[Freesurfer] whether freesurfer version 7 still support GPU

External Email - Use Caution

Hello Freesurfer team

I checked the freesurfer version 7.0. It says that " but for now you should know that some features are not present in v7 (QDEC, GPU-capability, and recon-all -make)."

But from the hardware setup, it still needs Graphics card: 3D graphics card with its own graphics memory & accelerated OpenGL drivers.

This makes me confused. Since version 7 does not support GPU anymore, why does it still need the Graphic card? I found GPU may be helpful for some abnormal brain such as large ventricles. It may speed the calculation time. I do not know my observation is correct or not.

Thanks
