Java LWJGL游戏
我正在学习LWJGL，我正在写一个简单的游戏。但是如果我渲染200x200级别，我有10-15 fps。我添加了一个renderLimiter，使用它，我有40-60 fps的Vsync。如何加快渲染速度？下面是一个代码（不是100%）： 游戏。类别：Java LWJGL游戏,java,lwjgl,Java,Lwjgl,我正在学习LWJGL，我正在写一个简单的游戏。但是如果我渲染200x200级别，我有10-15 fps。我添加了一个renderLimiter，使用它，我有40-60 fps的Vsync。如何加快渲染速度？下面是一个代码（不是100%）： 游戏。类别： package main; import static org.lwjgl.opengl.GL11.*; import java.applet.Applet; import java.awt.Canvas; import org.lwjgl

如果你想要更多的代码，告诉我。对不起我的英语：（。你能做的就是使用不同的渲染技术，渲染器类中的许多方法都使用所谓的即时模式渲染。尝试学习如何使用顶点缓冲区对象（VBO）或显示列表。它们速度快得多，并且会大幅提高游戏的平均FPS:）基本上，通过使用VBO的。用谷歌搜索它，然后按照教程进行操作。它们在渲染方面提供了极大的性能改进。
