**What’s the no-fma dll? Which one do I need?**
|
||||||
|
|
||||||
|
There are two Windows builds of the plugin, one for CPUs that support
|
||||||
|
[FMA instructions](https://en.wikipedia.org/wiki/FMA_instruction_set) and one for those that don’t.
|
||||||
|
If your CPU is a Haswell (for Intel) or Piledriver (for AMD) or newer,
|
||||||
|
you can use the regular version (which is about 20% faster).
|
||||||
|
Otherwise, grab no-fma.
|
||||||
|
The Linux build uses fma instructions.
|
||||||
|
I trust that if you’re a Linux user on older hardware,
|
||||||
|
you know how to compile your own binaries.

about not wanting to reimplement

when we already have a working grain filter.

something that already exists.
