I have a Dell workstation and a Dell laptop. Both running FC5 with Xgl and compiz and it worked great ... Now I am running FC6 with aiglx and compiz and it seems to be requiring more resources to run. The more apps I open the poorer the performance (I know, Duh) but I did not have this problem with my previous setup and config. Anyone else notice this ... I have seen instances of higher cpu heat temps and I am wondering if these two issues coincide. James Dickson
