I just need to ask NVIDIA a driver related question.
You see I’m working on a Portal RTX mod for GTX users and I was wondering why ray_query support was dropped from the GTX line after 460.89, it makes it hard to develop for an old driver and I think it would had made more sense to keep it then to remove it
Hi there @KingVulpes,
I am curious, how are you planning to do a Portal RTX mod for people who do not have an RTX GPU? Are you planning to use SW emulation for the path-tracing parts? Or shader magic?
As for ray_query in older drivers, reasons for decisions on API deprecation is usually not made public. But it is safe to assume it had real-life technical reasons. In this case my guess would be because ray-tracing is not supported (in HW) on GTX GPUs in any case. And since these are legacy driver branches it is really unlikely that things are re-introduced to them. I am sorry.
I am not that familiar with Remix as such and the NVIDIA engineers who are, are not regularly reading these forums as far as I am aware.
I saw you already have a lively discussion going on on the Remix Discord, which I would have recommended. Our NVIDIA representatives are available there, you should be able to tag them just in case.
And you probably also know about the “Issues” section on the Remix Github. Another place to get more info.
Thanks!
Thank you 👍, and yes the mod will be forcing SW emulation for pathtracing, Remix already accepted the 16 series, there’s just lots of bugs with it
