I'd love to try a few different concepts:
Text based, FF or Fictional Force based on some of the inspirational examples
Picture/logo/brand based: a simple clean image that represents the vision of the company.
one thing to think about is that we are bring simulator motion to VR.
I'm don't want to specifically design for VR in the logo, but taking real world motion and simulating that is a theme to think about.
Another thing to think about is the idea of digitizing motion. The idea of representing motion with vectors (arrows) is an interesting design idea, but I'm open to other interpretations of motion.
One idea that comes to mind, since we're taking one force (real world) and translating it into a synthetic/simulated one, could be an interesting play to have one F feed into the second. Like its transferring energy from one to the other.
Don't feel obligated to incorporate the f's in the logo. If you can come up with a cool idea that has the idea of force and virtual reality or fictional forces or digitizing motion.
it might be worth looking at what force vectors look like in physics and mechanics. There might be some inspiration there:
Vectors, arrows, blur, forces, motion, gravity, virtual reality, physics, velocity, dynamic, agitate, move, movement, thrust, push, apple, Newton, acceleration, energy, momentum, inertia, dynamic,kinetic
