Download nvidia software. NVIDIA PhysX. What is it and why is it needed

Description: NVIDIA PhysX - A powerful physics engine that provides realistic real-time physics in modern games for computers and consoles. More than 150 games are powered by PhysX software, more than 10,000 developers use PhysX in a variety of fields, and the software itself is supported by Sony Playstation 3, Microsoft Xbox 360, Nintendo Wii and PC. It should be noted that PhysX technology is designed specifically for hardware acceleration using powerful processors with hundreds of cores.

Additional Information:
Implementing physics in games is not such an easy task. This area is extremely computationally intensive and is based on a unique set of physical algorithms that require an incredible number of simultaneous mathematical and logical calculations to implement. This is where NVIDIA® PhysX™ technology and GeForce® processors come in handy. In addition, PhysX technology is designed specifically for hardware acceleration using powerful processors with hundreds of cores. Combined with the GPU's incredible parallel computing capability, PhysX will provide an exponential boost in physics processing power and elevate gaming experience to the next level, delivering rich, immersive game environments with features such as explosions that raise dust clouds and turn everything into ruins, characters with complex geometry brimming with connectors for more realistic movement and interaction, new weapons with incredible effects that make a lasting impression, fabrics that tear and wrinkle realistically, thick smoke and fog rising around moving objects. There is the only way To get real physics with scale, sophistication and precision that will drastically change your entire gaming experience, is to use one of the millions of NVIDIA PhysX-ready GeForce processors.

If you like to play modern games, then surely high quality graphics is crucial for you. Drawing three-dimensional objects, a large number of polygons and shaders, an excellent level of simulation of physical objects - all these are important points that you probably pay attention to when playing.

One proprietary engine for simulating the physics of 3D objects is NVidia's PhysX. Unlike most modern engines that are included with the game distribution, PhysX needs to be installed separately. Installs PhysX as a discrete driver. Also, a special board installed separately can be used to process graphics. In this case, the engine driver will use its resources during operation. In the absence of such a hardware component, all the tasks associated with calculations will be assigned to the "shoulders" of the central processor.

The Physics engine itself includes three main components that process physics:

• liquid handling;
• tissue processing;
• processing of solids.

If you install the PhysX SDK library, you can personally observe the work of these three components of the engine in relation to the processing of polygonal objects.

PhysX is used exclusively on NVidia video cards starting with the GeForce 8 series and later with a minimum of 256 MB of video memory and 32 cores. If you want to use the NVidia graphics adapter for graphics processing with PhysX, other graphics cards in the system must also be equipped with an NVidia GPU.

Possible problems and solutions

Quite often, during the installation of the PhysX driver, errors with serial numbers 1316 or 1714 appear. This problem is associated with incorrect removal of old drivers when they are reinstalled on an NVidia video card. This problem is observed in Win 7 and above. At the same time, PhysX is not installed at all. It is worth noting that when using special software systems and utilities for cleaning the system (Reg Organizer, Driwer Cleaner, Drive Sweeper), the problem cannot be solved. Most likely, you will have to remove the old NVidia libraries from the entire PC memory.

The author of this article had such a problem with PhysX when it was decided to replace the GeForce GTX 560 video card with a GTX 670. Of course, the old driver simply won’t work for the new video card, and the operating system will start throwing various errors. Here are instructions on how to deal with this.

It doesn't matter if you uninstalled the old version of PhysX or not, be that as it may, we launch the Driver Cleaner or Driver Sweeper application, with the latest version.

In the list of drivers, check the box next to the option NVIDIA-PhysX and click on the "Analyze" button.

Manually select all those items that were found by the application, clean up and proceed to the next operation. If the program could not find anything, we also proceed to the next step.

We check the folder C:\Progam Filess (x86) for a 64-bit system or Progam Filess for a 32-bit OS, respectively, and find the NVidia Corporation directory there. If it has a PhysX folder, delete it.

It is not yet possible to correctly install PhysX on Windows 7, you still need to clean up the registry. Let's use the keyboard shortcut Win+R and run the command regedit. This will open the Registry Editor. It is important to understand that in case of incorrect deletion of keys in the registry, you can lose the reliable performance of the system, or the operating system will stop starting altogether. Therefore, before proceeding with manual cleaning, do it using the same utilities for working with registry keys that were discussed earlier.

After the drivers were removed from the system, and the registry was cleaned with a special software package, the author of this article managed to find a dozen more remaining keys in the registry, so we only clean everything with pens.

Click Edit -> Find. Set the search field to "physx" and click "Find Next"

If all the fields in the open branch have something to do with PhysX, delete the entire folder. If you see that the branch contains keys related to other software products or technologies, delete only those keys in the name or meaning of which the search word occurs. All other keys are found using the Find Next command.

The entire manual cleaning process will take you about an hour, so please be patient. Agree, it is much easier to carefully clean manually than entirely. And it will take much more time to set up additional software (archivers, file managers, drivers for components), so the game is worth the candle.

When the registry is cleared, restart your computer and you can proceed with the installation new version PhysX from the NVidia website, available for download. Now you know how to competently and absolutely correctly reinstall PhysX on the Windows OS line. After that, the problem with errors should disappear, and everything else will go "like clockwork".

Most gamers who have an NVIDIA graphics card installed in the system unit, or just in the game settings or somewhere else, have seen such technology as NVIDIA PhysX. Many people know what it is and why it is needed, but many probably do not. I will try to tell in more detail about NVIDIA PhysX what it is and what it is for.

general information

Initially, PhysX was developed not by NVIDIA, but by the American company Ageia Technologies. In February 2008, this company was acquired by NVIDIA Corporation and completely became part of it. Naturally, all developments of Ageia Technologies have also completely become the property of NVIDIA. After that, PhysX was renamed to NVIDIA PhysX and all active development was focused on it. The engine has been optimized for accelerated physics calculations on graphics chips that also have NVIDIA's CUDA architecture.

But what exactly is NVIDIA PhysX and why has it gained such popularity? NVIDIA PhysX technology offers better game process and a richer gaming experience, delivering more realistic environment and character interactions than ever before. Thanks to more realistic behavior, graphics look and feel much better.

PhysX is a cross-platform physics engine that eliminates game developers from the need for a long, expensive independent development of their own software, which is responsible for the physical interaction of various objects.

PhysX technology is designed specifically for hardware acceleration through powerful processors with hundreds of cores. As a result, NVIDIA GeForce delivers a significant performance boost in physics processing and elevates gaming to a whole new level, delivering rich, immersive gaming environments with features such as:

• dense smoke and fog that swirl around the object while moving;
• fabrics that naturally flutter and tear;
• characters that are made up of complex geometry for more realistic interactions;
• weapons with incredible effects;
• and many other items.

The engine itself consists of 3 parts:

• solid body processing rigid body);
• textile processing cloth);
• liquid handling fluid);

Currently, PhysX technology is used in more than 150 games. NVIDIA PhysX is the most widely used physics engine in the world!
