#14452: TETRAEDGE: Syberia 1/2 rendering issues on big-endian
----------------------+-------------------------------
Reporter:  dwatteau   |      Owner:  (none)
    Type:  defect     |     Status:  new
Priority:  normal     |  Component:  Engine: Tetraedge
 Version:             |   Keywords:  big endian
    Game:  Syberia 1  |
----------------------+-------------------------------
 I have a late PowerBook G4 running OSX Leopard, Debian and OpenBSD. I'm
 testing the Syberia 1 & 2 Macintosh games from GOG with a recent build
 from the master branch.

 The games do start, but there are various rendering issues (see the
 attached screenshots) and moreover everything is extremely slow (whether
 in OpenGL or TinyGL mode), to the point that even moving the cursor to the
 small hitbox of the "New game" or "OK" buttons takes ages.

 For some reason, Syberia 2 has a more tolerable framerate than Syberia 1.
 Maybe it's related to the bigger video in the menu for Syberia 1? For
 reference, Grim Fandango, Escape from Monkey Island and The Longest
 Journey run pretty well on the same machine.

 I'm attaching some logs for reference. Some come from the Instruments and
 OpenGL Profiler OSX apps. Looking at `top`, it looks like the game is
 being quite CPU-bound.
