I have installed a new version of Process Explorer v15.3 and it has a new tab GPU.It is very useful, but I cant't understand what means feature called Engines. On my Radeon Mobility HD 5470 1 Gb it shows 6 engines. When I run some heavy 3d game I see only one engine active (0).Now when I have Chrome browser opened it shows small activity of 5 Engine. So does anybody know what hardware graphic card elements do this engines show and corresponds? Is there some detail information about their realisation?Thanks in advance.
