Hopefully this will be a simple question to answer. I have an Avermedia Live Gamer HD and I use it to record my Xbox 360. I've used it for a while and have generally been happy with the performance, but I always noticed a slight fps drop every once in a while (every 5-10 seconds). Its pretty slight and most people wouldn't care, and I always thought my it was just an adobe flash issue in my browser, but its been bugging me lately, so I decided to dig into it a little deeper.
Before I did this unscientific test, I made sure to update the firmware and driver for the avermedia card. After that, I merely did a side by side viewing. I changed my first monitor to HDMI, to get a direct feed to the Xbox 360 video. I then turned on just the "preview" function of OBS (encoding disabled) and full screened it on my second monitor. Viewing them side by side, I could see the xbox maintained a smooth, constant frame rate, whereas the OBS preview had visible, slight frame rate drops every once in a while. These drops were purely visual however; OBS itself said that it was 60fps in the bottom right corner at all times. Even my recordings say 60fps when played back in media player classic. However, I'm assuming this fps is the rate the software is recording and has nothing to do with what the source is displaying.
Comparatively, I did another stream of a PC game using game capture (no capture card was involved), and the resulting stream had constant smoothness, and I could not see any dips like I did with footage recorded from the capture card.
Like I said, the performance is for the most part acceptable and most people would not even notice a problem, but its really bugging me how the HDMI output is completely smooth at all times, yet recordings and even preview mode in OBS show visual dips. I don't know if its a problem with the card, OBS, or some setting I have. Anyone have any ideas? I'll include a log and a screenshot of my Live Gamer settings in OBS. I can also upload a small recording and point out a spot where I see it. This could all be in my head as everything says its 60, but I wanted to ask to make sure.
