CPU to do other work.
Yeung says DirectStorage offers multiple
tools for developers to maximize storage
performance: “by reducing
per-request NVMe overhead,
enabling batched many-at-a-
time parallel IO requests
which can be efficiently fed to
the GPU, and giving games
finer grain control over when
they get notified of IO request
completion instead of having
to react to every tiny IO
completion.”
Nvidia’s Huang said that
RTX IO offers “APIs for fast
loading and streaming directly
from SSD to GPU memory”and GPU lossless decompression. It’s unclear
yet whether that’s a special sauce, or just
Nvidia glomming onto the benefits of
DirectStorage itself. Nvidia’s marketing did a
