Debian Multimedia :: Jessie 64-bit Steam Crashing With AMD Fglrx Drivers

I recently switched over to Debian 8 "Jessie" (64-bit Cinnamon flavor) on my Desktop.

250GB SSD
16 GB DDR3 RAM
i7 4790 Processor
AMD Radeon R9 280X

I have been able to play multiple games on Steam without any issues, however I have downloaded Ark: Survival Evolved and am unable to actually play that game in particular. I can log in and get to a point of choosing a server, but after it actually loads to the game(where it starts rendering graphics), the game crashes to the desktop. Below is the readout of the crash from when I loaded Steam via Terminal.

Code: Select all   
    Signal 11 caught.
    ERROR: ld.so: object '/home/lukasz/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
    ERROR: ld.so: object '/home/lukasz/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
     
[Code] ....

I have noticed that the above (zenity:13343): Gtk-WARNING line in terminal is the point at which the game crashes. It would appear that the steam gameoverlayrenderer.so is a separate issue and may be a common occurence in the background that you just don't see.(?)

Things that I have done thus far:

-Verified that the video card is good
-Tried Open-source graphics drivers
-Currently using the AMD 15.9 Proprietary Drivers directly from AMD with Catalyst Control Center.
-Reinstalled "zenity" to ensure that it was not corrupted.
-Verified which Gtk+ versions that I have installed(see below)

Code: Select all   
    lukasz@Lukasz-Desktop:~$ pkg-config --modversion gtk+-2.0 gtk+-3.0
    2.24.25
    3.14.5

Is there a "default" gtk+ version that I have to alter for it to recognize that I have Gtk+ 3.0 installed, or did I miss something somewhere?

My hypothesis:

-It has something to do with 32-bit/64-bit conflictions(Maybe the game? My steam is 64-bit)
-My graphics card may not be supported by Ark: Survival Evolved yet.
-I am missing some libraries each time I have attempted different video drivers.
-Something with steam did not get installed correctly(I have not attempted to uninstall and reinstall it, however other games function correctly)
