       | It seems to be typical - some calculations break while switching
       | from x87 to SSE. The same happened with TF2 too - it's ammo
       | calculation code worked slightly differently on GNU/Linux build
       | of the game, because it was built with SSE instructions (Windows
       | version still used x87).

       | Wait, so is that "beta" of Half Life 2 VR a thing I can play? If
       | it is, how did I not know about this, and if not... why not?
       | 
       | I'd also love to play Portal, actually. They say it makes you
       | sick, but to my knowledge I'm immune from VR motion sickness, so
       | worth a try...

         | I don't know about the beta, but there's an excellent HL2 VR

         | me to play HL2 again after all these years.

         | through. Surprisingly comfortable to play too.

       | well if games break even after switching from x87 registers to
       | SSE preserving all the logic otherwise...
