Light Baking Performance

[trey.coursey]

I have a question about light baking.  I have two Geforce 1080 ti's that are not SLI.  When baking my system shows only about 40% of GPU 1 being used.

Will I get any performance gain by hooking the two cards up in SLI?
Are there performance bottlenecks that can be optimized to use more of the GPU in future development?

Thanks.

Sorry for late response Trey, I had to check with our tech artists.

Light baking relies on GPU, but depending on a scene CPU can limit its speed.

You mentioned that light baking utilizes only 40% of GPU, so SLI wouldn't give you anything in terms of performance.

Yes, we have some thoughts on improving the light baking algorithm, this is the thing that definitely should be done.

Thanks!

New generation of Nvidia cards have support for raytraycing. It this something, which could be used for speeding up baking, could be your algorithm modified to support this?

RTX offers real-time ray tracing, so it's not similar to Voxel Probe technique. 

Light Baking optimizations I mentioned above have nothing to do with the latest Nvidia GPUs :)

Thanks.
