derek barker (lordodin) added a comment to D2383: Cycles: Add option to replace GI with AO approximation after certain amount of bounces.

I have been using this in production for a few weeks now and it is pretty amazing how fast it makes rendering interiors, There are also certain cases when you can use it for stylized renders but since there is no option to disable it on glossy or make glossy have more bounces it is near useless in those scenarios

derek barker (lordodin) added a comment to T50974: Normal map tangent computation is slow.

Are tangents supposed to be that slow? they are horribly slow with a decent sized scene 90% of the render is just computing tangents before the render.. well over 30 minutes in some of our cases. And then the real render (Post synchronization) takes like 2 minutes

Did you take a look at the release logs? We removed the experimental kernel and added SSS and CMJ to the official one, because we fixed the increased memory usage. Adding such features can always have a performance impact on the kernel, we have observed that with every major addition. (Motion Blur, Volume...).

@Greg Zaal (gregzaal): Thanks for testing this! Now they question is, why this solely happens on Windows and Linux is fine. If that is a driver issue or issue within the CUDA toolkit then there is not much we can do at this point. GPU development is already a challenge, and fighting internal driver / OS issues is out of our hands.

SLI is never ever on, The GPU was idling around ~300 MB before the render, after the render the memory climbed up to 1225MB of 3072MB cycles gave the error and reported it was using 1287MB which is more than the total usage on Nvidia inspector. Thats all I have for that certain situation I will see if I can eventually replicate it.

If you look at the image I linked I used a program to show how much memory was being used on the GPU so you can see the GPU only reaches 1225 MB of vram being used so it isnt that cycles is lying to us, it actually didnt make it to the GPU before it crashed.
