FIXED: Delay in SDI output

Hi,

Have been using TD as a Character Generator using Blackmagic Extreme 4K card to generate SDI (1080i) fill and key for external keying with good results for several months now, recently updated my TD 088 from build 32840 to latest 62070, there is now a delay of 3 to 4 seconds on the SDI output! updated Decklink drivers to 10.8.3 but the problem still persists. Rolled back to build 32840 and it works fine again. Tried 60880 which i had downloaded sometime back, even that gives the delay in the SDI output. Any solution?

Here are the system details:
i7 3Ghz
32 GB Ram
Nividia 750i display
Windows 8.1 64 bit.
Decklink Extreme 4k,
Using both SDI outputs (8 bit fill & 8 bit key) @1080i 50

(on moving opacity of node level1, the output seen on SDI monitor updates with a delay of at least 3 to 4 seconds, however with 1080p it seems to work fine)

Thanks in advance.

This bug is now fixed. It can also be avoided by setting TouchDesigner’s FPS to 50 in the bottom left of the window.
