# For a 64bit + 32bit system the LD_LIBRARY_PATH must contain both the 32bit and 64bit primus

# libraries. Providing a different primusrun for each architecture will not work as expected. EG:
|

|
|
# Using steam under wine can involve both 32bit and 64bit process. All of which inherit the
|

|
|
# same LD_LIBRARY_PATH.
|

|
|
# Other distributions do the same.
