I have serious graphics performance issues with a new Lenovo X121e notebook that uses the E-450 APU.
- GNOME shell runs very sluggish. Often the framerate seems to dip down to ~10fps, for instance when switching between workspaces. That's no better than my old POS Intel Atom GMA950 netbook!
- I get only ~500fps in glxgears (not a benchmark, I know, but it still seems to be very slow).
- The game TORCS is not very demanding AFAIK, but still runs pretty badly at < 30fps.
- 2D performance is also noticeably worse than on the old Atom netbook (e.g. scrolling in a browser)
OpenGL is definitely accelerated, according to glxinfo, and I'm seeing the same on Ubuntu 12.04 (stock or with updated kernel/mesa/ddx, doesn't matter) and Fedora 17 (Live USB).
What the heck is going on?! The radeon drivers might not be as optimized as Intel's drivers, but this sort of performance is unacceptable. The GPU should be at least an order of magnitude faster than the old GMA950, but I see performance that is not actually better than this very old non-GPU.
