FrameView

A proprietary utility from NVIDIA that allows you to display additional information about the operation of the video card in the overlay and evaluate the performance and power consumption of the video card. The output is carried out in one of the quarters of the screen.

The program offers several monitoring and statistics tools, and is mostly intended for enthusiasts and streamers. The main functionality allows you to:

• determining the frame rate during rendering, i.e. at the beginning of graphics processing, and the frequency of displayed frames, i.e. at the end of the processing process;
• Frame rate scores at the 90th, 95th, and 99th percentiles. Reviewers typically use the 99th percentile. If it is close to the average value, then we can say that the game is displayed smoothly and without jerks;
• launching benchmark mode. In this mode, pressing a hotkey begins capturing statistical data for a previously preset period of time. To maximize performance, the overlay is disabled for the duration of the benchmark.

To estimate energy consumption in games, the utility allows you to display the consumption of the GPU. This value is coded in the overlay as "CHP". It is also possible to determine the power consumption of the entire video card. This parameter is called “TGP” and it does not take into account the power consumption of devices connected to the USB-C output of GeForce RTX video cards.

In addition, there is a definition of specific energy consumption, “PPW”. This value represents the performance per watt over the last few seconds, and is calculated using the formula: F/J = (F/S) / (J/S)

Open Graphics Library or OpenGL is a development of Cilicon Graphics. It is used when writing games with 3D graphics. A common error associated with this library package is “the file opengl32.dll is missing.” Its reason is that the requested library was deleted by a third-party program or user. This often happens when installing hacked games. Applications from torrents do not always come complete with all the necessary components, unlike licensed versions. The repack can remove or damage opengl32.dll during installation, and it can also replace the original dll with its own version. This causes all applications using OpenGL to start throwing an error.

Another common cause of failure is the antivirus program. When installing a dubious game, the antivirus may consider its libraries dangerous and isolate them. If this happens, then simply return opengl32.dll from quarantine and add it to the exclusion list. If the file is damaged or deleted, then fixing the error will be a little more difficult.

The algorithm of actions is as follows:

• Reinstall the game
• Download opengl32.dll
• Install the entire OpenGL package

As soon as you understand what kind of error has visited you, try reinstalling the problematic program. This will certainly help if you are using a licensed game. It will replace all suspicious libraries with original versions, after which everything will work. If the game was downloaded from a torrent, reinstalling it will hardly help. It would be better to look for another build of this game and try it. Didn't help? Then download opengl32.dll from the network and put it in the system folder. You can download the current dll for Windows 7 or higher on our portal. If you have an x86 system, then put opengl32.dll in C:\Windows\System32. Windows x64 users will need the C:\Windows\SysWOW64 folder. Once the library is in place, register it and launch the game. Now you know what to do if you have an opengl32.dll error.

In 2015, the open consortium Khronos Group, which includes software and hardware developers, released the OpenGL ES 3.2 specification. It covers almost all smartphones and mobile devices using the Android OS. Plus, the OpenGL 2015 ARB extension was introduced, intended for desktop computers. In connection with these events, NVIDIA has released a new version of OpenGL Driver for its video cards. This set of drivers allows you to use the new features of OpenGL ES 3.2 or OpenGL ARB for all GPUs built on the Maxwell, Kepler or Fermi architecture.

OpenGL is a special technology and application of the same name that allows you to work with two-dimensional and three-dimensional graphics. The application not only provides high computer graphics performance, but also provides the user with detailed information about the computer's graphics system.

Specification

OpenGL appeared in the early 90s for 32 bit systems. The goal of the developers was to create a software product that could run on completely different video cards. For example, a game developed using OpenGL could now run on any video card that supports this specification.

This was ensured by the software implementation of capabilities that were not supported by the device, allowing the development of software for low-power computers. Since then, the technology has continued to develop, and is now available for all devices with the Windows xp/ 7/ 8/ 10 operating system.

In particular, the following video cards are supported:

1. nVidia.
2. Intel HD Graphics.

In a normal situation, the computer does not require this technology. However, when trying to launch a modern game (for example, Minecraft), the error “Error support. Openal.dll not found" warning that you need to install OpenGL for it to work correctly. To solve the problem you need to install the OpenGL library. On this site you can download the latest version of OpenGL.

After installing the driver, not only does the error disappear, but system performance also improves and additional features appear. After installation, you can find out information about your graphics system. In versions for most video cards, the program icon appears in the system tray. If you click on it, you can view this information.

This software also provides the following features:

1. Checking video card performance using built-in or third-party tools.
2. Testing the 3D capabilities of the system.
3. Displays a list of image output technologies supported by the installed driver.
4. More subtle graphics card settings that can improve performance.

OpenGL technology cannot harm your computer in any way. Installation takes place in a couple of mouse clicks and the program itself does not load the system in any way. If the installation is unsuccessful, this can be cured by simply reinstalling or removing the driver.

For everything to install successfully, you need to download the appropriate version for your system. For a 64-bit system you will need OpenGL x64 bit, for a 32-bit system - x32, respectively. You can find out the bit depth of your OS Windows by simultaneously pressing the key combination “Win+Pause/Break”.

OpenGL's main competitor is DirectX technology. Compared to it, OpenGL has the following advantages:

1. Better 3D graphics performance.
2. Multiplatform. DirectX was tailored for Windows OS, while OpenGL can run on various systems, be it smartphones or game consoles.
3. Support for a large number of video adapters, each of which has its own version of the program.
4. Backward compatibility. All applications written using older versions of the standard will work in the new ones.

Download

For the average user, this technology has no disadvantages. It improves PC performance without overloading the system. The only controversial drawback can only be felt by programmers - OpenGL uses a low-level API, which makes it more difficult to work with than DirectX. However, it is low-level development that provides high performance and stability.

In most cases, a package of files called OpenGL is required by users to correctly run certain games on a computer running the Windows 7 operating system. If this driver is missing or its version is outdated, the programs simply will not turn on, and a corresponding notification will be displayed on the screen asking for installation or update BY. In this article we will talk in as much detail as possible about loading new OpenGL libraries.

First of all, it’s worth understanding how the component in question is installed on a PC. All necessary files are installed along with the graphics adapter drivers. Therefore, you should first update the software of this component, and then move on to analyzing the alternative method.

When you have the latest driver installed on your video card and there are no more updates, but a notification about the need to update OpenGL still appears, immediately proceed to the third method. If this option does not bring any results, it means that your equipment does not support the latest libraries. We recommend that you think about choosing a new video card.

Method 1: Update video card drivers in Windows 7

As mentioned above, OpenGL components are installed along with the graphics adapter files. Windows 7 has several methods for updating them. Each of them is suitable in different situations and requires the user to perform certain actions. Go to the article at the link below to get acquainted with all the methods in detail. Choose the one that suits you and follow the instructions provided. Once the process is complete, just restart your computer and check the functionality of games or other programs that required a new version of the library.

Method 2: Updating components in the video card proprietary utility

Currently, the main manufacturers of graphics adapters are AMD and NVIDIA. Each has its own software that ensures correct operation of the operating system and allows you to update the software. Owners of NVIDIA video cards are advised to refer to the material at the following link to understand how to install the new version of the OpenGL driver in GeForce Experience.

Owners of AMD cards need to read other articles, since in this case all actions are performed in the Catalyst Control Center or in Radeon Software Adrenalin Edition, depending on the type of software installed.

Method 3: DirectX Update

Not the most effective, but sometimes working method is to install new DirectX library components. Sometimes it contains suitable files that allow the necessary games or programs to function normally. First you need to find out which DirectX is already installed on your computer. To do this, read the instructions in the article below.

At the moment, the latest version for Windows 7 OS is DirectX 11. If you have an earlier library installed, we recommend updating it and checking the functionality of the software. Read more about this topic in another article.

As you can see, there is nothing complicated about updating OpenGL; the main issue is only support for the latest files of this component by your video card. We recommend testing all methods, since the effectiveness of each depends on different circumstances. Read the instructions and follow them, then you will definitely succeed.
