Nvidia Physx Function
Ive read that it can be handled by either the cpu or the gpu with an old cpu and a new gpu is it preferred to let the gpu handle it.
Nvidia physx function. Physx is an open source realtime physics engine middleware sdk developed by nvidia as a part of nvidia gameworks software suite. The timestep can vary each frame or it can be a fixed step. Initially video games supporting physx were meant to be accelerated by physx ppu expansion cards designed by ageia however after ageia s acquisition by nvidia dedicated physx cards have been discontinued in favor of the api being run on cuda enabled geforce gpus. Experience gpu physx acceleration in many games and demos some of which are highlighted in powerpack downloads here.
Physx is optimized for hardware acceleration by massively parallel processors. This is beneficial because a gpu has. Runtime upgrade only for ageia physx processors. Nvidia physx is a powerful physics engine enabling real time physics in leading edge pc games.
Physics calculations can be very complex and therefore as a system requirement a gpu must feature 256mb of dedicated local video memory support nvidia s cuda technology and also have 32 cores or higher. Why use a boutique graphics card instead of a beefy cpu. Physx is an nvidia based api designed to provide a standard gpu accelerated way of modelling realistic object dynamics in 3d environments. Typically game developers call physx with a timestep in the range 1 60 seconds to 1 30 seconds.
Physx has a function pxscene simulate which takes the timestep as a function argument. Wondering a bit about physx and lets say if i dont select to install it at all with nvidia drivers what will this affect and are todays games using it at all. In physx any physics object you want to make you need to fill a relevant descriptor and then pass that descriptor to the sdk function through the physx sdk pointer responsible for creating the object for you. Nvidia physx api uses the gpu graphics processing unit to process the physics environment calculations in games and applications which support nvidia s physx.
Physx is simulation technology that can be integrated into real time graphics engines aka games and allows physics calculations that would usually be performed on the cpu to be calculated on the gpu instead. Physx software is widely adopted by over 150 games and is used by more than 10 000 developers.
