OK so I'm not sure if this is specific to my Windows setup, or if I'm doing something wrong. I have two machines with VO installed. Both run Windows 7 x64, the main machine has a Radeon HD7770 2GB onboard (BitLocker full drive encryption), the notebook has a GeForce GT820M on it (no BitLocker).

I press F12 at some point and I can see the game doing something, then telling me "screenshot saved" etc.

It's dumped into the installation folder. But when I open it, the file is only 3K in size and is just black.

Any hints or ideas how to rectify the situation?

Is it happening on both of your machines or only one? We've seen that on Radeon-based systems but have not figured out why it happens.

This is happening on both machines, on both the drivers are the current version.
