Question 3

What does the Unreal Engine 'Stat GPU' console command provide during QA testing?

Accepted Answer

Per-pass GPU timing breakdowns on screen

Answer

'Stat GPU' overlays GPU timing data for individual render passes, helping QA identify which passes are causing GPU bottlenecks.

When using Unreal Engine's Level Streaming, what QA test should you perform to verify memory usage stays within budget?

Accepted Answer

Profile memory with 'Stat Memory' before and after streaming levels in and out

Answer

Using 'Stat Memory' before and after streaming level transitions confirms that loaded levels fit within the memory budget and that unloaded levels are properly released.
