These are you VIDEO SETTINGS. Bicubic o Lanczos filter give bettter image quality.
In this log, the section about graphics cards is not present. In previous log:

So, you have a Radeon R9 200 and also the integrated graphics. OBS runs on your radeon card
Video settings rescale is always done by your GPU.
NOTE: last log says
00:44:48.058: Warning: The OpenGL renderer is currently in use. On windows, the OpenGL renderer can decrease capture performance due to the lack of specific features used to maximize capture performance. The Direct3D 11 renderer is recommended instead.
CHANGE in Adcanced Settings to Direct3D 11 for better performance.

THIS IS OUTPUT SETTINGS SECTION
You are using ONLY 300KBPs bitrate . TOO LOW. 1280x720x30fps needs minimum 1800 Kbps. You can use 2500 for better quality.
(1280x720x60fps minimum is 2500 kbps)
Buffer size = bitrate (1800 , 2500, what you use)
Rescale in VIDEO SETTINGS and leave OUTPUT SETTINGS rescale unchecked.
In my experince, this causes double rescaling --> stream lag even with smooth ingame experience

Self explained section.
Rendering lag only 0,5%
So, try changing
VIDEO SETTINGS: rescale filter bicubic (if no lag, try with lanczos)
OUTPUT SETTINGS
Bitrate 1800 minimum, 2500 recomended for better image (30fps)
2500 minimum for 60 fps (1280x720p)
NOTE: FOR 1080p in VIDEO SETTINGS Mdo not rescale and set filter to bilinear and 30 fps. In Output setting, leave rescaling unchecked and bitrate 3500 for 1920x1080x30fps - if not partnered with Twitch, do not rise to 4500 for 60 fps)
I hope this makes it easier for you to check your log by yourself.
EDIT:
This is for better stream quality.
About ping ingame, provide a new log when you get good image on stream and then we will have more info.
