您好,您先在桌面打开该图层,在场景属性勾选“帧率信息”查看场景中帧率,如果小于25帧的话,就得检查图层并对图层进行优化,如“移除重复点”“移除重复面”等操作,可参考博客https://blog.csdn.net/supermapsupport/article/details/89473986?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522162035496916780265452642%2522%252C%2522scm%2522%253A%252220140713.130102334.pc%255Fblog.%2522%257D&request_id=162035496916780265452642&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~blog~first_rank_v2~rank_v29-7-89473986.nonecase&utm_term=%E4%BC%98%E5%8C%96。数据优化之后如果还是卡顿,得看一下您的网络是否流畅以及电脑配置是否有独立显卡。
