I am setting a ridiculously demanding scene up in iC5 as it has wire frame, unshaded, quick shaded modes for the whole scene unlike iC6 but made the mistake of clicking pixel shader sending my RAM to 100%, my 980ti was already over 6 GB so kinda knew I was asking for trouble.
My only recourse will be to try to bring up task manager and kill iClone but that may not even be possible, may need to cut power.
If I could bring up wireframe could save and exit, it will load in iC6 have done so with more figures just hard to work with making them individually wireframe.
Control Z only undid my last actions not switch back to quick shader where I was before I stuffed up.
If I knew a keyboard shortcut to switch modes it would stop me doing it again because cannot move mouse to tab to click pixel shader to wireframe if this happens, it is all just frozen, I know the issue, texture maps too big and one in wireframe can set size smaller.
I accepted will lose this scene, I would like to know if there is a shortcut if I do it again.

Dam Windows right arrow enter will not even shut the bugger down, do not want to but may need to kill my power

Thanks all but sadly I had to switch of the power as nothing would unfreezeit, I did try ctrl alt del first, even the on button would not bring up shutdown, win key right arrow enter usually will do it but was beyond help, reducing the textures made the scene useable btw as I suspected.
