通过 RDP 使用 OpenGL 着色器时使用哪种显卡? [英] Which graphics card is used when working with OpenGL shaders over RDP?

问题描述

我正在使用 Surface Pro 参加 OpenGL 开发入门课程，并希望通过本机 Windows 远程桌面工具连接到我更强大的桌面进行开发.我的第一个测试程序中的着色器有问题，这导致了我的问题.着色器工作将由我的 Surface(RDP 客户端)还是我的桌面(RDP 主机)上的显卡完成?

I'm taking an introductory OpenGL development course with a Surface Pro, and was hoping to connect to my more powerful desktop for development through the native Windows remote desktop tool. I'm having trouble with the shaders on my first test program, which leads to my question. Will the shader work be done by the graphics card on my Surface (RDP client) or my desktop (RDP host)?

推荐答案

这取决于远程系统的配置.您通常使用标准驱动程序的消费级 GPU 不会为 RDP 提供任何硬件加速，您将进入软件仿真模式.然而，有一些特殊的可视化服务器 GPU 和驱动程序可以连接到 RDP 服务器实现并为其提供 GPU 加速；不过很可能你没有.

That depends on your remote system's configuration. Your usual consumer GPU with standard drivers will not provide any HW acceleration for the RDP whatsoever and you'll drop into a SW emulation mode. However there are special visualization server GPUs and drivers which hook into the RDP server implementation and provide GPU acceleration for it; very likely you don't have that though.

请注意，这最终只是驱动程序问题.有了正确的驱动程序，每个 GPU 都可以做到这一点.但硬件供应商想要销售他们的专用设备，因此他们将功能锁定到特定产品线.

Note that it's ultimately just a driver issue. With the right drivers every GPU could do that. But HW vendors want to sell their special purpose devices, so they're locking that functionality to a specific product line.

我希望，在不久的将来，Linux 开源图形生态系统的进步将能够实现具有商品硬件的此类可视化服务器.尽管我无视 Wayland 协议和 condept，但我很喜欢它的发展促进了 Linux 图形堆栈的较低级别的进步.这可能会给 Windows 世界带来一些压力以赶上它.

I'm hoping, that the advances of the Linux open source graphics ecosystem will, as a sideshow, enable implementing such visualization servers with commodity hardware in the near future. As much as I disregard the Wayland protocol and condept, as much do I like the advances its development promotes toward the lower levels of the Linux graphics stack. Which may likely put some pressure on the Windows world to catch up with that.
