Question / Help Pixelation when turning in game

So I've recently started streaming Guild Wars 2 to Twitch and everything seems fine with quality except when I turn the camera in game. It pixels out and gets blurry. When I'm just standing or not turning the camera it looks perfect. My hardware can handle the strain and still have enuf power to handle a few other streams if I wanted I think the biggest issue is with my upload rate from my isp.
I was told when I first started the account with my isp that I could get uploads of 7mbps which is a lie. So they gave me a new modem and switched my lines for 1 pair to 2 pair and the most they could get me is 1.45 mbps upload which is laughable. I set my bitrate to 1100 to keep from getting dropped frames. If it was at 1200 i get about 15% dropped frames. All the setting are pretty much default for the 0.625b versions of OBS. except that I changed the fps to 50. So how can I solve the pixelation issue?
On another note, when using the 64 bit version all i get on stream is a black screen. It only seems to work with the 32 bit version even tho I have a 64 bit system.

Best way to use x264 as encoder, then lower your quality and set your encoder to a slower speed from veryfast to maybe faster/fast. Also, lower your resolution helps.

Without enough upload, you can't simply do magic to get it good.

this log isnt helpful at all..

but since you said you run everything on default i assume you try to stream 1080p and you said you changed to 50 fps... which is quite useless and needs way too much bitrate to look decent when moving.

downscale to 720p use 30 fps

see how much changes and make sure to post a useful log of an actual streaming session

The default was downscaling to 720p and I changed the fps to 30 but i still get some pixelization. Also those are the only logs that I have. I've looked at all of the logs and they look identical to that one. So unless they are being saved elsewhere other than the default that OBS puts them idk.
**Edit
Here is the last streaming log I found.

that log is the right one :)

well your cpu isnt the best anymore so you have not really much headroom to play around with presets that much

i would suggest trying something like 480p25fps on fast preset and see how your cpu handles it but i can already tell that theres no posibility for you to make an mmo look good while moving with that bitrate to actually be happy about it you will always have quite some quality dips :(

Well I streamed at 720p at 30fps yesterday and almost all pixelisation was gone. But later on it had some. It seemed to come and go so I am thinking part of the issue is Twitch itself.
On another note. The CPU I have is a very good cpu even if it is a few years old. It can handle GW2, microsoft word, browser and other things at the same time and still only be using about 40% cpu. and i don't even have it overclocked. Im not pro intel like some people in this forum so idc. AMD has always worked great for me

It has nothing to do with Twitch. A 720p30 stream at 1100 Kbps is going to be pixellated whenever there's a lot of motion in the scene because the bitrate you're using is too low to maintain good quality. You'll want to allocate about twice that amount of bandwidth, assuming it's available, to make things look decent more consistently.

While I'm sure your CPU is fine for playing most games, that does not mean it's always going to be fine for playing most games and streaming at HD resolutions at the same time. Real time video encoding is a lot of additional work and can easily be more demanding than a game.
