporting scenes with lots of overlapping instances, which isn’t well handled by a fixed two level BVH.

Tracing in software opens a possibility to use a wild variety of tracing structures like triangles, distance fields, surfels or heightfields. We discarded triangles as it was clear that we won’t be able to beat a hardware solution at its own game. We briefly looked into surfels, but those require a quite high density to be able to represent geometry and updating or tracing so many surfels is quite expensive.

There is not ray tracing in UE5, it's Lumens and they need, firstly, to make them hardware and not software.

This game is a mess, bought it and didn't even started it, every single time I read forums I find peopel with new severe issue... gonna wait a bit again :(

Lol. Perfect comment.

I hope devs will see this.

Didnt see the 8GB 5060ti review, dont know if Lumen is RT or not but likes to just complain about the game bc its popular in YT videos, got it.

Replacing the sh1tty UE5 Lumen with hardware implementation may be for good eventuality. Unless they mess it up like everything else. lol
