+On Windows, you will need the CUDA Toolkit and Visual Studio 2022. If you do not already have this, use `chocolatey`:

 If you have `xformers` installed, disable it, as it will be preferred over Sage Attention:
 
 ```shell
 comfyui --disable-xformers
 ```
 
-If you want to use **TorchCompileModel** to further improve performance, do not reserve VRAM:
-
-```shell
-comfyui --disable-xformers --reserve-vram=-1.0
-```
-
 Sage Attention is not compatible with Flux. It does not appear to be compatible with Mochi when using `torch.compile`
