[Bug 987304] Re: [regression] [precise] 3D apps run much slower under Unity
Foremost, apologies if this is not the right thread to post my observations or if they have been previously mentioned. I have an nvidia board and use the proprietary drivers. Like in oneiric, 3D applications (e.g., glxspheres) do run well after a reboot however, after using a couple of compiz animations (wall, scale) performance drops considerably. Furthermore, 2D performance also drops in applications like Thunderbird, where scrolling in a long list of email headers is very choppy and results in high CPU usage. Recently, I discovered that just changing the screen refresh rate from nvidia-settings, back and forth between 50Hz and 60Hz, is enough to restore performance (including 2D). I noticed it because my screen's refresh rate is 60Hz however, by default, nvidia-settings reports it as 50Hz and refuses to remember my setting. I also manually set the refresh rate in CCSM at 60Hz.

[Bug 888039] Re: Gradual degradation in desktop performance.
Hi Daniel, As previously mentioned, despite using your ppa, I'm also getting the performance degradation. Unfortunately, the command you just posted does not restore the performance either. However, if I am to compare performance after degradation sets in, I think (no measurements though) that the interface is a bit more snappier after installing your fixes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/888039 Title: Gradual degradation in desktop performance.

[Bug 861061] Re: [regression] All apps have a lower frame rate under Unity.
Thanks! Just installed them both on my laptop with an Nvidia NVS 140M and a C2D T9300. First impressions: - I can also confirm the increase of the number of fps in glxspheres to ~140 just after logging in. This is identical to the results in gnome-shell. - No tearing when moving windows around Downsides: - Aggregate CPU usage of compiz, unity and X is constantly above 5% (3% compiz, 1% unity and more than 1% X). Gnome-shell typically uses just 1-2%. - After several minutes of using chrome, thunderbird and other applications, glxspheres frame rate dropped to 40-70fps. Other thoughts: - enabling of chrome flags GPU compositing on all pages and GPU Accelerated Canvas 2D has quite a detrimental effect on frame-rates. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861061 Title: [regression] All apps have a lower frame rate under Unity.

[Bug 888039] Re: Gradual degradation in desktop performance.
Well, at least we're two. I can reproduce this bug on my laptop with an Nvidia NVS 140M shortly after a restart. For me, the sluggishness/jerkiness never goes away. This might have to do with my card being a bit outdated. Same holds for bugs 861061 and 880707. So, I'm really looking forward to a compiz (and unity) fix Christmas present.

[Bug 629910] Re: nvidia 256.53 xorg-server 1.9.0 performance regression with antialiased text
So did the Nvidia 260.19.06 driver solve the issues for you? I've got an Nvidia Quadro 140M NVS, Maverick RC and 260.19.06-0ubuntu1 installed and I'm still seeing poor system performance (eg. scrolling or running a verbose script in gnome-terminal eats one of the cores of my CPU).

Re: [Bug 629910] Re: nvidia 256.53 xorg-server 1.9.0 performance regression with antialiased text
@ Magnus I also thought 260.19.06 solved the issues for me. For example, another 'common' regression which seemed to be solved was scrolling in Firefox (Chrome wasn't affected, at least not for me). But, what I didn't mention in my previous post is that for me this works only after a (re)start and only for a certain period of time (maybe it depends on the number of open applications). I'm not sure if this is the same problem as the one reported by eZFlow and Extender or something only I encountered. Nevertheless, it seldom happens to work properly and only under light system load. -- nvidia 256.53 xorg-server 1.9.0 performance regression with antialiased text https://bugs.launchpad.net/bugs/629910 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 595845] Re: libcairo2 1.9.10 makes Ubuntu 10.10 slow
I'm also experiencing these problems, and I'm speaking about high CPU usage due to xorg when scrolling in applications (eg. Firefox, terminator, pidgin and other). I'm using maverick beta with libcairo2 1.10.0 and nvidia-current 256.53 .
