Question / Help Lagged frames (41%)

[BlueH2O]

I've been streaming live football games for two seasons using different Mac laptops on the same solid wired Internet connection, and I'm getting wildly different results that don't necessarily make sense (to me anyway). I've attached screen shots of each of the laptop's specs and I've included log files for each stream. Please let me know if you can explain the results I am getting and particularly why the newest laptop performed the worst:

First laptop log file is dated 8/10/18. This laptop produced the best results:

Second laptop log file is dated 9/7/18. Ignore the pink color tone. This post is more about the smoothness of the video:

Third laptop log file is dated 9/14/18 and this laptop produced the worst results (41% lagged frames):

Thanks in advance for your help :-)

Your GPU is overloaded in that last log. That's the laptop with only the integrated GPU, and it is significantly overloaded.

Not really sure what your question is? You've got two laptops with completely different GPUs (one with discrete Nvidia, the other only with Intel) and you're getting different performance on them, which makes sense.

Hey Narcogen!

Thanks so much for taking the time to respond. And you answered my question because you clearly know more about GPUs than I do. I was confused because I assumed "latest and greatest" meant best performance and that's clearly not the case.

All that being said, would a laptop with the same graphics card (Nvidia GForce 650M) with less VRAM (512MB instead of 1024MB) make a huge difference in the lagged frames situation?

Thanks again for your reply!
