273The renderer provides comprehensive performance analysis:
274 
275```rust
276let report = renderer.get_performance_report().unwrap();
277 
278// Frame timing analysis
279println!("Average frame time: {:.2}ms", report.frame_stats.average_frame_time * 1000.0);
280println!("Frame time variance: {:.2}ms", report.frame_stats.variance * 1000.0);
281 
282// Memory analysis
283println!("Peak memory usage: {}MB", report.memory_stats.peak_usage / (1024 * 1024));
284println!("Current allocations: {}", report.memory_stats.active_allocations);
285 
286// GPU analysis
287println!("GPU utilization: {:.1}%", report.gpu_stats.utilization * 100.0);
288println!("Memory bandwidth: {:.1}GB/s", report.gpu_stats.memory_bandwidth);
289```
290 
291### Bottleneck Detection
292 
293Automatic detection of performance bottlenecks:
294 
295```rust
296for bottleneck in &report.bottlenecks {
297 match bottleneck.category {
298 BottleneckCategory::Memory => {
299 println!("Memory bottleneck: {}", bottleneck.description);
300 println!("Suggestion: {}", bottleneck.suggestion);
301 }
302 BottleneckCategory::GPU => {
303 println!("GPU bottleneck: {}", bottleneck.description);
304 }
305 BottleneckCategory::CPU => {
306 println!("CPU bottleneck: {}", bottleneck.description);
307 }
308 }
309}
