What do you mean by don't expect great performance.? Is it a GLX issue or something related to this particular version of XWin, as compared to the older ones? Thanks a lot! Gustavo. Sorry for the delay in replying. I thought I'd sent it thanks to Outlook telling me I had, when in fact it had only saved it in my drafts folder! This isn't new, it was experimental at the time Xwin last had a maintainer and just never got promoted to stable. It's available through setup.exe, but I guess you have to tick the exp radio button at the top to see it (once it's installed, it appears without selecting exp). In terms of performance, GL software is really designed for running on the local host, so you're never going to get blazing performance running clients on a remote host. The network overhead slows it down considerably. However, XWin's GLX is not particularly fast, even when running locally. Running glxgears.exe at the default size, on XWin running on my laptop, I get (approximately): 62 fps running locally 31 fps running on a linux box without using ssh forwarding 21 fps running on a linux box via ssh forwarding without compression. 47 fps running on a linux box via ssh forwarding with compression. None of these are stunning (IIRC, I get several hundreds of fps on a linux box at home), but it may be adequate for your purposes. My experience is that native GL applications running on Windows (e.g. Blender3D) run noticeably faster when running full screen (if they can), because there is no contention with DirectX. I haven't tested it, but if performance is a problem, it may be worth trying XWin full screen before giving up on it. I haven't looked at the code, but the locally run glxgears runs at 100% cpu on my laptop, which suggests that much of the GL code is handled in software, rather than hardware accelerated. The remote tests all run at about 92% cpu, so the network is (just) the limiting factor.
