-
-### Q1. 对等连接失败
-**A:**  
-打开设置，勾选 **启用中继服务** 选项，尝试重新发起连接。

-
-由于公共中继服务器带宽较小，连接的清晰度流畅度可能会下降，建议自建服务器。 [Issue #8](https://github.com/kunkundi/crossdesk/issues/8)
-
-### Q2. Windows 无 CUDA 环境下编译
-**A:**  
-运行下面的命令安装 CUDA 编译环境。
-```
-xmake require -vy "cuda 12.6.3"
-```
-安装完成后执行
-```
-xmake require --info "cuda 12.6.3"
-```
-输出如下
-
-<img width="860" height="226" alt="Image" src="https://github.com/user-attachments/assets/999ac365-581a-4b9a-806e-05eb3e4cf44d" />
-
-根据上述输出获取到 CUDA 的安装目录，即 installdir 指向的位置。将 CUDA_PATH 加入系统环境变量，或在终端中输入 set CUDA_PATH=path_to_cuda_installdir，重新执行 xmake b -vy crossdesk 即可。
