The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
-Installation from Steam
-Full game played from start to finish
-Maximum graphical settings (every parameters at the highest level, 1600x900 resolution, 8x
anti-aliasing, 8x anisotropic filter) at performance indiscernible to that of the game played a Windows system. Really.
-Played using an Optimus laptop , with Optimus technology (incompatible with GNU/Linux systems) being replaced by Bumblebee ("optirun" command). Not a single problem.
-Saves save and load very well. Screenshots work fine too.
What does not
Candles create a mild visual artifact, but it's neither game breaking, nor completely disruptive to the experience, as the previous tester mentioned.
