Hi all. I'm a bit at loss here. Even when I try to push FSX to the max, it seams the machine is not giving its 110% ;-)Take a look at image of the task manager below. It pretty well represents the cpu usage through monitoring a flight session. The max it will reach is about 62-63% throughout the run. Most often it hovers around 50-54% has can be seen in the 2 rectangularwindows. A friend tells me that its CPU Usage alway shows 100% during a similar run11 I think he has a P4, 3.4 or 3.7 MHz and he's got 1 GB of ram memory as I have.The device manager reports the computor as a multiprocessor type!!?? Yet it's a single one, P4, 3.0 MHz with hyperthreading capacity (it is set for in the bios). It's a socket 478 type, if one needs to know.In the second image, you can see the SiSoftware Sandra lite Computor Overview and Processors reports. Le latter only showsthe Core 0, Thread 0. There is a similar one for Thread 1 that shows the same.I realy wonder if something is wrong at the bios setup, hence limiting the processor to deliver everything it has in the guts.System: Asus-P4P800SE, P4 3.01G (socket 478), 1GB PC3200 (400MHZ), XP Pro 32.I'm not an hardware geek but any (all ;-)) comment and suggestion would be appreciated.Thanks,Hugo

Bump!Noone has the slightest idea?Hugo
