What to look forward to: Adding ray tracing to classic games was a great way to showcase the difference it has. Last week, the modder posted a trailer on YouTube showing the original Half-Life’s feature. The modder plans to make it playable this year, although no specific date has been given.
Sultim_t says in his trailer for Half-Life: Ray Traced that he will add real-time path tracing to Valve’s original 1998 first-person shooter. Ray tracing effects include global illumination, reflections, refractions, and soft shadows.
Path tracing is similar to ray tracing, but much more complex and computationally intensive. Ray tracing in games like Cyberpunk 2077 or Resident Evil Village mixes with traditional rasterization, processing only effects such as global illumination or reflections. In comparison, path tracing renders the entire scene using ray tracing.
It takes so much power that only games with relatively simple or outdated graphics, such as Minecraft or Quake II RTX, can run it at playable frame rates. However, even these games require scaling techniques such as DLSS. Sultim_t doesn’t mention any scaling feature for Half-Life: Ray Traced.
Sulim_t earlier developed a ray tracing mod for Serious Sam, although this mod based on a previous attempt to add ray tracing to Half-Life. Sulim_t plans release See it on GitHub along with the source code when you’re done. In 2019, Nvidia said it plans to bring ray tracing to more classic games, but hasn’t announced anything since.
