我不确定我是否可以正确执行3d渲染？下面是我的3d渲染方法的一种方法。当我在桌面上运行游戏时，它可以60fps正常运行，但是当我在android上运行时，它只能以15fps运行。当我注释掉这种方法时，我也会得到60fps，所以我认为问题出在我的3d渲染代码中。
你能告诉我是否正确吗？
private void draw3d() {
gameViewport.apply();
modelBatch.begin(gameCamera);
modelBatch.render(highwayInstance, environment);
modelBatch.render(highway2Instance, environment);
modelBatch.render(highwayLines, environment);
modelBatch.render(buttons, environment);
if (activeMetronomeFirsts.size != 0) {
int activeMetronomeFirstLength = activeMetronomeFirsts.size;
for (int i = activeMetronomeFirstLength; --i >= 0;) {
modelBatch.render(activeMetronomeFirsts.get(i).getMetronomeInstance(), environment);
}
}
if (activeMetronomes.size != 0) {
int activeMetronomeLength = activeMetronomes.size;
for (int i = activeMetronomeLength; --i >= 0;) {
modelBatch.render(activeMetronomes.get(i).getMetronomeInstance(),environment);
}
}
if (activeSnares.size != 0) {
int activeSnareLength = activeSnares.size;
for (int i = activeSnareLength; --i >= 0;) {
modelBatch.render(activeSnares.get(i).getSnareInstance(),environment);
//activeSnares.get(i).draw(modelBatch);
}
}

int activeTom1Length = activeTom1s.size;
for (int i = activeTom1Length; --i >= 0;) {
modelBatch.render(activeTom1s.get(i).getTom1Instance(), environment);
}
}

int activeRideLength = activeRides.size;
for (int i = activeRideLength; --i >= 0;) {

for (int i = activeTom2Length; --i >= 0;) {
