I've been having issue streaming console games when streaming with the El Gato HD60. Whenever I stream the image becomes very laggy/choppy. According to OBS I am not dropping any frames (obviously untrue). I used to stream with no problem using an older Roxio HD capture device but have since upgraded to the El Gato HD60.

I usually stream at 720p with 3000 bit rate. I am 100% certain that Internet is not the issue as I have 100 down/up. This leads me to believe it is either my PC not being capable of streaming in this quality with this device or my settings are messed up.

Here are my PC specs Here are my PC specs:

I have an Nvidia GeForce 745m graphics card.

Is my computer not capable of streaming in this quality at this bit rate with this device?

Nothing changes, I used to stream in 3500 with my old capture device just fine. OBS just drops to random FPS with no frames dropped and randomly freezes.

"Just fine" is subjective, especially given that it causes viewer buffering if you don't have partnership and transcoding, which alienates a large portion of your potential viewers.

No frame drops is meaningless in that case.

It could simply be that the version of the elgato software and drivers you have is junk.

All your captures are super-short, instead of a minimum 5 minute capture like I always recommend. Pretending that the above is representative of the performance you're getting, this is terrible. 60% duplicated frames.

Most of the lag is from here:
17:03:46: | scene->Preprocess - [46%] [avg time: 3.426 ms]
17:03:46: | GPU download and conversion - [23%] [avg time: 1.709 ms] [children: 6.3%] [unaccounted: 16.7%]

Unfortunately I don't know what this actually means. I'm guessing a slow GPU for the second line. Not sure if Preprocess is your capture card or the CPU.

The best thing you can do is to change your preset to UltraFast. If you can update your GPU and Elgato drivers, you should do that too. If all that doesn't work, you should lower your fps to 20 or 15, and lower your output resolution (increase downscale). And if it still duplicates a ton of frames, then your laptop is just too slow for streaming.
