That is one thing that surprised me about my newer capture card. The
software that comes with it has no option to turn off the buffer so it
makes the games unplayable. But using alternative software bypasses
that and makes it perfect again.

But both of the old analog ones I had took care of turning the analog
signal into a digital stream. No compression, but that also means
nothing needs to be decoded. In fact, I think any capture card by
definition has to turn the analog into digital. It's the compression
that takes the extra power. If the capture card can directly hand off
the frames to the video output card then it doesn't take much CPU
power at all. The heavy lifting for simple live viewing is already
done by the capture card. If you want to do PVR stuff is the only
place you need more power. But neither one of them had any noticeable
delay. They worked wonderfully for any game playing.

And both of the analog cards I got were fairly old tech when I got
them years ago. They weren't all that much money even then.
