AV Famicom + Pinnacle 500-PCI (Bendino V1.0A) + OBS Studio = ?

Quick test of capturing video from my AV Famicom on a Pinnacle 500-PCI with upscaling to FullHD in OBS Studio. The sound is all wrong since it's a Line-In which is (I think) a driver bug that appears when you have more than 2GB of RAM. Will investigate further...

UPDATE 1

It seems that the driver bug can be removed by reinstalling the driver after each change of the settings (as that causes the huge lag). After disabling almost everything I found out that you can run the device without almost any input lag (it's so subtle that the average retro gamer without a CRT won't notice it]. Problem is that you get a bunch of on-screen glitches like the missing numbers on power-ups in Gun-Nac.

UPDATE 2

Also sucks at configuring OBS so this video is without any sound. But it was extremely out of sync anyway...

UPDATE 3

Seems like the delay is around 500ms. Offseting the sound in OBS Studio helped. All seems well now. I will post a new video with proper gameplay and how to set it all up when my new cables arrive.
