nvidia 6200tc tearing and high xorg cpu usage seemingly fixed

Ever since my first "HDTV Success" post:
http://www.gossamer-threads.com/lists/mythtv/users/236498#236498

during Thanksgiving, I have kept myself busy tweaking. My post was a
bit premature because I didn't know what real "tearing" was until I
got some serious HD viewing hours under my belt. Since then, I've been
suffering with tearing of the picture. But, thanks to this post:
http://www.gossamer-threads.com/lists/mythtv/users/242086#242086

I am all happy now. Really. :)

I had been struggling with high xorg CPU usage when vertical sync was
turned on in nvidia-settings. So, I turned it off and resorted to RTC
syncing, which produced tearing.

I then added "UseEvents" "True" To my xorg.conf, turned on vertical
sync for xv in nvidia-settings, and voila, low xorg CPU usage, no
tearing, and just a beautiful, rock-steady HD picture with Bob
deinterlace on. mythfrontend now consumes between 40-70% CPU when
playing back HD streams, depending on bitrate and complexity.

NOW, I am happy. This thing is rocking.

So, for search fodder:
Tearing without using a 5200-based nvidia card was a problem (I am
using a 6200TC).
Added UseEvents with the 9629 driver and turned on sync and I am happy.

Mark

ack! can't wait to get home from "visiting the family vacation" to try this!

Do you have both XV VSync Options checked in nvidia-settings?
(Texture and Blitter) or just one or the other? Thanks. I'm really
hoping this will fix my problems with tearing with my 6200TC.

Wow. My fx-55 has been struggling with hd video for a couple of
months now. I had been considering throwing a dual-core at it, but
with this little 'fix' my cpu usage is down to 45% when watching 720p.
Awesome.

Thanks for the tip!

No, just "Video Texture Adaptor" "Sync to Vblank". Blitter is not checked.
In OpenGL settings, Sync to VBlank is off.

Well, I found the time yesterday (in the drunken hangover haze that is
New Years day...) between the Rose Parade (horrible horrible coverage
this year =( and the plethora of college football to upgrade to the
9xxx series drivers and apply the "UseEvents" option.

WHOOPEE!!! tear-free low CPU use 1080p playback! I even have Kernel
enabled as my deinterlacer and was able to get through some of the
higher movement scenes in The Two Towers 1080i without ever hitting
100% CPU usage on my Athlon64 3200+ (slightly overclocked, something I
am now playing with...).

I'd say overall this driver upgrade is a great improvement for folks
with HDTV capable frontends, I'd recommend at least trying it even if
you don't have any issues with the old 8xxx series.

Re: nvidia 6200tc tearing and high xorg cpu usage seemingly fixed [In reply to]

Steve:

I have this "tearing" issue on 1280x720p wth the same hardware you use
(A64, 3400+, "slightly overclocked", nVidia 6200-based video card).

I've been running the 8774 driver. When I installed the latest 9xxx
driver, the tearing in the upper area of the screen went away - just as
you mentioned...I was happy. However, MythWeb began to crash the system
when I clicked on "Backend Status" (it locked up X; I could ssh in but
couldn't kill the process, or even reboot cleanly - had to resort to the
reset button). The rest of MythWeb worked OK. This went away when I
downgraded back to the 8774 driver (but of course, the tearing came back,
and it's beginning to annoy me again). Anyone else seen this issue?

I suppose I'll wait for the next nVidia driver to see if this clears up.

Bob

Which 9xxx version did you use? I've had good luck with 9629 and 9631,
not so much with 9746.

I'd agree with Tom, try one of the older releases. I happen to be
using 9746 but I have a separate backend that I run mythweb on so I
haven't had to encounter this problem yet.

Re: nvidia 6200tc tearing and high xorg cpu usage seemingly fixed [In reply to]

Tried 9746 and 9631; both have crashed X. 8774 doesn't but playback is
better with the 9xxx drivers.

I suppose I'll have to avoid using the "Backend Status" page in Mythweb
until a driver comes out that doesn't do this OR the bug is fixed.

I will go ahead and report this bug.
