What exactly is the RTX/Raytracing being used for?

[mattihase]

While the game (for the most part) has some pretty snazzy visuals, I'm curious as to what bits of it are tied into RTX specifically?

To burn your GPU as fast as possible it seems.

Did the devs say something about ray tracing?

No, nothing. KSP2 does not use raytracing. Not sure where OP got the idea. Or maybe they're just asking if the game is using this and worded it poorly.

You aren’t kidding.  My 4090 runs at 100% almost constantly if Kerbin is in view.

Thats not a great metric for viewing the utilisation of a GPU, it doesn't give a great picture on what the GPU is doing.

Ok,

While I am facing Kerbin I am running at 100% GPU and 77 FPS with VRAM at 43%.

Turn and face into space and that drops to 63% GPU and goes up to 155 FPS.  VRAM is still at 43%.

Kerbin seems to be a vast GPU drain.

I think (read as know) people jumped the gun when the original system requirements were released and the started at the 20XX series cards. But there has never been any real indication that RTX specific hardware was required for the game nor that ray traced graphics were involved.

The specs also listed AMD cards, so, very confusing why people assumed an RTX card was necessary...
