--- Comment #37 from Sebastian Lackner <sebastian at fds-team.de> ---
I wanted to reproduce this issue, and decided to install the Demo of "Lara
Croft: Guardian of Light".
A check using the ProtectionId tool looks like it indeed uses CEG:

But... I cannot reproduce the issues with file validation (succeeds without
downloading new files, no message on terminal), and the game also seems to work
properly (besides some wined3d rendering issues... most likely needs CSMT or
strict draw ordering). Testing with wine-1.7.24-14-gd1749b5, without any
additional patches.

The title of this bug report is probably a bit misleading, as it doesn't seem
to affect all CEG protected games.
I will test with the demo linked in the description
(http://store.steampowered.com/app/55150/) as a next step.

Regards,
Sebastian
