Right now to save space on my computer as i only have 1.5 Tb left, i started streaming with OBS to Twitch where it can be stored on the internet.

Mostly i only stream 1 game, always the same Arma 2 Operation Arrowhead, the mod Dayz.
I´ve seen alot of streamers doing very nice videos with 1080p great details no problem streaming, so i wanted to do the same. I´ve kinda failed.

I know that i got the specc on my pc to do some nice detailed streamning, i just cant get it to work.

Here´s my internet data to the nearest broadcast center in Frankfurt, DE.

Followed by my pc speccs:
Windows 7 ultiamte SP 1 (64 bit )
CPU I7 920 @ 2.67Ghz
Ram 12 GB
SSD (64gb) for OBS and SSD(128gb) for the game (Arma)
Nvidia Geforce GTX 780 (MSI Lightning)

Can you please help me setup a setting that enables me to make videos with 1080p or atleast 720p with great details?, i dont need to have an active stream with followers, i want to stream, save the streamed video and then Publish it later after editing.

Heres a link to some videos of the same game in 1080p and 720p:

"Finely detailed 1080p video" and "streaming" do not mix. If you want good quality video, you'll have to do local recording only, and use high settings. If you want to save on hard drive space by streaming, you'll have to use lower quality settings.

That said, your current settings are kind of silly for streaming. For one, don't stream at 1080p60. Flash player is such a hog that it's nigh-impossible to watch on Twitch for anyone that doesn't have a beastly rig. Furthermore, since you're uploading to YouTube, it will be re-encoded to 30fps anyway, so you're spending bit rate on frames that will be thrown away. So drop back down to 30fps.

Second, that buffer is pretty absurd. Twitch requires that you use CBR, and setting a high buffer defeats that purpose. If you want to stream on Twitch, you should enable CBR, change your buffer to 3500 (or just remove the custom buffer entirely), and set a 2-second keyframe interval.
