these are written down in every announcement I send for any Clutter release, and in the README file of Clutter: • OpenGL ≥ 1.2 + multi-texturing *or* OpenGL ≥ 1.3 anything else (shaders, FBOs, VBOs, etc.) is based on feature negotiation with the underlying platform, and Clutter tries to provide fallback wherever possible. > * Minimum Intel/ATI/nvidia chipset models with which a smooth > experience is guaranteed any intel integrated graphics card ≥ i915/945 (i.e. basically every card shipped in a netbook, except the GMA500). the 915 architecture was released nearly 5 years ago. the 8xx GPU series (and you can barely call them that) are not supported. > * Minimum CPU configuration for software rendering mode under swrast > and llvmpipe (useful for VMs) no, that's not useful *at* *all*. VMs should do a passthrough to the host GL implementation. if they can't, swrast is not going to cut it in any case. > In addition to letting people know where they stand in all this, it > would also help *us* make sure that GNOME Shell is usable (60+fps with > no background processes, ~30fps with heavy background CPU usage) on > the systems that we target.
