All You Need to Know about Pimax

PPD (pixels per degree) measures how many display pixels span each angular degree of a user's view in a VR headset. A higher PPD means finer detail and less visible pixelation (screen-door effect). In VR, boosting resolution alone isn't enough — you also need to pack more pixels into each visual degree to match the eye's resolving power. Thus, PPD is more meaningful than raw resolution for perceived clarity. High PPD helps with reading small fonts, seeing distant objects sharply, and improving immersion, especially in simulation or VR productivity use cases. Pimax offers different optical engine options for the Crystal Super, including 50 PPD and 57 PPD. Both versions use the same internal resolution (3840 × 3840 per eye) and refresh rates.

FOV (field of view) is one of the most important specs of a high-end VR headset. FOV defines the visible area that a VR user can see while wearing the headset. A wider FOV not only enhances the feeling of presence within virtual space but also reduces motion sickness.

Pimax's thoughtful design maximizes the FOV for individual users without compromising pixel density or introducing distortion. While accurately measuring and describing FOV can be challenging, testing and user feedback confirm that the Pimax Crystal Light offers a wider FOV than other popular headsets on the market. Its unique expanded vertical FOV provides flight simulation players with a broader view of the cockpit and the sky, delivering a more natural, immersive experience that closely matches the human eye's peripheral vision.

is the portion of a headset's field of view that both eyes see at once. This overlap is critical for depth perception, as it allows the brain to combine images into a true 3D view. While a wide FOV enhances peripheral awareness, insufficient overlap can reduce stereoscopic realism and comfort.

The Crystal Super Ultrawide, a variant of the 50 PPD QLED engine, maintains the same panels, lenses, and edge-to-edge clarity but expands FOV to 140°. By reducing overlap from 105° to 90°, it caters to users who prioritize FOV—particularly sim racing enthusiasts.

Local dimming is a technology used in displays, such as televisions and computer monitors, that allows for more precise control over the brightness levels of different areas of the screen, resulting in a clearer, more vibrant, and more immersive picture. It can help to improve the quality of the image by reducing blooming and increasing contrast.

Crystal Light features a QLED display, which offers superior color accuracy, higher brightness, and better energy efficiency compared to traditional LCD screens. QLED with local dimming solves the issue of limited contrast in darker areas, delivering the perfect blacks needed for night flights in MSFS or dark scenes in Metro. However, if you don't mind low contrast in darker areas, the non-local dimming version will be available in the future.

Crystal Super advances the local dimming technique even further with 1,000 dimming zones per eye, each controlled by an independent driver. This allows precise handling of highlights and shadows, creating OLED-like contrast while maintaining QLED brightness.

Pimax Play is Pimax's comprehensive software platform designed to enhance the VR experience. It offers a range of features, including customizable settings for optimal performance, easy access to VR content, and seamless integration with Pimax headsets. With regular software updates, Pimax Play continuously improves, providing users with advanced options to enhance visuals and tools for fine-tuning their VR setup. It's designed to ensure that Pimax users get the most immersive and fluid experiences possible while making VR more accessible and enjoyable.

DFR (Dynamic Foveated Rendering) and FFR (Fixed Foveated Rendering) are techniques used in VR to improve performance by reducing the rendering workload. DFR dynamically adjusts the image quality based on the user's gaze, focusing high-detail rendering on the central area of the view. In contrast, FFR applies a fixed reduction in image quality to the peripheral areas, regardless of the user's gaze.

Eye tracking plays a key role in DFR by enabling the system to know exactly where the user is focusing, allowing for more accurate and dynamic rendering adjustments. Crystal Super is designed from the ground up to maximize the benefits of eye tracking. The 10 IR LEDs per eye and 120 FPS tracking facilitate clean, low-latency eye data.

While Pimax Crystal Light dismisses the eyetracking unit to reduce its price and weight. It still provides significant performance improvements through FFR, which reduces the rendering quality on the periphery of the view, ensuring smooth and immersive gameplay.

Quadview (or Quad-Views Foveated) is a technique that splits rendering into four regions: two high-resolution "focus" zones and two lower-resolution peripheral zones. Unlike Fixed Foveated Rendering (FFR), where fixed rings of lower resolution follow the view, or Dynamic Foveated Rendering (DFR), where the high-res zone tracks your gaze via eye tracking, Quadview can more aggressively reduce resolution outside the focus areas, boosting performance. It's especially useful in graphically demanding sims like DCS, where it's already supported and can produce large FPS gains.

With the recent Pimax Play update, advanced users now have direct control over Quad Views rendering parameters when running in OpenXR mode. This powerful feature allows you to manually fine-tune the rendering pipeline to better align with your GPU's capabilities, thermal headroom, and visual fidelity targets.

You can adjust the following parameters:

These settings empower users to make conscious trade-offs between GPU load and image sharpness, especially valuable in VR simulation titles where performance margins are tight.

Even the most powerful GPUs can struggle in ultra-demanding VR titles. GPU Upscaling in Pimax Play solves this by rendering frames at a slightly lower internal resolution—say 70–80% of native—and then intelligently upscaling them back to full resolution for display.

You can choose between two highly optimized methods:

• AMD FSR 1.0 – Works seamlessly on both Radeon and GeForce GPUs, delivering sharp visuals with minimal overhead.

• NVIDIA NIS – A lightweight, driver-level upscaler now fully integrated into Pimax Play for VR.

Both techniques are designed to retain fine details and smooth edges, so the final image looks nearly indistinguishable from native—especially during motion. The benefits are clear:

• Higher Framerates: Smooth performance even in the heaviest scenarios like MSFS, DCS, and modded Skyrim VR.

• Lower GPU Load: Reduced power consumption, heat, and noise from your system.

• Extra Headroom: Use the freed performance to increase refresh rate, install complex mods, or push settings higher.

• Minimal Visual Compromise: Smart filters and sharpening keep textures crisp and aliasing under control.

This makes GPU Upscaling an ideal solution for users with mid-to-high tier graphics cards (e.g., RTX 3080, RX 7800 XT) who want to maximize smoothness without giving up clarity.

For moments when your GPU can’t quite keep up, Smart Smoothing steps in to maintain fluid motion. By intelligently generating synthetic frames, it keeps the refresh rate steady and reduces visible stutter, even during heavy scenes like dense airports in MSFS or intense dogfights in DCS. This helps your brain stay “in the world,” minimizing discomfort and motion sickness.

For those who love to tweak, Pimax Play also offers custom render resolution control, allowing you to set exactly how many pixels your GPU should render. This means you can dial in the perfect balance between image sharpness and GPU load—whether you want the absolute clearest visuals for screenshots or smoother performance for competitive play.

Upscale Mode is an innovative feature that employs advanced upscaling algorithms to improve frame rates in VR games. It is designed to optimize performance without requiring an upgrade to your GPU. By enhancing the effective resolution of your visuals, it delivers a smoother and more fluid gameplay experience. Unlike basic resolution adjustments, this mode intelligently increases detail and sharpness, offering a significant performance boost.

At Pimax, we are constantly pushing the boundaries of VR technology to provide our users with the most immersive and fluid experiences, whether through optimizing existing products or developing future innovations.
