If this technology is widely used in the game, it will make the scene in the game more realistic. For example, if you shoot at a wall in the game, ordinary games just leave a few bullet holes in the wall or drop a few cement blocks, but if you have the PhysX function, the cement blocks on the wall will keep falling until more than half of the wall collapses, revealing the steel bars inside, which is similar to the real world. If the characters in the game wear windbreakers, the windbreaker will swing randomly when running, unlike other games, which only swings from side to side, which is very unreal.
If you want to have PhysX function, you must meet three requirements:
First, the graphics card must have PhysX technology (this is not difficult, because the graphics cards produced by NVIDIA since 2008 have PhysX technology regardless of performance). And AMD's graphics card is a tragedy. Because PhysX is a patented technology of NVIDIA, AMD can't get the authorization of NVIDIA (who makes AMD and NVIDIA competitors), so all types of graphics cards of AMD don't have PhysX technology. If you want to experience PhysX, you can only use NVIDIA's graphics card.
The second is to install the PhysX software package in the operating system, which is what you think of as the PhysX system software (this is also very easy, because NVIDIA's graphics card driver comes with the PhysX software package, and after installing the graphics card driver, the PhysX software package is automatically installed).
Third, the game must also support PhysX technology, which is the most difficult.
