I just wonder if there is something that I am not doing that I should be doing because out of the dozen or so HTPC that I have built locally here for friends (and check up on on a routine basis) I have never had anyone complain that it wasn't "smooth".
I just moved from a GT 545 to a GTS 450 on my main HTPC which is an i3 Clarkdsale, intel mainboard and intel SSD. Now I moved a Ceton out of my HTPC and put it in a dedicated Sandy Bridge. I can tell you the PC now does video much more smoothly, is it because the Ceton is off the bus, is it because the GTS 450 does the deinterlacing better.. and decodes faster I don't know, maybe all of the above. What I did not expect is that Live Digital Cable TV looks much more like it is was off my Tivo than what my Ceton has looked like. I believe that PC is using Cyberlink PD DVD 10 with Hardware deinterlacing.. Noticeably smoother. In JR Rvier I was watching one of my most challening MKVs.. from a DVD that the bit flags for film, movie are wrong. Anway, while the GTS 450 running LAV CUVID still gets the cadence wrong I am amazed at how much smoother it plays even playing it wrong. I have only ever seen one set top box get it right, clever deinterlacer in that one. My Iscan DUO can't get it right. I have the high end Toshiba HD DVD on a shelf somewhere, it could get it right, if you set it to film mode.... most even when set to a manual mode would jump to the wrong mode, I guess reading the flags.. definitely torture test. Lots of edges on bias to create a mess. Love the content though... between the bad edits, the wrongs flag and a color pallette that is super easy to turn muddy... it goes from totally unwatchable with poor playback to tolerable when it is done very well. It looks good on the GTS 450 with madVR.. Too bad LAV CUVID can't make sense out of the cadence and the flags either... still, it is the best I have ever seen it rendered off a PC.
I have to verify levels with the new GPU as they seem a bit off now, but it is just smoother, oh and it does madVR clearly better because I can make out lots of detail in test source material that I am very familiar. Text like lyrics on papers in front of musicians was readable for the first time in certain scenes. That was more than the subjective thing. Lots of little details that were previously not idenitfiable were clear as a bell.
I don't know the why's I can only report the observances. I really like the GT 545 as it was a quiet single slot Nvidia solution and the video looked much nicer than a GT 430 did running madVR in this same box.
So I started off with the Clarksdale iGPU then discovered madVR and moved to Nvidia. Don't get me wrong the Intel ideo has a nice look to it, it can't handle madVR and while a pain in some ways because it is not appliacable to WMC just produces video in another class from EVR. My display is pretty big, so improvements show.
Anway, I think the GTS 450 is as powerful a GPU as I am willing to go to at this time in an HTPC because I think the powerconsumption, noise and cost requirements for the more powerful GPUs start to reach the diminishing returns point for HTPC. I got the GTS 450 for $89. I was quite surprised that the EVGA GTS 450 was actually quieter than the EVGA GT 545. All in all it was a nice upgrade and I have a very good home in another HTPC client for the GT 545.
