The Cost Of Running Compiz

[linuxforall]

hi folks

have a look here: http://www.tomshardware.com/reviews/...x,2634-11.html there are some more tests for this. Seems there is some major regresion on 10.04 either X or kernel. 8.04 wipes the floor with it with the same driver.

They used older mesa dri driver, adding x-swat ppa solves that issue. Lucid had a horrible memory leak with the newer mesa so they took that off but now that issue has been resolved.

My experiences with the recent (Late 2009 / early 2010) Catalyst releases, on a HD5970, agree with Michael's tests. In fact, I often find that everything -- 2D and 3D rendering -- is much, much faster with Compiz enabled than otherwise!

For instance, with Chrome (which does 2D rendering for normal text and such), scrolling the screen without compiz provides a very noticeable tearing effect and a "long" delay of about 0.25 - 0.5 seconds before the screen refreshes to display the new content. With compiz enabled, scrolling is as smooth in Chrome on Ubuntu as it is on a Mac Pro in Safari -- and we all know Apple has OCD when it comes to smooth scrolling.

I do indeed praise ATI for finally providing an optimized composited desktop. They still have some bugs to work out in the 3d driver, but it seems fglrx isn't the bogeyman it used to be. And yeah, they need to better keep up with Xorg and kernel releases

Still notice bad tearing when dragging windows on the desktop, but only when moving the window fast.

Aero does impair gaming performance as it disables itself on fullscreen. You can see this for yourself when you compare fullscreen to windowed. Case closed.

Aero is indeed very stable, but Linux is in constant development and deployement. Maybe Aero was considdered stable before Vista for all you know.

But... Windows has come a long way in terms of stability! Now they must focus, and they are with Windows 7, on speed and security improvement. With the legacy cruft and tools from the stonage it is inarguable that the people who coded key parts of Windows 7 are gods.

That doesn't take away that Linux is more awesome alround, though.

its common knowledge aero does nothing to game performance.

It was common knowledge for centuries that windows would pwn Linux in gaming performance till we saw Phoronix benchmarks few days ago.
I don't say you are wrong but common knowledge does prove nothing. Show me sources.

And aero also doesn't effect gaming performance like compiz.

Because aero is disabled then? Btw. Kwin is rock solid.

By what we saw in Phoronix benchmarks, Compiz+Catalyst doesn't affect gaming performance while Compiz+NVidia does. So it's an NVidia problem, not a Compiz one.
Also, we have not seen a windows test with aero enabled/disabled to say some things for sure. Do we?

Doesn't affect performance on ATi because AA/AF settings won't stick with compiz on.

Mainly crashes when running games that don't list windows vista or 7 as supported and OpenGL based games. I can assure you ram and video card are fine. A couple of times I have seen it crash with source based games. I have also seen it crash when minimizing games and alt-tabbing between a game and another application as well.

damn the 1 minute edit policy.
