A level has two known defects: a rare collision gap that lets players fall out of the world (occurs in 1% of playthroughs) and a common visual glitch where a wall texture flickers (occurs in 80% of playthroughs). The team has limited time to fix only one before release. Which defect should be prioritized and why?

Fix both by allocating extra resources, even if it delays release.

Fix the collision gap because it causes a hard progression block and potential soft-lock, despite its low frequency.

Fix neither because both are minor and can be patched later.

Fix the texture flicker because it affects most players and is more noticeable.

A level uses red and green color-coded buttons, but a color-blind player cannot distinguish them. Which type of defect is this?

Accessibility and usability defect

Which of the following defects should be given the highest priority for fixing?

A broken objective that prevents level completion

A minor visual glitch that appears briefly

A missing landmark that causes some confusion

A texture seam that is barely noticeable

A level has a large vista with many distant objects that cause a high number of draw calls, leading to frame rate drops. The team wants to maintain the visual quality of the vista while improving performance. What is the most effective solution?

Reduce the resolution of all distant textures.

Replace distant objects with 2D billboards or sprites.

Increase the camera far clip plane to show more objects.

Use level-of-detail (LOD) meshes and occlusion culling to reduce the number of rendered objects at distance.

During a playtest, testers notice that a wall texture has visible seams where two texture tiles meet, and the lighting appears inconsistent across the seam. What is the most appropriate action?

Adjust the UV mapping and ensure the texture is tileable without visible seams.

Change the wall material to a solid color.

Add more geometry to the wall to hide the seam.

Increase the texture resolution to make the seam less noticeable.
