Hello everyone,
I am trying to render a movie sequence in 4k x 4k pixel resolution. So far I got it running on my Windows Laptop with a RTX 2060 (about 8 GB VRAM). It just about works with the following settings with the Deferred Rendering Pipeline:
- Deactivated Temporal Anti-Aliasing
- Spatial Anti-Aliasing: 16
- High Resolution Tile count: 4 (this helped a lot)
I tried to render the same project with the exact same settings on an Arch Linux System with a RTX 4090 (3x as much VRAM as the RTX 2060, about 24 GB VRAM) but got out of memory exceptions. I found that the “Page to System Memory” option helped a bit but it still crashes after a few frames into rendering. Could this be a general issue from using Vulkan (Linux) vs. DirectX (Windows)?
If someone experienced similar issues with rendering on Linux vs. Windows and if they found some tricks to reduce the VRAM consumption, please let me know
