Comment (by mtojek):

 I wanted to refresh this issue. I've tested Syberia 1 on mid-end handheld
 (trimui smart pro, OpenGLES3.2 via libretro) and unfortunately I don't any
 huge performance difference between SW and HW rendering. I agree that the
 main menu is lagging so hard that it takes a minute to move mouse pointer
 to "new game".

 There are not many 3d obj changes in the scene, so why does Syberia lag so
 much?
