    Uh, if you have sync to VBLANK turned on then the frame rate will match your monitor refresh rate. That's what it's supposed to do.

    Here's the little monster, in action... LoL!

    The heat pipes (and 80mm case fan) make it run a LOT cooler than the OEM reference fan.

    Maybe that's the difference!?!?

    I live in Arizona -- need all the cooling I can get!

    Re: "New" OpenGL settings: Potential improvement vs. performance decrease - Worth it?

    Just to clarify things, I mentioned disabling "Sync to VBlank" because:

    - With Sync to VBlank enabled, glxgears will always report the monitor refresh rate (≃60). Disabling it naturally provides a higher FPS, which is a normal and expected result.

    - Therefore it would be impossible to see any increase/decrease in the results of glxgears when enabling/disabling the *new* options in CCSM without first disabling Sync to VBlank.

    - Disabling Sync caused some tearing and artifacts in the past for some users / cards. It seems like we can disable it now and still have a better and probably tearing free experience, if some of the other options are enabled. Right now, I don't see a need to enable VSync when playing HD content via 3 simultaneous instances of xbmc (using Buffer Swapping).

    - But, on the other hand, enabling all the mentioned options (as is the default when Ubuntu is installed) creates a significant impact in performance (responsiveness of the Dash and desktop windows, glxgears, gtkperf) and provides no benefits I could notice.

    Considering these settings are not accessible by ordinary users and are enabled by default (so far in the development process): Does it really make sense to have them all enabled in Quantal Release?

    Right now it doesn't look like that to me. Let's take under consideration that many early adopters already complain about the Unity DE and Dash being heavy on resources and slow. We will see that multiply after release. Whatever we can do to improve that experience should be considered now.

    Regards,
    Effenberg

    Those options do seem to have different results if disabled, in whole or part depending on hardware & possibly driver in use.
    (at least here vsync option in compiz is irrelevant, have absolutely no tearing here with vsync enabled in driver & the 'Always use buffer swapping' in a Unity session

    So on a 8400m, nouveau, any Actual gain in use by disabling those options is far out weighed by video display issues inc. mentioned window deco remaining on screen for a moment when moving window quickly & other possible bad behavior, alot related to Dash & blur options
    (currently all 3 blur options have faults, active blur is the least affected

    Maybe having those options enabled as a default is necessary because of llvmpipe?

    Not 100% sure but at least here the 1st.indication of slightly reduced overall perf (in actual use), came after the GLES branch merge in compiz, seen here (note the extensive changes
    http://bazaar.launchpad.net/~ubuntu-.../revision/3277

    Taking a look at one file you can see those 3 added
    http://bazaar.launchpad.net/~ubuntu-.../opengl.xml.in

    Again here there has been some improvement from before with the most recent compiz upgrade (on a fresh daily from post beta2

    Agreed!

    Look, I consider myself to be an "ordinary user", in a lot of ways.

    Right now, I'm watching...
    • The "First Presidential Debate" live, so called
    • Playing a Deadmau5 video, on my YouTube channel
    • Listening to an Alex Jones Podcast in Banshee

    Just "ordinary" activities...




    I don't have any tearing, artifacts, lagginess... nothing. No audio/video display issues. Everything is working like a charm!

    IMO, it's a big mistake having all that stuff enabled! In order to what?!?!? Have a transparent Dash? A paisley password box?

    It pulls the whole system down...

    @VinDSL, what icon theme are you using ? That seems cool.

    Re: "New" OpenGL settings: Potential improvement vs. performance decrease - Worth it?

    I'll note performance is a funny thing -- sometimes changing options to have something feel faster actually makes it slower (but what do you care, it feels faster right?). The sync to vblank is an obvious one for any gamer. Turn it off first thing.. If your a hardcore gamer though, instead you buy a nice card, 120hz monitor, and turn it on. It's critical for proper gameplay

    The unity team described the changes as a meeting in the middle. For some performance would be worse, others it would be better. But overall, it would be predictable and "correct". And they valued that over any small performance loss.
