Hi all
I have been running a HD5450 in my HTPC for a while and its been good for TV and blu ray movies at 720p
but I just got a new 3D 1080p TV and when watching 3D the framerate is really bad and the sound occasionally stutters then gets out of sync.

Other times it was like it was alternating between running too slow and too fast. alternating every second or less.

  •  Generic LGA775 motherboard
  •  Dual Core E5200 @ 2.5Ghz
  •  Graphics card: HD5450 512mb
  •  2GB DDR2
  •  Windows 7 Home Premium SP1 - Running Windows Media Centre
  •  160GB 7200 8Mb Seagate sata hard drive (ST3160811AS)
  •  LG Optical Blu Ray drive

Maybe check your CPU usage while running it. That GPU doesn't do hardware MVC decoding so might be your CPU is the bottleneck.


EDIT: Interesting, what's with these newegg links?

Have you turned on dxva? and upgraded to the latest drivers?

Tried XBMC? Does it yield the same choppy playback as WMC?

sidefx: Maybe check your CPU usage while running it. That GPU doesn't do hardware MVC decoding so might be your CPU is the bottleneck.

CPU was averaging around 30% today, I checked it last night it definitely wasn't running at 100% or anything. see below about the GPU though, I made a mistake


regarding the links, that is kinda weird. I had heaps of links as well as I copied from my earlier thread http://www.geekzone.co.nz/forums.asp?forumId=84&topicId=105035
 the newegg one was from that. don't remember why I put a newegg link in that time... weird.

urban: Have you turned on dxva? and upgraded to the latest drivers?

I am using Arcsoft totalmedia theatre to play the discs, I cant find DXVA anywhere in there or in the graphics cards properties. yep, all drivers are upgraded.

and this is weird as. based on my last thread I said I got a ATI. I just looked at the computer again and realised its an Nvidia

I am a complete idiot. I actually have a NVIDIA 210 with 1GB http://www.pbtech.co.nz/index.php?z=p&p=VGAEVG1313 or http://www.geforce.com/hardware/desktop-gpus/geforce-210/specifications

It doesnt say anything about supporting DXVA or MVC

From the Nvidia website re Geforce 210
"Blu-ray 3D playback is enabled on CPU playback only on these GPUs" and it's not recommended for 3D.
Your cpu is rather low spec for 3D too.

Odd, something seems to be auto-inserting newegg links. Did it to me when I mentioned HTPC too... Anyway:



Even if the 210 doesn't do MVC, it should be ok if CPU can handle it and I think your one should do (it's dual core right?) - so if CPU is not bottlenecking then I suspect something else might be going on. Though yeah, 210 isn't exactly a powerhouse.

Cool, Thanks b1gglz! & sidefx

What do I need to look for in the replacement video card?
Is there some tech (dxva?) I can ensure it has so I don't need to worry about the CPU, or is that going to be a bottleneck regardless of how good the video card is

an HD7750 http://pricespy.co.nz/product.php?e=1161412  says it has Blu Ray 3d 'support' although I don't know if that means its good for it :/

I guess what I am really asking is; how much do I need to spend to completely resolve this?.

Well I think you need to find the root cause. It actually looks like the GT210 should do MVC and framepacking, so as I say above I think something else is going on. Here's a decent reference post:

BTW: What software are you using for playback?

arcsoft totalmedia theatre 6 

is there any benchmarking tools I can use to test it? I had to return all the 3d movies today

Have a look here for suitable cards.

In any case don't buy a nvidia 210 they are very crap. And they dont de-interlace 1080i properly. I've got a geforce640 and it dose a good job. 520 is probably OK. I think nvidia is best for HTPCs.

After struggling with this for ages I discovered the heatsink thermal paste had dried up, was bumpy, and was not working. The CPU was running hot, not over working, just hot (like 99 deg)

I put some toothpaste on it until I could go and buy some proper paste and immediately everything worked perfectly.

Today I put some real thermal paste on so now its resolved. crazy.
