      Many people that play on Windows 10 used to install the x86 build of Minecraft Bedrock because it has no render dragon (Until 1.18.30 existed). The main reason many used to play on this version is because of the blatant performance issues, and input delay for literally any version with render dragon in it. This doesn’t happen anymore because of nearly every server changing their support to the more recent versions. The game just simply feels significantly laggier, especially on most servers. I have a pretty good pc, but I have an extremely noticeably weaker performance on any version with render dragon. In the attachment (bugreport33.mp4), I test and compare the performances of 1.16.100 (A version without render dragon), 1.16.200 (the first render dragon release), and 1.17.30 (the latest release as of the publishing of this report). Each version will be tested on the same server with the same map, a single-player infinite world, and a world with absolutely nothing in it, all with the exact same video settings. The FPS averages will be at the end of the video. 

      Update (made during 1.20.30): Render dragon for a while has been improved on RTX cards, and now the different DirectX engines can be toggled thankfully. An issue on many servers (and probably any medium resource-intensive scenario) is that I’ve been able to feel very small micro lag performance spikes many times a second. Once again, this did not happen when I used the older rendering engine. Lastly, entities seem to be the culprit of many performance issues as well.
