About
Don't Knock Twice is a first-person horror game from 2017 that puts players inside a grand manor house filled with environmental puzzles and supernatural dread. Based on a creepy urban legend about a vengeful witch, the game focuses on exploration and interaction rather than combat, letting you uncover a dark story by examining nearly every object in your surroundings. It's a solid indie horror title that blends psychological tension with adventure-style exploration.
The game is quite accessible from a performance standpoint, making it a good benchmark title for testing entry-level GPUs. You'll need at least 4 GB of RAM and a GPU with a minimum score around 1174 to run it, which means even older or budget graphics cards can deliver smooth FPS at standard settings. Most modern systems will easily handle Don't Knock Twice at high quality, making it useful for performance testing across various GPU tiers without demanding cutting-edge hardware.
With a 63/100 rating, Don't Knock Twice offers a decent experience for horror fans who appreciate slower-paced, story-driven games over action-heavy scares. If you enjoy exploring atmospheric environments and don't mind a middling critical reception, it's worth trying, especially since it won't strain your hardware.
Performance profile
August 2017 release. Don't Knock Twice was built around the GTX 10-series / RX Vega era. Current-gen mid-range cards (RTX 4060 / RX 7600) are overkill at 1080p and handle 1440p Ultra comfortably.
Don't Knock Twice is a narrative-driven experience — a rock-solid 60 FPS is plenty. Prioritise resolution and image quality (AA, anisotropic filtering) over chasing high-refresh framerates.
Extremely light — Don't Knock Twice runs at 60 FPS 1080p on any integrated GPU (Intel Iris Xe, AMD Radeon Graphics) or a decade-old discrete card like the GTX 1050. A current-gen RTX 4060 pushes 4K Ultra without effort.
