not only frame drops but input lag. What you need is a good enough GPU and figure out whether vsync should be on or off for you, then set a framerate limit. Play with it and it will end up running a hell of a lot better. Bedrock running poorly because of render dragon isn't always because of the hardware being too bad
As a top minecraft bedrock speedrunner I can say that there is a faster set seed, its called the ice boat seed, the current world record on that seed 2:16 held by OphieSR.
lol I only just stumbled across this one. I'm guessing they got the seed from someone elses video else they would have known to go for the sheers -> cobwebs -> string -> wool -> beds strat.
