FAQ
Common questions
Which GPUs work?
NVIDIA RTX 20 or GTX 16 series or newer, with driver 572 or later and at least 4 GB of GPU memory. Some engines need more.
What about Mac?
Macs don’t need the pack. Apple Silicon Macs use one built-in engine build.
What about AMD or Intel graphics?
The GPU pack is NVIDIA only. On those PCs Musa runs on the CPU.
