hi it works in previous version for me but not in latest - says dx12 not on when it is - anyhelp - is it just not working in this version yet?
Hi ,
Are you using a an NVIDIA GeForce GTX 10-series or Quadro P-series graphics card? If so, support for Path Tracer for these graphics cards, which used software-emulated raytracing rather than hardware-accelerated raytracing, was removed from Unreal Engine 5 and 5.1, and since Twinmotion now runs on Unreal Engine 5.1 in Twinmotion 2023.1, then this means Path Tracer is no longer usable for these graphics cards going forward. If you want to use Path Tracer in Twinmotion 2023.1 or later, you will need an NVIDIA RTX graphics card or an AMD Radeon RX 6000 series or newer.
Path Tracer will still work for older NVIDIA cards in Twinmotion 2022, so you can continue using Path Tracer in these versions without upgrading.
Best,
Raghib
ahhh that will be it - another nail in the old hardware coffin - thanks for letting me know
