I did install and run F@H about a year ago, only messed with it for two hours or so, abandon it for much the same reason, couldn't get it to play nice with BOINC. I would love to run it though, maybe someone here who has more experience with F@H can help me set it up to run along side. I'm sure it's just some setting or tweak I didn't do but I remember it took nearly an entire CPU core. Ideally I would like it to be 5% like when BOINC uses GPU, but I'll still run it if I can get it below 20%
