I would say that your channel is not user friendly for SEA or low internet connection. Mostly people tends to look for gameplay of a game rather than graphics. What your channel provides are quite odd, aiming for the top most section of gamers in general.

But then again, most of people normally don't look for that kind of thing. I could say that your channel is quite unique for what it is doing, and might be becomes the top in their section. However, for a gaming channel in general, there is hardly any interesting.

This has a poor comments work, slow, uninteresting script and you sounds too nervous. If it is about technical slideshow, we want to have something informative, interesting information in general.

TLDR; You need to work on your speaking script.
