const device = director.root?.device;
if (device) {
info += `DC: ${device.numDrawCalls}\n`;
info += `Tri: ${device.numTris}\n`;
info += `Tex: ${(device.memoryStatus.textureSize / 1024 / 1024).toFixed(2)} / ${(device.memoryStatus.bufferSize / 1024 / 1024).toFixed(2)}\n`;
}
if (profiler.isShowingStats()) {
profiler.stats && (info += `FPS: ${profiler.stats.fps.counter.value.toFixed(2)}\n`);
}
this.labInfo.string = info;
