Whether you use the 2nd graphics card under PhysX calculations? (Assassin's Creed: Odyssey)

This topic is old. It was important for the old vidyuhi type 8800,280 old and weak percent. And the modern percents and good vidyuhi not need the second, under PhysX.
And so put and set up the card under PhysX is for Nvidia+nvidia. But NVidia+AMD, one person writes:
Spoilerroom FluidMark which is part of the PhysX SDK. Feature of the new version of the PhysX SDK is no need to install NVIDIA PhysX System Software.

Hybrid PhysX ATI Radeon PhysX mod Owners of ATI Radeon support Hybrid PhysX ATI Radeon. The Radeon hd plus GeForce 8 and higher still – favorite games support physx. Nvidia physics games.

What is PhysX – physics? NVIDIA PhysX – physics engine to provide the user with realistic physics (a picture) in leading computer games (about 150 games) in real-time. The GeForce greatly enhance the performance and image quality when processing physics, raising the quality of the game to support PhysX to a new level. So. Since Nvidia bought Ageia and monopolized the PhysX acceleration of physical effects, the progress in this area, the ardor and aspirations of game developers a few pougasla. The cause is trivial, the restriction to use only GeForce video cards and accelerators Ageia. On the cards of competitors ATI PhysX does not work...

In addition, upon detection of an ATI Radeon "outsider" support PhysX driver is blocked. Of course, such "miracles" do not give popularity and has a negative impact on the number of games and fans. But fortunately, there is a silver lining, and that seems to be looming light at the end of the tunnel – Hybrid PhysX, hybrid allowing the use of an ATI Radeon in conjunction with the Nvidia GeForce. If you are the owner of Radeon HD, and you are interested in the game strongly recommends the use of PhysX System Software, do not worry, there is a solution – you need PhysX for ATI.

There's also Havok after all.
