I've noticed that PCSX2.exe doesn't use 100% CPU on my core i7-930 (checked the usage via TaskManager). The highest I got was 75-80%.
I'm using GSDX SSE4 in DX11-Software mode, SW thread count is set to 4. I have Hyperthreading turned off in BIOS since I don't really need 8 virtual cores for anything. When I change the PCSX2.exe CPU affinity to 3/4 I get a significant slowdown, which I guess means that it's really using all four cores, but obviously not to the full extent. All emulator settings are at default.
I tried both the latest public beta and compiled latest SVN source (Release config, VS2010), but other than significant speedup in the SVN version CPU usage is the same in both cases. I even tried null-ing pad and spu plugins to see if they are the culprit but no joy.
Any ideas?
