not only that, but the new and entirely unnecessary bumpmaps applied to certain areas like Hydlaa, the Stonehead, guildhouses, Amdemnier and Oja (basically anywhere not wilderness) are enough to send most systems into a tantrum spiral which can result in perceived lag, client freezing, system freezing, client crashing, complete system shutdown, or even user spontaneous combustion in worst cases.
Work arounds include lowering your graphics settings, if you don't mind playing in a gloomy, dimly lit world (shaders on low) or an oversaturated cartoon land (shaders on lowest). Either of those combined with the patented 'Look Straight Down' camera angle should result in an almost bearable gameplay.
