ok, thank s a lot

i didnt find on ressource monitor of w7 task manager but i havent the wow pc with me for few weeks, i ll search when i ll come back home.
i read my old screen and i see something strange in the reading disk.




first wow is main 1900X1200, other are 4 clones 1024X768 and all same around 525 Mo ram
C is velociraptor, D is old data samsung and F raid ssd ... in full work
You can see, except the main with reading 59 MB/min, each clone is half of half reading. 3.4 MB/min 2.5 MB/min 1 etc ...
it s look like the system remember a little the graphics data for the GPU

Edit : thank s for the mistake in GB MB
