The sizes have different sizes (customizable). Sometimes there's taking random screenshots from Xsplit, sometimes it's taking screenshots from games on the PC (but I usually play windowed so the borders are in the way). There's a few instances of me taking screenshots of the Virtual PC too or certain sections of what I browse on the browser (*cough* kongregrate).
My laptop is Windows 8 (which sucks lol) and there's my Windows 7 which is the main computer. I don't think there's Python on them.
Since the Laptop is 1920x1080 instead of 4K,
I'll show a random screenshot of Rocksmith score on "learn a song". (Click me)
Some stuff was edited so you can't stalk me.
Unrelated, but if you ask - the VM Windows XP is there to play old classic games like Warcraft 3 and stream them without the "movie cutscenes" forcing a black screen, change the ratio or anything to ruin the viewer experience. Know any tricks to play windowed on Windows 7 without that shit happening?
