First thing I've learned is 48-60fps streams is a huge flailing nope on many devices and even my secondary desktop. It just uses way too much cpu to render the video and frames go POOF and then black screen
Edit: Also watching the hitbox stream in fullscreen also tends to use a little more cpu
You can get away with ultrafast encodeing if you upload at higher bandwidth. The Inverse is also true I got decent quality video 1280x720 30fps @512kb/s as well
so
1280x720 30fps @512kb/s with x264 cpu preset at (slow)
1280x720 30fps @3500kb/s with x264 cpu preset at (ultrafast)
Both looked about the same with the 512kb/s test being only slightly lesser in quality but not by much.
Anyways... I suppose a nice in between those 2 extremes is where I want to be at so I am curious of everyone's download speed, whether the device that watches streams has data caps and what cpu you have and at what speed it is at.
Here are my stats so far since this may be useful to others who stream in the future.
Streaming computer's CPU AMD Phenom II x4 20 @3200Mhz (4cores)
Secondary desktop's CPU AMD Athlon 64 x2 3800+ @2000Mhz (2cores)
I am mostly interested in download speed this website works well for me so if you use it copy the download speed it gives you. Chooseing the server closest too you is generally better.
