16 FPS @ 4K on a $1600 4090. LMAO. Guys, guys, the 2060 6GB is totally "wray traycing ready", yo! Reminds me of hardware PhysX when they told us blowing cloth @ 15 FPS was the "game-changing future".
Ray Tracing is a solution looking for a problem. We already had very good approximated water reflections, water ripples, mirrors and lighting that ran fast on basic hardware. Heck, mirrors were around in Duke Nukem 3D software rendering back in 1996.
Also "just flip a switch and everything automatically works without developer effort" is an absolute lie. In reality assets/surfaces/textures need to be specifically designed for bouncing rays or they won't look right.
The classic example is when they bolt RT onto old games and have to add a flashlight and a fake sun in the middle of the sky because three quarters of the game is pitch black now.
And now that we have RT, it has created a new problem: too slow. So the "solution"? TV upscaling and frame interpolation, branded as "aye eye features". All vendor-locked to nVidia, of course.
