 |
|
I am helping to setup a "new" system. The projector is a NEC PG9000 driven at 720p-72Hz. The PC is based on a Pentium D945 (2x3.4GHz) CPU with 2GB ram and ATI HD4650 (512MB) VGA card, running on a 32bit Win7 os. The blurays are on an external harddrive (WD Elements). And I was unable to get usable framerates neither with VLC nor with MPC. I have no experience with this video card but I think it should play HD movies fine on relatively weak CPUs and however this Pentium D is fairly old but should be quite capable. Any suggestion what am I missing?

Is there a "Use hardware Acceleration" check box in either video playback program?

I tried with Core AVC codec and DXVA acceleration in MPC, and the output wasn't statisfactory either. However statistics in MPC showed good framerates and minimal dropped frames, but the motion is unsmooth (regardless of hardware acceleration), not quite chopping, more like waving and slow, CPU was usage around 60-70%.

I don't believe 2 GB RAM will be enough to run Blu-Rays, even from a harddrive. That's a lot of data being transferred. And you have the overhead of the USB or other data network to squeeze in there as well. Bet the OS is making a huge swap file on the primary drive.

But none of the media players wants more than ~200MB ram according to Task manager, top of that there are plenty free ram, I think this is more like a codec setup problem, Next time I'll play with that.

OK. Microsoft's own minimum spec for Windows 7 32-bit is 1GB memory. Add the 200 MB the player needs and you're down to 800 MB free memory, even if nothing else is running in the background. The Windows site also says, "Depending on resolution, video playback may require additional memory and advanced graphics hardware". I still think there isn't enough RAM to give you smooth glitch-free playback.
