Thanks for the link. Their ray tracing analysis gives a good explanation on why some scenes appeared much darker when RTX was enabled.

Gamegpu used the wrong driver Nvidia GeForce 418.81 instead of 418.91.

Sure, Techpowerup used 417.22....

Perhaps they weren't testing DLSS like gamegpu claims to be.

Perhaps it's a conspiracy against Nvidia? /s
Guru3D with 418.91
DLSS OFF + DXR High roughly same results as GameGPU

What I find interesting is Nvidia recommended TechPowerup to use driver 417.22 for their ray tracing analysis, which might indicate a there might be a bug discovered in subsequent drivers. We'll see how this plays out.

RTX on vs off in Metro, the difference is jaw dropping IMO, particularly in outdoor scenes

GameGPU and Guru3d tested the internal benchmark, which isn't representative of the gameplay in the game across most levels.
TPU tested without DLSS, they did a separate article for it.
Well, after watching the scenes a few times, it pains me to say this, I would say that RTX is not a must-have yet. It's still mostly gimmicky.
There are some (not all!) scenes outdoor scenes, where the difference between RTX on and off is huge, but I wonder if RTX-on-like quality could not have been achieved with conventional means, maybe with lower quality. And I'm a little underwhelmed by the little difference in the indoor scenes. I always thought that flashlights would be the case where RTX shines.
We still have RTX support for Shadow of the Tomb Raider coming up. Let's see how that will work out. Apart from that, do we have any other games with RTX support to look out for?
Opinions I guess, but when even the makers of this video have a hard time telling which is which (“wait is this RTX on or off?” at around 8 minutes in) then I know that I’m not being difficult here.
Problem is that if this wasn’t a side by side comparison, I (and many others) wouldn’t be able to tell the difference.
Heck, I can’t even tell the difference half the time in the side by side comparison! It mostly comes down to being a little brighter or a little darker here and there.
Sorry, this is not the RTX killer app that it’s being made up to be.
Yeah. Compared to the Minecraft illumination that was a real game-changer, Metro's RTX is making very little difference. BFV's reflections have a more significant impact on visuals.
Lack of bounce from local lights makes it quite bit less visible in many locations, difference in those places come from improved AO or AO length.
If it's no must have yet, they why would you think this would ever change?
Games developed from the ground up to use RTX (DXR) would benefit more from its lighting. eg. We hear that RT has to be turned off for stealth portions of a game because it screws with the dark lighting. The game was developed without RT in mind and its incorporation wasn't great. So just like VR needed to get some 'killer apps' like Astrobot to justify it, RTX is still waiting. (Of course, by the time great RT showcase games come out, RTX will be outdated and underpowered. 
).
).Because I think in the future we will get the the point where games uses things like physically correct refractions, translucency, reflections, real-time GI and you instantly can tell the difference between DXR/RTX on and off.

That's the nature of ultra settings in general, the differences between High and Ultra in most games is hard to spot without side by side comparisons, heck, even the difference between High, Medium and low is hard to spot most of the time.

The problem with games is that while lighting should behave correctly, the lighting setup itself can't usually be exactly the same way it is in reality. It's the same as in movies. Lights still have to be placed where in reality they wouldn't be, or you'd simply not get the visibility that is required to enjoy the content.
So DXR will not 'just work', because the artist will still need to place some lights without which you just wouldn't be able to play properly - example: very dark scenes with one candle in the room. Sorry but one candle does not cut it, in movies or games or anything. There is always extra lighting here and there, and if you think about it that's still 'cheating'.
