The linked post in the original comment at https://nickjanetakis.com/blog/gpu-memory-allocation-bugs-wi... has a lot of details.
AMD's GPU do use system memory seamlessly as a fallback, but NVIDIA's don't, at least not back in January 2026. Hundreds of people reported it in their forums too, or variations of the problem.
AMD GPUs use GTT seemlessly under linux. It looks funny in some "top" applications when iGPU that has 512mb allocated to it, uses 8gb of memory: displayed as "uses 8gb out of 0.5gb"
Thanks, I'll give it a read.
