No, it's not nVidia-only. ATI supports it as well.

As far as I know (pls correct me if I am wrong) all extensions with _EXT are multi-vendor.
Nvidia specific extensions are marked with _NV and ATI specific ones are marked with _ATI.

Just a precision, EXT multi vendor does not mean that both ATI and NVIDIA actually implement them ... but they can.

If it crashes you are doing something wrong. On my ATI card compression works like a charm.
