I am rendering 4k on a Ryzen 3990. ~1500 frames (10 cameras).
1 HDRI is the only light source, lots of proxies.
Very small camera movement only, no animation, the content is essentially the same on each frame.
Im using a noise tolerance (7%) and denoising (90).
I see a few seconds added to each frame time. Not the first time this has happened, but this project will go to a commercial farm (Rebus) and I dont want to burn my credit unnecessarily. If I suspend the render then restart it on Backburner, the frame time drops to the original frame time and begins its creep up again, frame by frame. After 35 frames it is +50% over frame 2.
Ive added some images below to describe the problem.
Any help much appreciated.
Bump.
Has no-one else had this issue? Its happened on the last 3 projects I rendered frame sequences for, really need to find a working solution…
Thanks,
Tom.
I had this once during a big project I recall. We had something like a memory leak where each new frame would use more ram and slow down the render. Unfortunately we didn’t solve it at the time because of deadlines and it was a minor issue.
Would love to hear a solution though.
