DLSS 5 Mod Shifts Load to Second GPU, Doubling Frame-Rates and Latency
Digital Foundry • • general
Key Points:
- DLSS 5 introduces a rendering time cost of approximately 8-12ms, which typically results in frame rates being halved and a corresponding increase in latency compared to normal DLSS.
- Under Nvidia's intended conditions, this performance cost appears to be a fixed overhead applied to the final rendered frame, limiting potential improvements from developer optimization, although Nvidia has indicated possible future speed-ups up to 7 times faster.
- The main bottleneck for DLSS 5 performance likely involves both memory bandwidth and compute resources, but there may be opportunities to adjust settings to regain performance headroom.
- In practical testing across 25 games at 4K with maxed graphics settings, DLSS 5 generally maintains playable frame rates near 60 fps, with noticeable performance gains as long as the upscaling threshold stays below 75–80%.
- DLSS 5 is regarded as a significant technological advancement in graphics quality and performance, described as a revolutionary leap comparable to the shift from 2D to 3D gaming.
