PS3Grid Clients etc...

Windows
They are almost there with the Windows client. Using my Quad example from above, Windows will crunch 4+1 with no special input from the user (if crunching a GPU wu). But the GPU will be using ~15-17% of the cycles from 1 CPU (and it will not be running at top speed). Users can continue to operate their client at 4+1, and GPU wu's will run at reduced efficency for now. But, to get maximum GPU crunching speed using the Windows client, Users have to dedicate 1 CPU to the GPU. Right now, under Windows the GPU requires ~20-35% CPU cycles to crunch at top speed. So for best GPU results (shorter run times), some users are running 3+1 only .

On Doomeva's Intel Wolfdale E8400 45nm core 2 duo running at 4GHz under Windows XP Pro 32bit one core is on 3x+1 and utilising 50% the other core is on GPUGrid and it hovers between 41-43% CPU usage, so 7-9% of cycles are "wasted". Its using BOINC v6.3.21. The motherboard is an ASUS P5E-VM HDMI.
