I am wondering if there is not something else going on with your hardware. I have a 3 years old i7 with intel GPU and a 2 years old one also, both of them are running both GL and software backend pretty smoothly and battery usage was actually lower than other compositor (especially in software). I must say I haven't done any benchmark recently as I didn't felt any behavior change. So maybe there is something else going on with your setup. Did you try to get a valgrind, oprofile or perf trace to see what's going on ? -- Cedric BAIL ------------------------------------------------------------------------------ Infragistics Professional Build stunning WinForms apps today!
