Massive performance hit on Realms since the 1.19.30 update. Low fps, laggy performance, erratic chunk loading.

My primary system is a Razer Blade 15 with NVidia RTX2060. 16GB RAM, and Intel Core i7-9750H @ 2.60 GHz. Usually I get a locked 60 fps on Realms. Currently experiencing between 12 and 30 fps. Chunks are also loading erratically, particularly immediately after spawning in to the server. There is also greatly increased "lag" with stuttering animations, stop-start movement, and generally a lack of smooth performance.
