Warning : Nun samples per thread reduced to 253363, rendering might be slower

[zach_ryder]

Why does this happen? The scene still rendered, just curios if it would have been faster. Not sure what this warning refers to.

Anybody know what this means?

[francomanko]

check your gpu ram usage, i usually got that when its using more ram than the gpu had

[zach_ryder]

what happens if it uses more ram than it has availble? It always ends up rendering

[francomanko]

it takes longer

Refer to this thread for an answer.

Just took a look at the thread hermit.crab. So is this something I should try to fix? I have a 3080 and only do interior scenes. Should I be concerned with the warning and get a gpu with more vram or just leave as is. I want to be able to render as fast as possible with my current gpu

[Luma3d]

Had a laptop with a 3080 and it ran out of vram regularly...purchased a egpu with 3090 and never had any issues again.

[zach_ryder]

Luma3d I've heard mixed revies on egpus but nothing specified for rendering. Is there any drawbacks on egpus in your opinion?

[Luma3d]

Nope...it allowed me to keep working on projects that the 3080 couldn't handle. The only thing that comes mind is that they are loud, but so was my MSI. TIP: Don't use MSI laptops...they suck. Had too many problems with it.

[zach_ryder]

Awesome, thanks for the tip
