Question / Help Pixelated Stream

[angelsg]

Good afternoon,

I have just upgraded my computer from a 1366 motherboard and a core i7 920, to a maximus vi hero and a 4770k. Currently stock speed as apparently my heatsink doesnt fit so just using the stock 1 for now, I am trying to stream at a decent FPS and quality.

core i7 4770k
maximus vi hero
16 gigs of 1600 ram
GTX 680
evo 840 SSD, obs is installed on that

speedtest.net is 57.97 mbps down, 38.87 up

I do have one of these :
http://www.newegg.com/Product/Product.a ... 6815100049

Is it even possible to use this for streaming PC games? My main use was to stream PS3 games.

Here is the log. I think this is my most recent using game capture, aero enabled, 4000 bitrate and buffer size, resolution is 1920x1080, downsacled to 720p, with lanczos, 45 fps.

Those settings should produce a pretty good-looking stream. Can you show an example video of where it looks pixelated?

Also, make sure you change your keyframe interval in Advanced settings to 2, which is what Twitch requires.
