Glitching Video Capture Device

[Shadow64]

I use OBS with an Elgato HD60, and normally there’s no issues. However, when using a HD adapter for my old consoles, it causes the game feed to freeze briefly in multiple places then eventually skip a portion to catch up. An example of this can be seen in this video (Timestamp is the catch up, very start is the freezing): https://youtu.be/UEGX7skEaLc?t=1m6s
Is there a known fix for this?

The eon Super64 is one of the highest rated upscalers of all time, are u certain it’d cause issues?
