Nvidia's implementation of real-time ray-tracing isn't even available on DX11, so don't even bother thinking about that until they announce DX12 and/or Vulkan support. Would it benefit? As much as any game benefits by looking slightly more realistic. Personally, I'm not buying a thousand dollar card just so I can play a game that looks slightly better at 1080p60 or 2160p30.
Agreed... a very small percentage of people would be able to think about affording the hardware necessary to run such a thing. So unless someone finds a way to massively reduce the power required for ray tracing and can then run it on much more normal hardware, I don't even see this being considered.
Ray tracing requires Dx12 or Vulkan, which this game doesn't have, (although it may be getting one soon). I can't imagine it would make much of a difference anyway. And I believe the devs have mentioned that RTX development kits and licenses are quite expensive, and they don't really have the budget for one.
Just ask yourselves: how hard can it be? For a developer? For a team of developers? Well, the devs haven't talked about ray tracing that much, but I'm willing to bet we can get pbr in beamng. In 2019 even. Side note, I think we should make a gambling site for beamng updates. Like what comes next, new rendering stuff or a new map editor theme?
It's closer proprietary stuff, where as BeamNG attempts to be as open as possible, does not mix that well.
Ray Tracing, as advertised by Nvidia with the whole RTX thing, is a black box. Think it as GameWorks/PhysX and similar Nvidia tech. Although Ray Tracing itself is part of DirectX12 updates (DXR), which is not tied to a specific card brand. So yeah, beware of marketing strategies It's a rather new thing, and it's a quite niche thing as of now (and requires recent hardware) I would not expect this for BeamNG.drive.
