Joe, do you know at what temperature the cards will clock down?
I have recently upgraded my main mythtv machine it's a frontend/backend
combo. Used to be an AMD x2 and I upgraded it to a full blown Intel Xeon
server (Supermicro X9SRA). I am using the same GT 430 graphics card as I
had in the old machine. I used to be able to use the High Quality Nvidia
VDPAU without any problems. I had smooth video no matter what the broadcast
with Adv 2x with a Adv 1x fallback (never tried 1080p). However, now when I
try to use any VDPAU even without deinterlacing filters the video is a lot
of push-pull/slow-go to the point of being annoying. It's especially
noticeable when there's a smooth pan happening in the video or if someone
is walking across the screen. I'm currently doing all the decoding on the
Xeon processor instead of using VDPAU because of this. I still need to try
BTW: thanks Nick for that nvidia-settings command, pretty cool that we can
check the temps on these cards.
