Key points - Blur Busters founder Mark Rejhon says people over 40 remember CRT motion clarity, while younger people have never seen it. - Nvidia's G-Sync Pulsar uses backlight strobing and rolling refresh to create perceived 1,000 Hz clarity, but only on Nvidia GPUs. - In late 2024, Rejhon and Timothy Lottes debuted an algorithm that simulates CRT phosphor fade on 240+ Hz displays. - The Asus ROG PG27AQWP-W is a 540 Hz OLED monitor with a 720 Hz mode at 720p, ideal for CRT simulation. - ShaderBeam, a standalone tool, requires perfect synchronization with display and input to avoid noticeable flashing.
Timeline - Mid-2000s: LCDs replace CRTs, offering thinner screens but worse motion clarity with ghosting. - Late 2024: Mark Rejhon and Timothy Lottes debut a breakthrough CRT simulation algorithm for 240+ Hz displays. - 2026: Nvidia's G-Sync Pulsar launches in gaming monitors, but not on OLEDs and only for Nvidia GPUs. - 2026: ShaderBeam tool splits from ShaderGlass to handle complex CRT beam simulation on Windows.
FAQ
Q: What is CRT simulation and why does it matter? A: It's a technique that mimics the motion clarity of old CRT monitors on modern displays, reducing blur for smoother gameplay. It matters because many gamers miss that CRT smoothness.
Q: Can I use CRT simulation on any monitor? A: No, you need a high refresh rate display, ideally 240 Hz or more. OLEDs are best because they can go completely black and get very bright, closer to CRT contrast.
Q: Why does Windows need to change for true CRT nirvana? A: Windows isn't built for the perfect synchronization required by CRT beam simulation. Dropping a single frame causes noticeable flashing, so the OS needs better timing support.
