3d acceleration causing dropped frames or stutter

[kny3twalker]

I have witnessed 3d acceleration do this on both of my systems
it is not a constant issue but there is a framed dropped at least once or twice during a half hour show

my laptop does it with FX 5200 and my desktop does it also with 9600XT

it seems to only happen in Sage, and furthermore overlay by itself seems fine


I have tried every decoder with no luck

furthermore when I use the TV out on my notebook
it works fine with VMR 9(3d acceleration has to be enabled)

but the LCD on the notebook still has the skips but they are not shown on the TV


this problem has been there for me ever since early beta with VMR9 and only in the later betas with 3d accleration when using overlay

but it is my belief that the issue is 3d acceleration

[kny3twalker]

wow I am the only one that 3d acceleration causes problems for
I am going to bug frey

[mlbdude]

VMR9 causes stutters for just about everyone. An ATI 9600+ is apparently not enough to do it smoothly. This is true for Any application outside of Sage as well.

I just ordered an nVidia 5700 to replace my 9600 as per the recommendation of users on AVSForums. I am doubtful it will work though. I will let you know.

Overlay by itself or with 3D Acceleration does not have any performance issues for me.

[kny3twalker]

huh it did not for a long time during the betas then I think it was the first RC that 3d acceleration just did poorly with random skips/stutters

yeah most software dvd programs tend to use VMR or overlay not VMR 9

I find one thing strange though I can watch a DVD with sage using VMR 9 an I do not remember the skipping

I will try to watch another DVD with VMR 9 and see if this happens

also I will turn off the biult in ATI driver overclocking(overdrive for XT models only)

I keep seeing the 9800 PROs for 200 or even 180, why not go with one of these rather than a 5700(I am guessing you got the non ultra, right) but it still cannot be that much less(I looked at the 5700 ultra when I got my XT and it was 20 dollars difference)

sales were PNY 5700 Ultra 170
and ATI 9600 XT 150
both were 50 mail ins

I went for the 5700 for specific technical reasons (supposed to have killer adaptive deinterlacing) seen on the AVSForums. Before picking that my specs were cheap as possible (jfor dedicated HTPC not my PC), quiet as possible, and cool as possible.

The one nock against the 5700 for me was the fan. I have a 5200 and was pretty unimpressed with the TV out performance of it compared to the 9600 so this may be a mistake.

From the forums people seems to be having lots of issues with ATI and VMR9 regardless of ATI card. Plus I wanted to try something new .

Say kny3twalker did try what [HUN]Adept post the other day on the shspvr forum about "The /pcilock parameter prevents the HAL from reallocating I/O and IRQ resources on the PCI bus. The I/O and memory resources set by the BIOS are preserved."?.

Let us know how the 5700 works out. Right now, I still can't seem to get a good picture that is clear enough for watching sports (I have a MSI FX5200) and I'm thinking it's because my video card isn't good enough. I've tried using different combinations of VMR, Overlay, Elecard, Sonic, ffdshow, VBR, and CBR and I still can't get a picture that is as clear and vibrant as my AIW 9000. So, hopefully it's just my video card, but maybe someone out here has a setting that will get sports to look just as good as watching sports OTA. Thanks and let me know how things go.

I will let you know. So far my best picture (night and day) is the 9600 with Overlay. However, I want my alpha-blended menu's .

Right, alpha-blended menu's is the primary reason why I want to stay away from ATI. At the moment, though, I have alpha-blended menus enabled on my AIW 9000 and it seems to work fine. It would be nice to start up a definitive hardware list on the forum somewhere...

[kny3twalker]

yeah it does just fine with DVDs
I may just have to try pcilock
but anyways it seems weird that the pvr250s are so easily distorted by anything

the production DVDs seem so much more stable

I watch last samuari and no one stutter or skip perfect playback when panning and everything

I just think it is weird when I use the same decoder setup (except just standard overlay) and it skips and stutters with my recorded TV

You may be on to something. Have you tried ReClick? Since a DVD is 23.xx fps and the recordings from TV are 29.xx fps it may have something to do with that.

Or since there are just fewer fps the decoder does not have to work as hard. Do you have a DVD that plays back at 29.xx fps to test with?

[kny3twalker]

I have no idea
how would I tell if the DVD has 29 fps?
I have tried reclock before just not recently
I will give it a shot again
I did use it in the past though

[mlbdude]

OK, I installed the 5700.

First the good news. VMR9 works completely smooth now. I will watch it closely over then next few days for sure.

Bad news, TV out video image with VMR9 is not as good as 9600 in Overlay. However, I think VMR9 is slightly better looking on the 5700 than the 9600. Overlay with 5700 is the worst of all.

So for now I have a slightly worse quality image with functioning VMR9. Lets see how long I can take it .

[kny3twalker]

I finally got one decoder to playback VMR 9 without stuttering
Elecard v2.2
it works awesome with overlay and VMR9 but the VMR9 picture is soft
and needs to be adjusted
but I think after this, it is a problem with the decoders are not being able to playback these recorded files well, doing VMR9

I just installed RC3 last night. I had been running 2.15 with good success, save a stuttering problem, which occurred every few minutes. I just tolerated figuring I would wait until I got the final release version installed.

Well the stuttering actually got worse and I have what I can best describe as motion blur. When there is even just a small amount of movement in the video, there is a "jumpiness" to the picture. I have never seen this before (I started with v1.3 way back when). I did turn off 3d acceleration and this did improve the situation significantly, all but eliminating stuttering. But the motion blur issue remains - though improved. I have tried both overlay mode and VMR9 with similar results. I am using the default video codec.

Anyone else have a similar experience?

[RoosterX]

I have tried 3 accel and wmr9, no problem like you describe here, only thing i didnt like was that the picture got a lot of brightness, i can probably tune it from within ati display properties overlay, but i like to keep it to std settings so overlay for now, even if it was nice bein able to see through menu's
GFX card is Ati radeon 9600xt on catalyst 4.5, and sagetv *client* 2.x eval, + elecard decoder rest of pc isnt so special so ill leave it out :P

PS. Stuttering occured when i did use PowerDVD's decoder.

[kny3twalker]

yeah elecard and intervideo seem to play back the best but give the worst quality
I like nvDVD,sonic, cyberlink but all cause skipping with 3d accel and/or VMR9
it seems to be the worst when panning

mlbdude,

I have a 5200 and seem to be running VMR9 OK. I would agree that I've seen better TVout. Can you compare the 5200 vs the 5700?

I was actually thinking about trying SHS's XCARD + VGA card with the 26 pin header as a solution, but the XCARD is $90.

5200 with VMR9 had tearing and lots of stuttering with Sonic or NVDVD. Elecard seems to work on any card fine. In fact, any decoder works fine for me in software more. With DXVA enabled only the Intervideo Hauppauge will work flawlessly in VMR9 on the 5200 or the 9600.

The 5700 has no tearing at all in VMR9. With NVDVD it has occasional stuttering but not bad. With Sonic it is perfect. VMR9 still looks like poop compared to Overlay, but the Alpha-Blended menus are too nice.

If you want PQ the 5200 in Overlay is just fine. I probably wasted my money and should have stuck with the 9600 in Overlay mode . The 5700 may go in the box next to the 5200 in the closet. We shall see.

[kny3twalker]

yeah the stuttering is not constant and I never get any teaing any more since early beta
but the fact that it stutters sucks
I hate it and it is so annoying
have you ever consider making an overlay freindly UI with studio mlbdude
I am still surprised though with playback more stable in older versions that Sage went gold already
but when Snapstream hits the stores what you going to do?
