Specific scenarios that benefit from RTX acceleration

[GregCooper]

I'm curious if anyone with RTX cards has done any testing yet comparing speeds? Would love to hear any impressions. I've read the CG blog post broadly outlining the areas that do and don't see a benefit. I'm curious about specific scenarios though, for example:
- would a scene that has a lot of reflection and refraction benefit from RTX? Does this fall under ray casting or shading? I'd assume this would be mostly ray casting.
- will SSS materials render faster?
- Hair- Xgen & Vray fur?
- Volumetrics? environment fog and phoenix sims etc

I'm currently using Pascal gen GPUs - 1080tis, considering upgrading to some RTX cards at some point.

Yeah I’ve already seen that post but thanks. I’m more thinking specific scenes designed to test some of the scenarios mentioned in my previous post

Generally it has to do with geometry; scenes with lots of objects and instances, forest pack, hair and/or fur seem to get the biggest speed boost.

Interior scenes specifically benefit massively from RTX, It is always over 50% speedup
I have tested 3 scenes so far, one was nearly 80% faster with RTX and 2 others were 50-60% faster
Other scenes that use a simple HDRI for lighting is around 30% faster with RTX,
For what I do the update has been game changing, and I didn't expect that honestly considering how RTX was kind of scam for gaming
VRAM usage with RTX is 15 to 20% higher though, and I wish this could be improved in future

Cool thanks guys that’s helpful
