大家好，我希望有人可以帮助我解决这个问题。我无法让硬件加速在配备英特尔集成显卡的笔记本电脑上工作。
问题：
在使用带有 JFrame 的 BufferStrategy 的 Windows 7 和 8 机器上，使用 Java 7 更新 11 的硬件加速似乎无法与英特尔集成显卡一起使用。
细节
显卡：Intel(R) HD Graphics 4000
JRE：Java 7 Update 11
操作系统：Windows 7、Windows 8

如果您想验证问题，您可以下载我为测试创建的应用程序：http: //ndcubed.com/downloads/GraphicsTest.zip
如果您不喜欢下载已编译的 JAR 文件，您可以使用自己编译应用程序以下源代码：
package graphicstest;
import javax.swing.*;
import java.awt.*;
import java.awt.image.BufferStrategy;
public class GraphicsTest extends JFrame {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new GraphicsTest();
}
});
}
GraphicsConfiguration gc = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDefaultConfiguration();
BufferCapabilities bufferCapabilities;
BufferStrategy bufferStrategy;
int y = 0;
int delta = 1;
public GraphicsTest() {
setTitle("Hardware Acceleration Test");
setSize(500, 300);
setLocationRelativeTo(null);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
setVisible(true);
createBufferStrategy(2);
bufferStrategy = getBufferStrategy();
bufferCapabilities = gc.getBufferCapabilities();
new AnimationThread().start();
}
class AnimationThread extends Thread {
@Override
public void run() {
while(true) {
Graphics2D g2 = null;
try {
g2 = (Graphics2D) bufferStrategy.getDrawGraphics();
draw(g2);
} finally {
if(g2 != null) g2.dispose();
}
bufferStrategy.show();
try {
Thread.sleep(16);
} catch(Exception err) {
err.printStackTrace();
}
}
}
}
public void draw(Graphics2D g2) {
if(!bufferCapabilities.isPageFlipping() || bufferCapabilities.isFullScreenRequired()) {
g2.setColor(Color.black);
g2.fillRect(0, 0, getWidth(), getHeight());
g2.setColor(Color.red);
g2.drawString("Hardware Acceleration is not supported...", 100, 100);
g2.setColor(Color.white);
g2.drawString("Page Flipping: " + (bufferCapabilities.isPageFlipping() ? "Available" : "Not Supported"), 100, 130);
g2.drawString("Full Screen Required: " + (bufferCapabilities.isFullScreenRequired() ? "Required" : "Not Required"), 100, 160);
g2.drawString("Multiple Buffer Capable: " + (bufferCapabilities.isMultiBufferAvailable() ? "Yes" : "No"), 100, 190);
} else {
g2.setColor(Color.black);
g2.fillRect(0, 0, getWidth(), getHeight());
g2.setColor(Color.white);
g2.drawString("Hardware Acceleration is Working...", 100, 100);
g2.drawString("Page Flipping: " + (bufferCapabilities.isPageFlipping() ? "Available" : "Not Supported"), 100, 130);
g2.drawString("Full Screen Required: " + (bufferCapabilities.isFullScreenRequired() ? "Required" : "Not Required"), 100, 160);
g2.drawString("Multiple Buffer Capable: " + (bufferCapabilities.isMultiBufferAvailable() ? "Yes" : "No"), 100, 190);
}
y += delta;
if((y + 50) > getHeight() || y < 0) {
delta *= -1;
}
g2.setColor(Color.blue);
g2.fillRect(getWidth()-50, y, 50, 50);
}
}
结论
在没有硬件加速的情况下，我创建的许多应用程序需要它在具有集成显卡的机器上运行缓慢。我真的很困惑为什么它不能专门使用这种类型的显卡。无论如何，感谢您阅读所有这些内容，希望我们能够深入了解 :)！
