My VXGI 4.17.2 build is running terribly, from demos i saw this cannot be right. Its running at 5 FPS max when i check “Enable Diffuse Tracing”, my scene doesn’t even change.
My pc is low end but i didn’t expect to have this kind of performance at all, never get this with LPV.
we also need to know how big your scene is.
im running a 980ti with 4770k i7
i have a small room lit just by vxgi, it runs smooth as butter at 144 fps (first screenshot)
i also have a forest scene running vxgi and volumetric light from nvidia, if i crank up the settings it runs at 10 fps @Nocturness has a good scene to test vxgi over here: https://forums.unrealengine.com/deve…h-studio-setup
download that and see how it runs. post #4 has some console settings to use as well.
let us know how it runs for you
Edit: didnt see your post about 1 cube…not sure if its just your hardware or if something in the engine has gone wonky
