Why FPS sags in games: reasons for lags and ways to optimize a computer

Why does the FPS sag in games? A similar question was asked at least once by any gamer. And although there are a lot of ways to optimize a computer, the reasons for lags almost always lie in the insufficient consumption of RAM. But what leads to such a "symptom" and how to raise FPS in modern video games without resorting to the help of a specialist?

Perform system diagnostics

Have you thought about why the FPS is sinking in KS: GO or DotA? Then you must first and foremost conduct a general diagnosis of the system, because quite often the reason for the lags lies in the presence of a malicious program or process that consumes computer resources. To do this, open the task manager (Ctrl + Alt + Del), and then go to the "Processes" tab. Here you can see the degree of RAM load, as well as disable various background tasks.

Computer diagnostics

The optimal indicator of RAM use is not more than 5%, provided that all applications are closed. If the system shows a higher value, then it most likely contains a malicious process that consumes computer resources. Because of this, applications and games may experience lags, crashes, and FPS subsidence. To troubleshoot, it will be enough to disable background tasks that consume RAM.

Scan the OS for viruses

In some cases, it is not possible to get rid of the malicious process or it opens immediately after the administrator removes the task. Such a situation indicates the presence of viruses on the computer, which can simply consume the device’s resources or even transfer personal user data to third parties. Only an experienced specialist can cope with malicious program codes manually, and antiviruses are provided for ordinary users.

Virus in program code

You can download and install an antivirus program via the Internet. As a rule, the demo version is absolutely free, but after a certain time you will have to pay the company a certain amount (from 150 to 300 rubles per month) in order to continue to use its services. Anti-virus will help you scan the entire system for malicious program codes, after which it will completely remove them from the computer without touching the files you need.

Insufficient RAM consumption

In some cases, the reason for the loss of performance during the game will be the lack of RAM. If the product is fully suitable for your hardware according to all system requirements, however, FPS still drops dramatically during a huge number of special effects on the screen, then we strongly recommend checking how much the CPU and graphics editor consume RAM. To do this is extremely simple:

  1. Right-click on the "My Computer" label.
  2. Go to the "System" and "Advanced Settings" tab.
  3. In the window that opens, select the item "Performance" and "Change."
Computer RAM

Most likely, the initial size of the consumed "RAM" is in the region of 50% of the available resource. You must change this parameter to the maximum. That is, if the computer has two gigabytes of RAM, then the processor will consume only 1024 megabytes. To change this setting, you must enter a new value (2048) in the input field "Maximum RAM size". After that, game performance should increase by about 50%.

Graphics Card Drivers Too Old

Wondering why the FPS is sinking in Tanks (WoT) or some single player game? The reason may lie in older drivers for the graphics adapter. In most cases, the company that manufactures video cards warns its customers about updates, but in the case of a constant lack of Internet on the computer, the drivers may not be updated for years, which becomes a reason for crashes and lags even in old games.

Video card from nVidia

To fix the problem, you need to go to the website of the company that manufactures the graphics device (nVidia or Radeon), then go to the drivers section and download the archive suitable for your computer. If you do not know the name of your graphic device, then you can find out using the device manager by going to the "Video Adapters" section. Well, or you can download a special application that will detect this automatically.

Computer optimization using software

CCleaner for Windows

Also, do not forget about the possibility of optimizing your computer using special programs, which contain a huge number of useful functions. Here is just a small list of such tools that you can download for free:

  • Advanced System Care;
  • Aus Logics Boost Speed;
  • CCleaner and so on.

Using such programs, you can scan the system for performance and identify errors that interfere with normal operation. For example, quite often the load of RAM is caused by a clogged cache. The program will not only fix the problem, but will also monitor this indicator in the future.

Conclusion

We hope our article helped you understand why FPS is sinking in modern games. Of course, one could also mention the possibility of mechanical cleaning of the computer (due to dust, the CPU and RAM cooling system may not work well) or changing the graphics in the game to a lower one. However, such things are quite logical even for novice users. Therefore, monitor the state of the operating system and do not download doubtful files on the Internet. Otherwise, you risk not only losing precious FPS, but also passwords from bank accounts, credit cards and social network accounts.
