Question / Help Trying to get smooth 60fps / 480p

I have been messing around with QSV for playing fast paced games (namely CS:S surf) where having a smooth video output is almost required for it to look nice.

http://www.twitch.tv/lodyb/b/410175583 - I made sure nothing with gpu acceleration was running, i.e flash
notice I have like 600 fps in game, the game was butter smooth whilst recording this video.

I had no frame drops although I'll post my OBS log to show what settings I am using and my specs.

(I have no idea what half of this means)
I don't care about overall quality of the video, just that its smooth.
Any tips would be appreciated, thanks.

Here's the section with my PC specs, it was at the very top of the log.

Looked at the video and it's really pixelated.

Seems like it can't render properly.

What's your upload speed? When you tend to stream in 60fps, you need double the upload. I would try 30 and see how that looks tbh.

No, you don't need double upload.
Pixelation is expected when using QSV, especially on that resolution.
To be honest, I don't see whats wrong with that video, its all smooth to me. What exactly is your issue?

do x264 encoder settings + presets affect quick sync encoding
will increasing the resolution help with the blurriness/lossyness in the output
am i doing something dumb in my settings

i play my game at 720p, then scale it in obs to 480p. is there a smarter way to do this? should I just output 720 or do something else?

also

i have tried streaming at 5000 kbps for hours without any drops/issues
should I increase/decrease my kbps based on my speeds?

x264 encoer settings and preset dont effect QuickSync.
You will have to see for yourself if increasing the output resolution will effect pixelation, that really depends on the game and available bandwith. 4000 bitrate is pretty high already, you could give 720p@60FPS a try with 4000bitrate and see if you like that quality over the 480p.

In general there is less quality loss when you don't need to downscale a resolution e.g. streaming at 720p while playing at 720p at the same time.
