Install a bare linear switch into a rigid plate. Do not install a keycap. Press the switch until actuation (2.0mm). Record the force graph. This is your "zero" benchmark.
Most reviewers use a switch tester. They press a bare stem. This is a mistake. A naked switch feels nothing like a switch dressed with a GMK Double-shot ABS or a PBT SA keycap.
The superposition benchmark key top test corrects three critical failures of standard keyboard reviews: superposition benchmark key top
If you want to verify your score against the data above, follow this strict protocol. Running it incorrectly leads to "invalid" results that waste your time.
Step 1: Download Unigine Superposition (Standalone) Do not use browser-based versions. Download the 1.1GB installer. Install a bare linear switch into a rigid plate
Step 2: Select Custom Preset
Step 3: Configure Shader Complexity Set Shaders to Ultra. Set Volumetric Lights to High. Note: Setting "Tessellation" to "Dynamic" reduces the load by 30%—do not use this for benchmarking. Step 3: Configure Shader Complexity Set Shaders to Ultra
Step 4: The "10-Minute Loop"
The standard benchmark runs for 90 seconds. For stability testing, use the command line argument:
superposition.exe -scene key_top -loop 10 -log_interval 1
This runs the Key Top scene for 10 minutes continuously, logging FPS every second.
Step 5: Interpret the Logs
