Quake II running with NVIDIA's RTX tech.

NVIDIA promised us a world of difference with RTX, but applications so far have fluctuated between disappointing to moderately impressive improvements to visual quality. So I think it’s only fair that NVIDIA took the time out at their recent GTC 2019 conference to showcase just how powerful a properly implemented RTX implementation can be. With Quake II RTX, NVIDIA breathed new life into a game, that after 22 years, might convince you to buy another new graphics card!
