Does Raycasting require a PhysX enabled video card?
After having some problems implementing raycasting into my project, I decided to try running my project on another machine.
To my surprise, while raycasting would never produce a hit on a collider on machine #1, machine #2 would behave as expected.
I've confirmed that both have:
The same version of Unity
An exact copy of the project files
The same version of Windows
The only difference I've been able to find is that machine #1 does not have onboard PhysX and #2 does.
Does Unity require your video adapter to have on-board physics acceleration to use raycasting?
No other physics features seem to be affected, and I would have assumed that Unity had a non-hardware fallback if it did use accelerated raycasting.
The answer to my original question is no.
Apparently, I had accidentally clicked the button to filter out all logging statements in the console, which was stopping me from seeing the debug statement that confirmed the raycaster was working.
For sake of completeness these are the system Requirements:
