If you want to have fun with real-time ray-tracing in games – a feature that is exclusive only on RTX 20-series cards thus far – then this is good news for you. The brand new NVIDIA driver update with version number 425.31 enables real-time ray-tracing for most GTX cards. We have talked about real-time ray-tracing here previously.

This new driver version enables some existing Pascal cards and also the GTX 1660 and GTX 1660 Ti to run real-time ray-tracing as well. This list of graphic cards does not have dedicated RT cores, hence its ray-tracing capability is limited. Whichever the case may be, these cards can do some real-time ray-tracing after this driver update:

ASUS ZenBook 13 UX333
  • Pascal architecture
    • GeForce GTX 1060 6GB
    • GeForce GTX 1070
    • GeForce GTX 1070 Ti
    • GeForce GTX 1080
    • GeForce GTX 1080 Ti
    • NVIDIA TITAN X (2016)
    • NVIDIA TITAN Xp (2017)
  • Turing architecture
    • GeForce GTX 1660
    • GeForce GTX 1660 Ti
    • GeForce GTX 1660 Ti
    • Existing RTX 20-series GPUs (obviously)

Laptops which are running the mobile version (or Max-Q) counterparts of these GPUs are also capable of whipping out some real-time ray-traced lights after installing the latest update.

NVIDIA also highlighted that there are 4 different types of workloads for ray-tracing – ambient occlusion, shadows, reflections, and global illumination. These different workloads put a different amount of load on your GPU, hence some ray-tracing techniques are much more lightweight compared to the others.

To further understand these types of reflections, here are some animations.

To put things in perspective, NVIDIA has mentioned that these GPUs are mostly only going to be capable of real-time ray-tracing with playable frame rates at 1080p resolution. The lower-tiered GPUs might need to tune down from ultra settings too.

NVIDIA also provided some benchmarks of their own to compare and contrast the performance difference in the presence of dedicated RT cores. With ray-tracing enabled, even the RTX 2060 can outperform the GTX 1080 Ti. Do take note that these benchmarks are running at 1440p.
