顯卡故障排除
本條目旨在解決因顯卡而生的各種故障問題。
遊戲無法啟動
這種情況可分為兩類，其一為舊電腦（2015年前）玩家，其二為新電腦玩家。
舊電腦玩家
一般來說，您只需要強制使用OpenGL 1.x，就能正常啟動遊戲。要更改OpenGL，首先您需確保電腦沒有運行DDNet客戶端，然後編輯位於配置目錄里的配置文件settings_ddnet.cfg，在文件底部添加：
gfx_gl_major 1 gfx_backend opengl
Steam用戶也可以在Steam中修改遊戲啟動選項（打開Steam庫，右鍵點擊遊戲並選擇「屬性…」，在「通用」選項卡下，您會看到「啟動選項」），輸入"gfx_gl_major 1; gfx_backend opengl"（謹記打上""）。
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
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
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.
