If you want to run an assist script while playing at the same time, or you simply want to watch your bot work in the original GW2 client, the attach mode is what you need.
In attach mode, gw2cc acts as a sort of private server for the original GW2 client. Furthermore, UI elements or even 3D graphics can be overlayed onto the original game. For instance, it is possible to use gw2cc as an ESP with this.
Starting the attach mode #
Start gw2cc, select your account and hit the button “Attached”. Make sure that the account data entered in gw2cc is valid as gw2cc will be the one connecting to the official servers!
The first time gw2cc will now ask you where your Gw2-64.exe is located. If you symlinked the Gw2.dat make sure to select the very same exe!
Make sure to choose reasonably unique values for the “Computer Name” and “Computer User Name” fields as those will be used to spoof the unique HWID for your machine!
From here on out just proceed as normal. You can move the gw2cc settings menu by holding down the right mouse button and dragging it to where you want.
Black/White Screen #
If you only see a black or white screen after the bot selection first try to disable “layered on DXGI Swapchain” in your GPU driver settings. For NVidia cards you can do this by setting “Vulkan/OpenGL present method” to “prefer native”
AMD should have a similar setting.
In case your system is using NvIdia Optimus, AMD XConnect or Intel Switchable Graphics you can also try to disable it and force your system to only use the dedicated GPU:
If this doesn’t help try to change the rendering backend. Some GPU and driver combinations do not support Vulkan transparency for Windows. Simply open the settings (cog wheel), go over to “Graphics” and under renderer switch between Vulkan and OpenGL3.
After saving gw2cc will now restart to start with the new renderer. The setting will persist for all subsequent launches. If you have a blackscreen with both Vulkan and OpenGL please make sure that your Monitor is plugged into your GPU and not your on board graphics. You can also try to start gw2cc with ‘–gpu-index 1’. Please note that GPU index only works with the Vulkan renderer. If you successfully applied the command line you should see the following line in the log.
Note the “Using Vulkan Device #1”. Another option is to downgrade your GPU driver to one pre September 2023 which is where both AMD and Nvidia broke Vulkan transparency.
