==Low FPS, stuttering or similar problems == <!--T:25--> | |||
<!--T:26--> | |||
These problems can be caused by many things, most commonly stuttering is caused by a bad driver or overheating of some component. | |||
Here is a guide that can help eliminate these kind of problems: | |||
*Update all drivers, and the operating system to latest version. On Windows go in the Windows safe mode and uninstall the graphics driver using [https://www.guru3d.com/files-details/display-driver-uninstaller-download.html DDU] (not open source, please replace it with a similar tool) or similar tools and then install the latest driver from the manufacturer's website. This can fix more problems than you could guess | |||
*For Windows: restart Windows using the "Restart" button (not shutdown). This will clear some caches | |||
*Clean your computers coolers. Remove any kind of dust with some air pressure (better don't use a vacuum cleaner because of electric charges). Watch if temperatures of the hardware components are below their proclaimed threshold. | |||
*Make sure the hardware (e.g. the graphics card) is properly plugged in. | |||
*Try to lower the refresh rate in the client (cl_refresh_rate, gfx_refresh_rate). | |||
*For Windows: set Windows to high performance mode | |||
*Close all other software (e.g. Discord, Mouse/Keyboard tools) | |||
*Unplug all USB devices you don't need (USB sticks, controllers etc.) | |||
*Try a different renderer in the DDNet client. settings -> graphics -> renderer | |||

If you are sure you did everything correct and nothing helped report this bug on ddnet’s discord #bugs channel. You are the first encountering this situation. The only known modern GPU that caused problems is an AMD ryzen 3 2200g, if you don’t use the AMD beta drivers (confirmed with Adrenalin 22.5.1 Recommended (WHQL)) | If you are sure you did everything correct and nothing helped report this bug on ddnet’s discord #bugs channel.

You can simply switch to OpenGL backend, see [[Special:MyLanguage/#some-text is invisible with the vulkan backend|#Some text is invisible with the Vulkan backend]].

It’s also quite possible that the problem is not GFX related. Try to disable your Anti-Virus for DDNet, make sure you use a recent Windows/Linux/macOS version. Always try 64-bit versions first as they are more tested. | It’s also quite possible that the problem is not GFX related.
