Nvidia Just Made Path Tracing Better and Easier to Run | PCMag
Maybe it'll make those retooled RTX 3060s that bit better.
www.pcmag.comNvidia’s latest path tracing news is that its researchers have an updated ReSTIR PT approach that they say can make full path tracing about 2x to 3x faster, while also improving image quality and reducing noise. Reports published on April 20–21, 2026 describe speedups in the roughly 2.08x to 3.05x range, with an average improvement around 2.74x in some scenes.[9][10]
What changed
The improvement is tied to an enhanced version of ReSTIR PT, Nvidia’s real-time sampling method for path tracing. The new approach is described as reducing correlation artifacts, color noise, and disocclusion noise, which means it can look cleaner while needing less denoising.[4][9]
What it means
This is research news rather than a shipping consumer feature, so it does not mean every game will suddenly run 3x faster today. But it does suggest that path tracing may become much more practical for future games and could help bring the visual style to more GPUs.[10][4]
Best source summary
The strongest reporting so far says Nvidia’s enhanced ReSTIR PT can reach 2.08x–3.05x speedups and improve visual quality at the same time. PCMag’s summary also notes that the algorithm may render path-traced lighting up to 3x faster while reducing errors and denoising needs.[4][9]
