Question / Help Recording Seems shuttering With No Reason


New Member
Hi to everyone this is my first post!
I would like to know why my recording seems shuttering/having graphic glitches.
I was recording Modded Minecraft (Like 180 Mods).
I have only an idea, could it be a RAM problem caused by the high usage of Modded Minecraft?

My Pc Specs:
I7-4770 3.2 GHZ
8 GB RAM DDR3 1600 MHZ
RX 550 4GB

P.S.: I couldn't find the log file

I'm attaching an example:
