When I run glxgears under the latest X11 release, using rooted window
in fullscreen mode, I get a frame rate around 3200/sec, a rate
comparable with the rate I get with the same hardware running Linux
and native video drivers. Thats great news in terms of GLX
implementation.
However if I type ctrl-A to get out of the root window, and run
glxgears from the non-X11 Apple Terminal window, the glxgears window
pops up, visible in rootless mode. If I switch to X11.app and type
ctrl-A to get back to my root window, the running glxgears window is
no where to be seen. I have to ctrl-A again to the rootless window to
see it. I am wondering if it is that way by design, or a quirk of my
window manager or X11.
I also see a major difference in glxgears' frame rate between the
glxgears run from the root window, versus the one run from Apple's
Terminal and visible in the rootless window. This is expected of
course. I'm wondering if the drop in frame rate could be related to
the performance of the window manger as it handles its interface with
Xquartz, and also if it could be used as potential measure of how well
different wm's work in the Apple environment. Also wondering if the
glxgears frame rate comparisons are useful to developers.
