GFX Troubleshooting/zh

本条目旨在解决因显卡而生的各种故障问题。

游戏无法启动

这种情况可分为两类，其一为旧电脑（2015年前）玩家，其二为新电脑玩家。

旧电脑玩家

一般来说，您只需要强制使用OpenGL 1.x，就能正常启动游戏。要更改OpenGL，首先您需确保电脑没有运行DDNet客户端，然后编辑位于配置目录里的配置文件settings_ddnet.cfg，在文件底部添加：

 gfx_gl_major 1
gfx_backend opengl

Steam用户也可以在Steam中修改游戏启动选项（打开Steam库，右键点击游戏并选择“属性…”，在“通用”选项卡下，您会看到“启动选项”），输入"gfx_gl_major 1; gfx_backend opengl"（谨记打上""）。

If all this still does not help, you can still fallback to software rendering. Software rendering means it runs all graphics calls on your CPU instead of your GPU. This results in far less FPS, but might still be playable with some tweaks. Grab the latest 64-bit version of ddnet from https://ddnet.org/downloads. Now download and install 7-Zip. Download the latest mesa for windows from https://github.com/pal1000/mesa-dist-win/releases which should be named like this: mesa3d-xx.y.z-release-mingw.7z. Unpack the DDNet client somewhere, unpack mesa. From mesa move all .dll files from the x64 directory inside the DDNet client’s directory. So all .dll files are next to DDNet.exe. If you did everything right it should start the client again, if not try to add

gfx_backend Vulkan

to the settings_ddnet.cfg as described above

For users with new computers

Usually this is caused by bad drivers. You should check the manufacturers website for the newest drivers (AMD, NVIDIA, Intel). For Intel also note this article: Warning: Installing This Graphics Driver From Intel May Overwrite Customizations From Your Computer Manufacturer (OEM). If it’s still crashing you should try to use vulkan Do this by editing settings_ddnet.cfg that is located inside the config directory (FAQ#Where_is_the_DDNet_config,_config_directory_or_save_directory? Make sure no DDNet Client is running (best is you even check in the taskmanager) To the bottom of this file add:

gfx_backend Vulkan

If you are a steam user, you can also pass it as steam start parameter by writing “gfx_backend Vulkan” (INCLUDING the “) (rightclick ddnet in steam, properties -> start arguments

Some text is invisible with the Vulkan backend

Vulkan graphics bug with missing text

Users with an AMD card reported this and it’s caused by AMD driver from 2021. Just visit and download a driver from march 2022 or newer from https://www.amd.com/en/support. If there is no driver from 2022 you should switch back to OpenGL, you sadly cannot use Vulkan then, inside the client just paste gfx_gl_major 3;gfx_gl_minor 3; gfx_backend opengl in the F1 console and restart the client.

Some text looks broken

Razer Cortex-Overlay makes text unreadable

Some users reported broken text, e.g. text that is unreadable as if the text was streetched. This is caused by external overlays. Most people with this problem reported they used the "Razer Cortex" overlay. Disabling/uninstalling fixed the problem.

The client randomly crashes with an Intel GPU

Usually DDNet has a strong fallback system for Intel GPUs on Windows as they often caused bugs with OpenGL 2.1+ If you have a recent Intel GPU you can simply switch to Vulkan in the graphic settings inside the client. Else type gfx_gl_major 2;gfx_gl_minor 0; gfx_backend opengl in the F1 console of the client and restart.

Absolutely nothing helps

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)) You can simply switch to OpenGL backend, see #Some text is invisible with the Vulkan backend. Else you have to accept to use an OpenGL 1.x backend as described in #For users with older computers. 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.

Some ingame tiles are invisible or look broken

You are probably an user with an old GPU, just see #For users with older computers for the solution.
