According to PC Gamer and Digital Foundry, the 2080Ti can drive Metro Exodus with RTX on at average 55fps with drops down to 30fps at 4K resolution so your claim seems grossly exaggerated - https://cdn.mos.cms.futurecdn.net/YhDHpgGrAmpmnP4LUBEgvg.png

Also last I read, RTX really isn't designed for offline raytracing and doesn't really bring much to the table. Its use is in realtime.

Battlefield V Ultra 1080p RTX on is ~63 FPS average (not minimum FPS, but average), which means it will regularly dip below 60 in practice.

On the contrary! RTX Cores are a hardware-accelerated BVH-traversal. That has HUGE implications for the offline rendering scene.

See NVidia Optix for details: https://devblogs.nvidia.com/nvidia-optix-ray-tracing-powered...

IMO, this is the killer-feature of RTX. Accelerating those Hollywood Renders from hours-per-frame to minutes-per-frame. NVidia Optix takes industry-standard scene trees and can use the RTX Cores to traverse them for hardware-accelerated raytracing.

Or more specifically: coarse AABB Bounds checking, which is a very compute & memory heavy portion of the Raytracing algorithm.

Even if RTX is too slow for video games, any improvement to offline rendering is a huge advantage.

Optix was developed a decade ago and doesn’t require RTX cards. It run on any Maxwell or newer card. It’s NVIDIA’s version of RadeonRays.

What NVIDIA is trying to sell people is a denoiser.

And are you sure RT Cores even exist or are they just tensorcores by a different name?

In the RTX announcement speech, they repeatedly mentioned the savings for offline rendering (taking fewer computers less time and fewer watts to render the same quality). I came away from watching that thinking that the card was primarily positioned for offline rendering.
