Hey I’ve been playing with the latest VXGI for an hour or so and so far it’s fantastic! Shader compile times are much faster, having VXGI Voxelation enabled by default saves tons of time with converting projects, and the multi-bounce is working great. I do have one new concern however. Performance seems to have dropped since the previous release. Simple scenes that used to run with 30ms in fullscreen on my gtx 770 are now running with 35-36ms, with or without multi-bounce. When I say simple, I mean like the sample for the FPS template.

Edit: I just tried out the reflection subway scene, I’m getting 110ms in fullscreen on epic.

Edit2: VXGI doesn’t play well with stationary lights. Shadows are completely ignored for voxelation.

Edit3: Disabling static lighting and changing all lights to movable increases performance greatly.

I’ll bring up with the VXGI devs today.
