Hey man how did you get everything to look like that on HPG? In the first video you posted. The colors are sort of brighter than mine, and the textures seem to 'pop' more. It looks really good, and everything is clearly visible.
OBS is a free program that does very good recordings, has a great UI, and is used by most streamers. It may eat a little on your performance tho. https://obsproject.com/ Love the battlemusic what's the artist?
I just keep a bunch of music on my desktop for whenever I play this game. I have a dropbox if you want to dig. Just pm me if your interested.
