# Xformers
Xformers library is an optional way to speedup your image generation.
There are no binaries for Windows except for one specific configuration, but you can build it yourself.
This optimization is only available for nvidia gpus, it speeds up image generation and lowers vram usage at the cost of producing [non-deterministic](https://github.com/AUTOMATIC1111/stable-diffusion-webui/discussions/2705#discussioncomment-4024378) results.
A guide from an anonymous user, although I think it is for building on Linux:
If you use a Pascal, Turing, Ampere, Lovelace or Hopper card with Python 3.10, you shouldn't need to build manually. Just launch the repo with `--xformers`. A compatible wheel will be installed.

### If you use a Pascal, Turing, Ampere, Lovelace or Hopper card with Python 3.10, you shouldn't need to build manually anymore. Uninstall your existing xformers and launch the repo with `--xformers`. A compatible wheel will be installed.
