As the beta continues we are working out the kinks prior to launch.
v1.0.3 contains the following fixes:
-Corrected issue with some dog skins not rendering correctly
-Corrected issue with graphic settings not being applied correctly on some systems
-Graphics settings not saving or loading
-Corrected issue with reward levels not being applied correctly
We are aware of a few other performance related issues and those will be fixed within the next few days and prior to the game release.
