As stated further up already, is still experimental and needs further testing - and now also fixing apprently - from someone from the community who’s a coder and has a recent NVIDIA board. I’ll do the best I can to find out what is causing , but without a recent NVIDIA board, I’m currently limited to looking at plain code. Since I did the time consuming part of porting and merging already, it should be comparably straightforward for someone with some engine experience and capable hardware to fix it. Until someone like that pops up and does it - or I find a way to get a recent board somehow, you should consider VXGI port not ready for anything yet. Sorry for that.
