"Idle" in this case means running "top -c" on a borderless, focused, and fully maximised terminal, with the "still" composite style, then just watching it for a while. So in this case, the composite does not have much to do, as anything running under the window should be irrelevant? In case it matters, I do run the clock, tclock, and cpufreq modules, as well as gkrellm, nothing else is updating. > > CPU: AMD Phenom(tm) II X4 840 Processor > > Memory: 3961 MB > > Graphics Card: GeForce GT 220/PCI/SSE2 > > OpenGL Version: 3.2.0 NVIDIA 195.36.24 > > > > Unloaded the module again. > > you enabled opengl AND texture-from-pixmap? i've had e comp working > silky smooth on a gf6600 with 3520x1200 of pixels. games pay the > price of another buffer copy - that's it. nb i did add some options > for nvidia's driver: > > Option "TripleBuffer" "True" > Option "Coolbits" "7" > Option "UseEvents" "True" > Option "OnDemandVBlankInterrupts" "True" Yes, openGL and texture from pixmap are both enabled. I have updated e17 just now, added those nVidia driver options, and tested again. The 3D virtual world viewer now runs smoothly again, and I'd have to do some careful tests to see if there is any difference in frame rate - in other words, no noticeable difference. Which means not enough difference for me to worry. I'm not a frame rate whore. lol In the "idle" test as mentioned above, it's now using 20 to 40% of one core, so that's better. Also, using twice as much ram as it was before. Ah, closing gkrellm drops composite E17's CPU usage to mostly 2% of one core, with peaks of up to 25%. So it DOES matter what's running under a non transparent window. I have the gkrellm stretched out to it's maximum size, which takes up about half the screen real estate. > wait a sec.. your nvidia drivers are ANCIENT... like from when > dinosaurs roamed the earth! get an update man! I run mostly stock current Ubuntu LTS for good reasons, and I wont update until some time after their next Long Term Stable release is out. And just in case people had not figured it out (surprising the number of people that get this wrong, but that should know better) the current Ubuntu LTS is 10.04, almost two years old, NOT 11.04. So the graphics driver I use is the standard Ubuntu LTS one, and I will not update it, unless Ubuntu push out an update. That's one of the things that's very important to me to keep stock LTS. I do run some bleeding edge stuff, like E17 for instance, but those things don't impact on my reasons for needing to use current Ubuntu LTS. Not sure if those nVidia driver options will stay, so I might test without them later. They go against the "keep it stock LTS dammit" grain. lol I'll do some more tests, but I think I can mostly live with it now, with the promise of better performance to come in E18. The virtual world stuff is of major importance, so anything impacting it's performance is a no no. I sometimes get paid to develop that stuff. Just for further info, I run six virtual desktops, on one monitor, at 1920x1080 24 bit. I stay well away from E17's fullscreen mode, think I've mentioned that enough over the years and why, using fully maximised borderless windows instead. For me, "fullscreen" just means it takes up all of the screen, NOT that I loose control and cannot switch to other windows. I really don't care what apps that want to take over control of my screen want to do, especially since most of those are buggy, I want complete control of my own computer. :-P -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
