1. Frame Rate Fundamentals

   Which setting adjustment is most likely to increase a game's frame rate without noticeably lowering visual quality for most users?

   1. Lowering resolution from 1080p to 720p
   2. Reducing shadow quality from ultra to high
   3. Turning off vertical synchronization (V-Sync)
   4. Decreasing monitor refresh rate

   Explanation: Reducing shadow quality from ultra to high can significantly improve frame rate, as shadows require intensive computation, but the decrease in visual fidelity is often barely noticeable. Lowering resolution drastically affects image sharpness and is easily observed by users. Disabling vertical synchronization may lead to screen tearing rather than true frame rate gain, while decreasing the monitor refresh rate does not increase the GPU's frame processing ability. Therefore, adjusting shadow settings is the best compromise for better performance with minimal visual loss.

2. GPU Thermal Stress Testing

   During a GPU stress test, what is the main reason for monitoring the graphics card's temperature?

   1. To improve audio output
   2. To boost internet connection speed
   3. To adjust display brightness
   4. To prevent thermal throttling or hardware damage

   Explanation: Monitoring GPU temperature during stress testing is critical to avoid thermal throttling, where the hardware slows down to prevent overheating, or in extreme cases, to prevent permanent damage. Audio output is unrelated to GPU temperature monitoring. Network speed and display brightness are not influenced by the GPU’s operating temperature during stress tests. Thus, the primary concern is maintaining GPU health and stability.

3. Bottleneck Identification

   If a gaming system shows high CPU usage and low GPU usage with low frame rates, what is the most likely cause?

   1. The monitor refresh rate is too low
   2. The graphics drivers are up to date
   3. The CPU is bottlenecking the system
   4. The GPU is overheating

   Explanation: High CPU usage with low GPU usage and poor frame rates usually indicate a CPU bottleneck, meaning the processor cannot keep up with rendering demands so the GPU is underutilized. GPU overheating can reduce performance, but would typically show high usage before throttling. Monitor refresh rate affects perceived smoothness but not raw frame calculation. Updated graphics drivers usually enhance rather than hinder system performance, making CPU bottleneck the best answer.

4. Synthetic vs. Real-World Stress Tests

   Which statement best describes a key difference between synthetic GPU stress tests and real-world gaming benchmarks?

   1. Synthetic tests produce consistent, repeatable maximum loads
   2. Real-world benchmarks are less accurate than synthetic tests
   3. Synthetic tests reduce the need for cooling solutions
   4. Synthetic tests use imaginary hardware components

   Explanation: Synthetic tests are designed to create controlled, repeatable maximum loads on the GPU, making it easier to compare performance across systems or configurations. They do not use imaginary hardware but simulate heavy workloads. Real-world benchmarks can vary more depending on game or application updates, making them less repeatable but more representative of typical usage. Cooling solutions are equally important in both cases, as neither type reduces hardware heat output.

5. V-Sync and Frame Rate Behavior

   What typically happens when vertical synchronization (V-Sync) is enabled during a GPU stress test and the GPU cannot maintain the monitor's refresh rate?

   1. Frame tearing increases noticeably
   2. The system heats up at a slower rate
   3. The frame rate drops to a divisor of the monitor's refresh rate, like 30 FPS on a 60 Hz screen
   4. The frame rate exceeds the monitor’s maximum refresh rate

   Explanation: With V-Sync on, if the GPU can't match the monitor's refresh rate (such as 60 Hz), the output frame rate usually drops to the next lower divisor, like 30 FPS, to keep synchronization smooth. Frame tearing typically decreases rather than increases, which is the purpose of V-Sync. The frame rate will not exceed the monitor’s refresh rate when V-Sync is active. There is no direct effect on system heating rate due to V-Sync settings—the GPU workload remains primarily driven by rendering demands.
