Running this game without having made any modifications leads to flickering textures and major physics problems. Steam does state that it requires Windows XP but I encourage players to ask for a proper fix from Steam/Gearbox. I recommend some .ini settings as well that improves mouse movement and enables EAX.

1. Create a shortcut from the game executable in the game "System" directory (eib.exe).

2. Use shortcut to set compatability mode to Windows XP Pack 3.

3. Set run as administrator (not sure if this step is absolutely necessary).

4. Use the Task Manager or better something like Process Lasso to set game executable (eib.exe) CPU affinity to a single core, preferably not the first core (core 0) as the windows system uses that.

5. Edit User.ini file C:\Users\tempo\AppData\Roaming\Gearbox Software\Earned In Blood\JoeHartsock\

6. Set MouseSmoothingMode to 0.

7. Set bEnableEAX to true.

8. Edit eib.ini in same folder.

9. Set DesiredRefreshRate to the refresh rate of your monitor.

10. Set UseDefaultDriver to false (Star Wars Republic Commando - same engine - "This tells the Unreal Audio Engine to load OpenAL32.dll from the \windows\system32 folder which will result in a native OpenAL being used." - http://web.archive.org/web/20130702030043/http://connect.creativelabs.com/alchemy/Lists/Games/AllItems.aspx

I think that's everything. Enjoy the glory that is BiA !
