Is there a way to simply force purge GPU ram?
Like a button somewhere in the interface?
(If not, it would be super cool to have one!!!)
I have a problem where, while working on 6k images, each time I press render, flame tells me that render time will be 25 minutes for 100 frames.
If I close flame, relaunch and press render again, render time falls to 5 minutes… arghh
I’m on a Linux box with poor P4000, on 2021.1 flame version.
Just one more clue.
On a render that says 25 minutes, if I render the batch in 2 parts.
First half of the setup then having the result of that render as a source for the second part, the render times are like 1 minute + 5 minutes…
I know the hardware P4000 is quite limited for 6k work but still, there is a problem with how Ram is filled and flushed during renders isn’t there?
@philobedo. Just wondering that when it says it will take 25mins, does it actually take 25mins? I had a situation similar where it said one thing ad did another. ie the render got to half way then boom it completed. My situation was also tlfx rendering not batch. might be very different(edited)
I have to say that I didn’t let the render go to the end of 25 minutes. But the average time for the 40 first frame was consistant with the complete estimation… and I was already at 10 minutes for these 40 first frames…
Did you try eciting the application and rerunning the render? It will clear the vram but you might fill it again once you look at the result view once you reliad your batch.
It would be great if we could toggle enable vram compression (as I think macs do) and get a lot more performance out of the available vram - it’s the most underspecced resource in the flames they give lowly freelancers like me
+1 for a simple button to flush the vram though
Yes, exiting flame is my workaround for now. But it’s obviously not ideal…
Yeah. That would be a good feature request to put out there.
I sometimes get a suspicious render time and I’m sure it doesn’t normally take that long. I like to think I am quite efficient and I usually have a 20 min threshold.
A quick exit and relaunch will fix it most of the time but I’ll vote up any feature that avoid that step of the process.
I’ll go and up vote. Do you have a number?
Addition of Vram flush button - Up voted
So to keep everyone up to date I had a feedback from Autodesk on that question.
To make it short, they’ve work on that already in the last without success so, only real solution is and will still be to restart flame when needed.
Second thing, Stephane reminded me that P4000 doesn’t meet anymore the minimum requirement needed for flame 2021, which is a 12GB GPU at least.
I’ll tell the facility I work in they have to put a little money on a RTX 8000…
