production render not pegging cards to 100% usage

[s_gru]

just recently put new cards in my machine. i'm not getting 100% pegged usage during the render. i also recently updated to v6 update 1. i remember this seemed to be an issue with IPR? but with my old cards, i'd see 100% on production rendering. my driver version for both cards is 531.41. they are not OC'd at all.

Your new machine is fine s_gru
Having the usage graph like this is expected, with current and old V-Ray GPU builds. Keep in mind 4080 is a lot different than 1080

Use the least amount of render elements, and stick to progressive sampler type. This is going to help improve your GPU utilization
On another note we are aware of this behavior on high-end GPUs, it could be improved for sure(it is big part of the GPU roadmap). Still you should see a massive performance improvement going from 1080 to 4080, at least 4x faster renders

Best,
Muhammed

yes i'm only doing 2 4080 vs 4 1080s and something are a lot faster some things are about 2x as fast. RTX vray benchmark is 6x faster! right now i'm doing an anim with nvidia upscale output res 1080p and i'm getting about 1min +- per frame which is really cool. having major issues in vantage that i need to post about.
