It means CUDA-accelerated binaries/recons on the GPU are no longer supported after freesurfer 6.0. I will make that clarification in the wiki page. Sorry for the confusion. Andrew

External Email - Use Caution Hello Dr. Hoopes
Does it mean that in Beta version 7, there is no GPU capability. But stable version 7 still support the existing GPU capacity.. Is it correct?

We still recommend this since freeview benefits from having a fast 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)."
https://surfer.nmr.mgh.harvard.edu/fswiki/dev7beta1
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
Frank
