Indigo Renderer Forum

Hi all,
We have a new build of the benchmark out.
The last benchmark build was 4.0.64, so a long time ago. There have been a lot of changes in Indigo since then, including a lot of optimisations.

The most important changes for the benchmark are:

* Fixed performance scaling when rendering with multiple Nvidia GPU devices.

There was an issue when rendering with multiple Nvidia GPU devices at once, scaling wasn't nearly as good as it should have been. (see https://twitter.com/indigorenderer/stat ... 3650425856) This is fixed in Indigo 4.4.10.

* Enabled CPU bucket rendering for the benchmark.

Bucketed rendering for CPU was introduced in Indigo 4.4.5. It allows better scaling with many CPU cores, so it's perfect for benchmarking modern CPUs with lots of cores.

* Fixed issue with setting thread affinity when the number of CPUs in a group is 64.

This is quite a specific issue, but if you tried to render with exactly 64 logical CPU cores, thread affinity was set incorrectly.

Glad to see a new release :)

For the purposes of a benchmark, I think it's very important to throw away the first run: the optimised shaders have not been built, and the faster BVH only gets built after those I think? IMO the benchmark should do this, else many (most?) of the reported scores will be too low.

we take the speed of the last pass as the benchmark score, hopefully the optimised shaders and faster BVH will be done before that pass starts.

I think there are some people using essentially Celeron mining rigs, but yeah other than such odd systems it seems likely :) I gave it a quick run, seems to work well.

When is the Chinese version available？

I just ran my 1st test with Vii and Vega FE, scores are way higher now. (1st run all stock)

Edit: Did you guys make changes to the Bench Renderer or did driver improve or both?

- I'll run benchies on the old version later I guess.

Hi ghola235,

There were quite a lot of improvements and fixes for GPU rendering during 4.2 and 4.4, would be tricky to pinpoint what it was exactly.

At some point I will move the 4.0 results into a different section, as they can't really be compared to 4.4.

nice, I can see a big difference.

nice, waiting for rtx optimisations of indigo.
