MS Office Forum / General PowerPoint Questions / May 2008Hardware acceleration in 2007
I've had PPT 2007 installed on two very powerful laptops but find that hardware acceleration just doesn't work like it did in 2003. With HA enabled the result is the same on both computers: Problem #1: the object animations do not play out in the slide preview - everything just appears (but play correctly with HA off) Problem #2: when playing the slideshow HA has no affect on the speed whatsoever - and is sometimes even slower. Problem #3: all the object animations are slower with much faster computers in PPT 2007 than they were with slower computers in PPT 2003 It seems that MS has managed to just break the hardware acceleration function between versions. I can't be the only one who has this problem. Config: Dell XPS M1530 Intel Duo Core 2.4 4Gb RAM 256Mb video RAM 200Gb, 7200 RPM HD Vista Ultimate All updates installed for Vista and Office David, Do you have an embedded Intel display chip?

[quoted text clipped - 19 lines] > Vista Ultimate > All updates installed for Vista and Office If you mean integrated video, no - it has a dedicated Nvidia GeForce 8600 GT with 256Mb. The computer has an Intel Duo Core, but I don't know what the chip set is on the video card, but almost certainly isn't Intel, I wouldn't think. My previous computer, an Acer Ferrari with a dedicated 128Mb video card (Nvidia I think), and this one a Dell XPS M1530 are essentially high-end desktop replacements and quite powerful, with very good Vista graphics performance numbers. The Dell rates as 5.9 - way above the Acer. However, I never had this problem with PPT 2003 on significantly slower computers with only 64Mb video RAM. But with PPT 2007, the problem has been identical on these two much faster computers. Does PPT 2007 have a known issue with Nvidia drivers from Dell? I don't know if I can directly get drivers - as Dell tends to somehow require proprietary drivers for their implementation of video cards. It is frustrating to have to run with hardware acceleration off and go in and change every single "by letter" text animation to "all at once" - when it worked perfectly in PPT 2003. I don't understand how hardware acceleration actually degrades graphics performance.

This should tell you if the video card / driver is having a problem with any of the directx functions. (Run it twice with HA on and off.)

Has anyone else here seen the animations not work in PPT 2007 preview with hardware acceleration turned on? As I have mentioned, this has consistently been the case with PPT 2007 from its installation on two difference computers. > One more suggestion, try turning the Aero Glass feature off in Vista. > [quoted text clipped - 80 lines] >>>>>> Vista Ultimate >>>>>> All updates installed for Vista and Office > Makes no difference. > > Has anyone else here seen the animations not work in PPT 2007 preview with > hardware acceleration turned on?

They all play as they should for me (using an ATI video card and driver). The only thing else I can suggest is looking to see if there is an updated driver for your video card. SignatureAustin Myers Microsoft PowerPoint MVP Team Creator of PFCPro, PFCMedia and PFCExpress http://www.playsforcertain.com I had already looked for the latest driver and I had it installed. It must be the Nvidea / PPT 2007 combination - as I think my previous laptop also had an Nvidea card. It worked fine with PPT 2003, but never with 2007. Anyone else out there with Nvidea graphics who has this problem? It is really, really frustrating - to have one of the most powerful laptops on the market and have to live with jerky PowerPoint. I just can't do any letter by letter animations at all, whether it be fades, descends, expands or anything else. But it plays video as smooth as silk - including in PPT (which is not a surprise given how video is implemented in PPT). I have gone into the Nvidea control panel and changed a few options, but with no effect. I can't see anything obvious that it might be. I'm currently teaching a 20 class-hour course with about 800 slides in 10 separate files (yes the problem is still there with just one slide) and it is very mult-media intensive with lots of effects (not distracting), music, video, but attention-grabbing - which I have taught 4 previous times in PPT 2003 just fine and so this just drives me crazy. I'm also the director of our Tech. and IT Department - and I've been a "power-user" since PCs hit the market.
