Rage Pro Lombard patch: graphic acceleration

updated 08:05 pm EDT, Tue June 11, 2002

 
", 0, 0);


MacNN reader Derek Miller notes that Mac OS X 10.1.5 adds support for Rage Pro graphics acceleration for Aqua and QuickTime, but says it omitted Rage LT Pro chips (stock in some PowerBooks, such as the Lombard, and available on the ATI XClaim 3D Plus PCI card). He notes that James Denton has created a patch that enables Rage LT Pro acceleration: the Rage Pro Lombard patch. [URL updated]

"I can testify that it works not only on Lombards, but on my beige G3 with two LT Pro PCI cards. Aqua and QuickTime are both faster. QuickTime under Mac OS X 10.1.5 is now smooth even at full-screen -- while on my stock Rage II+ chip (and before Denton's update on the LT Pros as well) it remains choppy and unusable."

    couple of exceptions

    I installed this on my lombard. It did seem to work to some degree. I believe that Apple may not have released this because there are problems with dual displays.

    In addition, I had problems filling out this form in IE. Weird but I could not select the text area.

    Overall though, it did feel faster. Scrolling in IE seemed faster, etc.

    backup? openGL?

    is there a way to backup or undo the effects of this patch? is openGL supported once and for all? i can't imagine that this little graphics card can't handle the fading image screensaver...

    backup? openGL?

    Backup, yes (from what I understand reading stuff on line, people seem to have no trouble restoring things). OpenGL, no. Its 2D acceleration, not 3D acceleration.

    Link is down

    Apple.com link is down due to excessive bandwidth. Anywhere else to get this thing?

    Apple Owns Your Bandwidth

    First of all, I don't know why anyone would post their files/info/etc on the Apple site anymore - the bandwidth issue always kicks in...

    Secondly, it's sick how much faster video is with this patch. (Try Quicktime before and after at larger sizes - you'll see.)

    A few quirks (changing resolution requires a restart), but worth a try...

    Awesome.

    It worked great for me...I had a 7mb Quicktime video that I compressed myself from FCP, and it just wouldn't play at anything more than one frame every two seconds. I probably screwed up some setting when I did it. Now, though, it plays through with no problem!

    Tried it

    10.1.5 helped performance a little by itself... IF I dropped to Thousands. This patch helps a little more, in either Thousaands or Millions (Thousands still much better), but mainly for window dragging, which isn't a big issue for me anyway. Scrolling in particular is pretty poor, in browsers, Finder, etc. Still, a good tip to try! WARNING: changing color modes will black your computer out and force you to restart, so SAVE FIRST. And I got my first Kernal Panic EVER a while after installing this. Maybe coincidence. (I'm guessing Rage Pro LT was disabled intentionally since perhaps it wasn't quite complete.)

    Also, Acrobat will no longer display CoolType, even though it shows it as active. Weird. And scrolling speed in Acrobat got TERRIBLE with 10.1.5 (or with this patch, not sure).

    One last note: in 10.1.4, iTunes fps finally matched what OS 9 put out. Not bad! With 10.1.5 iTunes is again dog-slow. This patch did not change that.

    Apple's 10.1.5 notes should have made clear which machines were getting added support. Maybe Lombard will be added officially in 10.1.6... maybe even for OpenGL....

    Rage Mobility

    What about the Rage Mobility used in the first iBooks? Any chance Apple will support that soon?
