Final Thoughts and Conclusions:
With the game coming out roughly three months from now it’s too early to make any calls on the performance front, but for now the NVIDIA graphics cards do much better handling the benchmark in the techdemo. Offloading the physics calculations to the dedicated PhysX card worked great at lower resolutions where the system wasn’t bound by the CPU and GPU as much. By doing this offloading it let the NVIDIA GPU perform more essential calculations and the average frame rate improved, which is the desired result. Forcing the GPU to do more work (i.e. PhysX) will just slow things down, and the proof is in the performance numbers.
One important thing to take away from this is the huge step forward in environment quality that physics will enable. Rather than having static water textures and terrible hair and cloth simulations, we will now be able to create even more realistic environments and bring gaming one step closer to reality. We aren’t going to outright endorse Nvidia’s PhysX engine as the route forward but we must give credit where credit is due for advancing GPGPU adoption. Hopefully, we’ll get to the point where any physics engine will run on any GPU, but for right now, it’s such a new technology that it makes sense for Nvidia to hold onto this piece of technology for as long as possible.
Legit Bottom Line: The Physics in Cryostasis are amazing and you should download the demo and see them for yourself!
