Hi, I have PVsyst v5 installed on one computer with a Q6600 processor and PVsyst v5 only uses 25% of processor (one core). There is a new version that uses full capacity of Core 2 Duo/Quadcore processors? Note1: If I use with a QuadCore (Four cores), PVsyst v5 uses 25% of processor capacity. Note2: If I use with a Core 2 Duo (Two core), PVsyst v5 uses 50% of processor capacity. Note3: If I use with a Pentium 4 with only one core, PVsyst v5 uses 100% of processor capacity.
