你的游戏客户端有mod吗？正常情况下崩溃是因为mod过多或使用内存超过电脑所能承受的范围而崩，
当然也有些特例，比如你没加mod或者mod很少，没有超出电脑范围，
那样的话也许是电脑的问题或者是客户端的问题，建议换个电脑/客户端试一试
如果以上两种都不是，就加一个mod吧，高清修复，不会很卡，比原版好一点，
不过我觉得应该是mod或内存闹的，就看你说“玩游戏时是不是会出现透视”可能是电脑卡了，因为mod过多
希望我的回答对你有帮助！

那就让你的基友把他的forge发给你，不知道怎么弄的可以回复我

你跟他联机，对方不愿意用forge跟你没关系吧。。你自己用就好啦

加个高清修复

崩溃应该因为内存不够了吧 我多开经常爆这个 主要看楼主电脑配置 分配1000m太低了  如果楼主是64位机器 可以尝试多分配一点 如果是32位的 配置一般的话 只能考虑装forge装优化mod 至于联机 如果是局域网联机你装forge联机应该是不影响的（至少你链接他没有问题）如果是服务器联机 那就不存在影响

或者你可以试试换个JAVA?

把游戏内存调高

实话说出来吧，基友的电脑配置很好，但是他是来我家里玩，共用局域网联机，出问题的是我的手提电脑，台式机一点毛病没有，但我的手提电脑是64位，而且总体配置比台式机还好，还是出毛病，换forge后，一个mod没有，主机客机都会卡，所以不想换forge
