Part 2 — Answer key

Compare your answers after you have finished Part 1.

1. In a typical 3D console game, which control is most often used to look around or move the camera view?
   Right stick
2. Increasing the resolution in a video game usually makes the image look sharper but can lower performance on weaker hardware.
   True
3. You are installing a new general knowledge quiz video game on a console that supports different storage options. Which storage choice will typically give you the fastest level loading times?
   Internal solid-state drive
4. A player finds the screen in a trivia-style gaming quiz cluttered and hard to read. Which UI option is most likely to improve clarity without losing important information?
   Enable simplified HUD mode
5. In an online video game, your ping value measures how quickly your graphics card can draw each frame on the screen.
   False
6. Colorblind or accessibility modes in modern video games commonly adjust color palettes and contrast to help players distinguish important elements.
   True
7. A designer of a fast-paced video game quiz adds a cooldown timer after using a powerful hint ability. What is the main gameplay reason for this mechanic?
   To prevent players from using the hint repeatedly
8. In a console-based general knowledge quiz video game, a player uses an analog stick to move a cursor over answer options but keeps overshooting the choice. Which change is most likely to improve their control?
   Lower the analog stick sensitivity
9. You want to optimize a 3D gaming quiz for mid-range PCs. Which graphics settings mainly increase GPU load rather than CPU load? Select all that apply.
   Screen resolution; Texture filtering; Shadow quality
10. A player of an online video game trivia quiz experiences random lag spikes on Wi-Fi while other devices in the home are streaming video. Which single change is most likely to stabilize their connection?
    Use a wired Ethernet connection
11. If a game is limited by CPU performance, lowering the resolution will always result in a much higher frame rate.
    False
12. A general knowledge quiz video game tracks how quickly players answer correctly and secretly adjusts question difficulty so that success stays around 70%. What design technique is this an example of?
    Dynamic difficulty adjustment
13. A team is creating a new level for a video game quiz. Arrange these tasks in the typical order they should complete them to build a polished level.
    Correct order: High-level concept sketch → Blockout or graybox layout → Playtesting and iteration → Art polish and audio pass
14. A competitive video game quiz shows scores, a countdown, bonus multipliers, and chat all at once. Players report that they often miss how much time is left. Which interface tweak would most directly fix this issue?
    Increase the size and contrast of the timer
15. A player of an online gaming quiz wants to reduce input delay and lag during matches. Which actions are most effective? Select all that apply.
    Choose servers located closer to their region; Close bandwidth-heavy downloads on the network; Use a wired Ethernet connection instead of Wi-Fi
16. On a PC running a 3D video game quiz, frame rate hovers between 45 and 55 fps and the goal is a stable 60 fps with minimal visual loss. Which single change is most likely to help reach that target?
    Lower shadow quality from ultra to medium
17. A small studio is building PCs to develop a 3D video game quiz in a modern engine. Which components most strongly affect build times and in-editor responsiveness? Select all that apply.
    GPU model; Amount of RAM; CPU performance
18. Analytics for a free-to-play mobile quiz show many new players quit after the first session because rewards feel too spaced out. Which design change best addresses early-player retention without breaking long-term balance?
    Increase early-level rewards and then taper them later
19. A competitive shooter-style trivia game runs at 144 fps on clients, but players report inaccurate hit registration even with low ping and no visible stutter. Server diagnostics show a relatively low server tick rate. Which change would most directly improve how accurately the server detects hits?
    Increase the server tick rate
20. An advanced user tweaks a 3D game engine for a visually rich video game quiz lobby scene. Which rendering features typically have a significant impact on GPU performance? Select all that apply.
    Detailed post-processing effects; High sample count for dynamic shadows; Screen-space ambient occlusion
21. On a PC running a 3D general knowledge quiz lobby, a hardware overlay shows GPU usage around 50%, while one CPU core is near 95% and storage activity spikes whenever new assets stream in. The game stutters during these spikes. What is the most likely performance bottleneck?
    CPU or storage limitation
