Less Interactivity than before?

[Googolplex]

But you could make an option "Enable interactive objects" for high end computers which are powerful enough to handle an acceptable frame rate.
The game already used 4-core CPUs compared to TDD. There could be one thread just for interactive objects. This option should be disabled by default and only active for users with high end hardware.

But you are right that the blue light looks ugly for interactive objects. I always hate it in games, because that destroys a realistic feeling. Even TDD shouldn't have it.
