How to run Fallout 3 on MacBook Intel graphics chipsets
Raw
fallout-3-macbook-intel-graphics-fix.md

I had trouble getting Steam's version of Fallout 3 to work on my MacBook Pro in Windows. The main menu would start, but the game would crash after I clicked "play", just before the intro movie.

Turns out the issue was related to my MacBook's Intel graphics chipset, an Intel Iris Graphics 5100. To get FO3 to work, I was able to use the Intel HD Graphics Bypass package to trick FO3 into thinking it's running on an Nvidia chipset.

If you're running an Intel graphics chipset, and can't get FO3 to run, this fix may work for you too:

  1. Manually download and extract the Intel HD Graphics Bypass Package
  2. Copy d3d9x.dll --> C:\Program Files (x86)\Steam\steamapps\common\Fallout 3\
  3. (Optional) Create a backup copy of C:\users\$USERNAME\Documents\my games\Fallout3\FALLOUT.ini
  4. Copy FALLOUT.INI --> C:\users\$USERNAME\Documents\my games\Fallout3\
  5. Make sure the FO3 options window reports your "Graphics Adapter" as "NVIDIA GeForce 7900 GS", otherwise double-check step 2.

Based on step 7 of the ULTIMATE Fallout 3 Setup Guide. (If you have other issues running FO3, this is a great place to start.)
