RTSS asynchronous limiter vs in-engine limiters
Unlike in-game frame limiters that frequently suffer from 1-2 ms pacing jitter, RTSS regulates frame presentation at the driver level, creating a razor-flat frametime graph.
Scanline Sync for Fixed Refresh PanelsOn monitors without VRR/G-Sync, Scanline Sync places the tearline off-screen, offering tear-free gameplay without V-Sync input lag.
Telemetry diagnostic graph configuration
Setting up an active frametime graph exposes whether performance hiccups originate from CPU draw calls, GPU ceilings, or asset streaming.
Key Takeaways
- •RTSS delivers the flattest frametime line with zero pacing jitter.
- •Scanline Sync removes screen tearing without traditional V-Sync lag.
- •Visual frametime charts immediately expose hardware bottlenecks.
