Nvidia printed a brand new YouTube video this morning exhibiting Cyberpunk 2077’s new RT Overdrive mode in motion with a GeForce RTX 4090. The graphics are unimaginable, however so is the efficiency hit on the RTX 4090. The totally path-traced renderer introduced the RTX 4090 to a snail’s tempo and ran the sport at simply 16 FPS natively with the mode energetic. To attain favorable body charges, DLSS 3’s body technology and upscaling have been required. However let’s take a second to step again and dissect exactly what we’re speaking about right here.
RT Overdrive mode is a brand-new rendering mode being added to Cyberpunk 2077 on April eleventh. (opens in new tab) The brand new graphics mode replaces the sport’s present ray-tracing pipeline with a completely unified path-tracing resolution that considerably expands the sport’s rendering engine. There isn’t any hybrid rendering, solely ray traced pixels. Nvidia has beforehand demonstrated this mode, and it notes that on common it wants 635 ray calculations per pixel — in comparison with simply 39 rays per pixel with Battlefield V, one of many authentic launch video games for RTX ray tracing.

The common ray tracing modes in Cyberpunk 2077 have been a hybrid rendering resolution, consisting of rasterization together with ray-traced reflections, international illumination, and different results. With the totally path-traced resolution, each single mild supply within the sport is simulated to generate essentially the most real looking lighting, shadows, and reflections potential.
All mild sources within the sport are path-traced, along with Nvidia applied sciences together with NVIDIA Actual-Time Denoisers (NRD) (opens in new tab), NVIDIA RTX Direct Illumination (opens in new tab) (RTXDI), and Shader Execution Reordering (SER) (opens in new tab) to enhance picture high quality and speed up efficiency. It is mainly the identical overhaul that Nvidia did with Portal RTX, solely now utilized to a considerably extra trendy and demanding sport engine.

Overdrive is the brand new Crysis
Nvidia’s YouTube video demonstrates the absurd efficiency penalty of working a AAA title like Cyberpunk 2077 with full-blown path tracing enabled. Nvidia used a GeForce RTX 4090 to run the Overdrive tech demo at 4K decision, and the GPU could not even hit 30FPS at native decision.
To attain playable body charges, Nvidia used DLSS 3 body technology together with picture upscaling (DLSS 2 Efficiency mode) to get body charges again into the triple digits. That is just like Portal RTX — one other totally path-traced sport, the place the RTX 4090 additionally wanted DLSS 3 body technology and/or upscaling to realize playable body charges.
This could put into perspective how rather more demanding 3D mild simulation is in comparison with simply faking it. However fortunately, we’re now on the level the place good high quality mild simulation might be executed in real-time, even when it nonetheless typically wants upscaling to get to first rate body charges.
We do not know the system necessities but for this new Overdrive mode, however its protected to say you will most likely want a top-tier RTX 30-series GPU, or one in all Nvidia’s RTX 40-series GPUs, to run Overdrive mode at excessive body charges. Contemplating Nvidia was working at 4K, you’ll be able to most likely get first rate efficiency at 1080p with far much less potent GPUs than the RTX 4090, and Cyberpunk 2077 does help each DLSS 2 and AMD FSR 2.1 upscaling.
We’ll must see what efficiency seems to be like on different GPUs when the free replace arrives on April 11.
