Your VRAM might be leaking confidential data

[Trik'Stari]

How is this possible? vRAM and RAM are both volatile memory and are supposed to be zeroed out upon power down.....

 

Enhance! ENHANCE!

That's one of my favorite moments in that movie...

 

Better run boku no pico a few times before turning off PC, then.

Exactly my thoughts. Vram is supposed to be volatile. What is the fuss about?

It's volatile, yes, but because laptops have internal batteries, during a single reboot cycle, sufficient power might still be trickling to the GPU VRAM, thus preserving at least part of the frame buffer.

 

I imagine that a full power off - power on cycle, rather than a reboot cycle, would be sufficient to erase the frame buffer.

Some power supplies continue to trickling power for about 10-15 seconds after shutdown, if you manage to start the computer back up within that time frame, you're in, also some laptops still have a bit of power trickling when they're off.
