Comically bad performance

[seth_richardson]

These missed frames from 120 frame animation were the fails..... 30 minutes for 5 frames at 1080p. Charged 55 credits for the first render which took about 1 hour to render.

My machine these came from with a 4090 rendered the whole animation in under 30 minutes with each frame taking like 15 seconds. My question is why is this service so bad and second why am I being charged a ridiculous amount of credits for a render farm thats slower by a massive amount than a single GPU setup.

HI seth_richardson

Sorry about that, we will refund your credits.
The GPUs on the cloud are Tesla T4s, they are much slower than your RTX 4009 around 8x slower on average. they have 16 GB of GPU memory, which could be problematic if your scene gets close to the memory ceiling on the cloud. It is a known limitation of V-Ray GPU that rendering could be much slower, if you come close to the memory ceiling. How much GPU memory does your scene use?
Or could you please send me your scene to investigate?

The cloud could be useful if you have a large number of frames, it will assign a frame per GPU, but it doesn't do DR of a single frame on multiple GPUs

Seems like an odd choice to use gpu’s that perform worse. I did get an error on the farm saying they were out of memory which again seems wierd as the 4090 on my desktop wasn’t even using 10 gigs.

For a point of reference I recreated this animation for octane render. I shot it over to their RNDR network and not only was it cheaper by a large margin, but took about 10 minutes from upload to download.

Whatever your direction with gpu on chaos cloud is, I can tell you my experience was awful, slow and expensive. I think some serious work needs to be done there. Something is wrong.

I can send you the scene

seth_richardson Have you sent us the scene yet?
Is there a ticket number? or you can just use my Email

Thanks for the feedback, we use the T4 GPUs because of our cloud provider. There seems to be demand on high-end GPUs because of AI, they will be a lot more expensive to use.
I agree that they are way too old/slow at this point of time. I will take a look at the cloud very soon, to compare with high-end GPUs. I will compare with RNDR as well

Best,
