Problem with high-resolution rendering on M3 Ultra with 512GB unified memory

[bimterresheim]

Hello,
I'm experiencing an issue with my new M3 Ultra that has 512GB unified memory. I purchased this powerful machine hoping to use "render to file" at high resolutions directly. However, whenever I try to use "render to file" at a quality level of 5 or higher, I immediately get the error message: "[FBO] Initialization failed! (not enough memory?)"
Is there a way to adjust OpenGL settings somewhere to fix this issue?

Nope, the limiting factor here is probably the GPU memory.
