FAQ:
A full FAQ can be found on my website (above). Here’s a short list:

● How many FPS do you get?
Because frames differ because of entity count (tile and living), here are a few (smooth lighting on, render distance on far):
Hypixel Lobby: 200 FPS
WoodyCraft Lobby: 180 – 200 FPS

● What programs do you use?
Total Media Extreme to record my HDPVR, OBS to record my PC, Sony Vegas to edit, Audacity to capture audio, and Call Graph to record skype.

● What livestream software do you use?
OBS free-ware.

● Where did you get your computer from?
From CyberPowerPC.com. I’ve had no problems with my pc. I recommended some friends there, and they had no problems.

● What content do you provide?
Primarily showcases on minecraft mods and plugins as well as Bukkit development tutorials.

● What is your Minecraft Texture pack/ how is it HD?
I usually use either Faithful 32x or Sphax 128x.

I have 64 gb on my server and its ecc (error correcting memory) and in console it has been showing in lan mangment that ram chips are overloaded but it only has 20 players online wich means mincraft server is very badly optimised

Heres a little bit of a faster way, turn render distance to 10, should get better. His video is also very useful 🙂 earned a sub tho
