About CrystalMark 3D25

CrystalMark 3D25 is a 3D benchmarking software that allows you to easily measure 3D performance (GLSL/WebGL) with a single click.
It was developed with the goal of showcasing the appeal of the demo scene to PC enthusiasts (benchmarkers) worldwide, featuring works provided by demo scene creators who support Japan’s demo scene.

This project would not have been possible without SESSIONS. We extend our heartfelt gratitude to FL1NE, the SESSIONS staff, and everyone supporting the demo scene.
We look forward to your participation in SESSIONS 2025! (CrystalMark Inc. is a sponsor.)

How to use

Benchmark

Click the “All” button to run the Scene1-4 benchmarks in order.
Clicking the “Scene1,” “Scene2”, “Scene3” and “Scene4” buttons will run the benchmarks individually.

Submission to CrystalMarkDB

Click “Submit” button to go to the registration page to CrystalMarkDB via web browser.
Click “QR” button to display QR code for data registration to CrystalMarkDB. Please read it with the camera of your smartphone or tablet.

In a retro environment, QR code generation may take several minutes or more.

Post to X (Twitter)

Clicking on the “X” button will take you to a screen for posting to X via a web browser. Please attach screenshot of CrystalMark Retro manually.

GPU Selection

Mmultiple GPUs may be displayed. You can choose one from several GPUs. However, you do not have the ability to choose which GPU to use for benchmarks.

System Requirements

OS	Windows 11
Architecture	x64

• This is compatible with Windows 11 and later, so it does not support x86.
• It does not support ARM64 because it does not support OpenGL by default.
• Scene 4 may crash during testing on older, slower GPU environments. Lowering the resolution to 1280×720 or similar may allow it to complete.

Score

Scores are calculated based on the number of pixels rendered per second.
Scenes 1-3 may see improved scores by disabling vertical sync (V-sync).
Scene 4 uses WebView2, which forces vertical sync to be enabled.
Therefore, Scene 4’s score may vary slightly depending on the display’s refresh rate.

Release note

I had always longed for 3D benchmark software, and now I’ve finally made it a reality.
