The sad reality is, the hype behind RT is simply insane.
I have seen only a couple of times (Quake and Minecraft) were RT seemed to make a nice difference. The rest seems to be same thing "lets pause the game and concentrate in this beautiful ray-traced puddle".
The performance hit taken by what I feel is very little gain its simply not worth it.
Better yet, the ones that have fallen for the hype also ignore the fact that the amount of games that have it AND produce any reasonable results are very few.
Yeah, people act like Ray-Tracing is some incredible thing. This is especially true with the younger set who don't know what a real graphics game-changer is. So today, I'm going to compare Ray-Tracing with a REAL game-changer (graphics-wise) that came out around ten years ago.
So, to be fair to Ray-Tracing, I'll use the most dramatic and successful implementation in gaming thus far, Control:
The first picture does have the most dramatic difference I've ever seen and it does look REALLY good. Having said that, the game still looks REALLY good with it off. It's not like the first picture is ugly and, as stated, this picture is the most dramatic differential picture that I could find. I won't say that the second picture doesn't look better because of course it does but, as with all of these ray-tracing pictures, the only way to notice is to have them side-by-side because the difference is all environmental eye-candy.
This one shows a nice reflection on the floor. Would I notice this during gaming? Absolutely not. Again, the only way it's noticeable is if we're looking at it like this. Otherwise, it would have no effect whatsoever.
In this pic, she looks redder but what I find really funny is that the purely rasterised pic on the right has a reflection that's about 95% as good as the one on the left. Ray-Tracing makes literally no difference here.
Speaking of a "Who Cares?" kind of pic, I showed this to a couple of co-workers and asked if they could see any difference between them. The most common answer? "I can see an extra button in the right-side pic." Not one person noticed the darker shadow at her hairline.
- Need I say more?
This one really makes me laugh because I actually think that she looks better
without Ray-Tracing enabled.
Hardware Canucks actually had to put arrows to show the differences between these pictures. What does that tell you?
And I think that this one is from Cyberpunk 2020:
Yep, that extra green reflection on the ground is a real game-changer alright. It looks like Slimer from Ghostbusters had a bit of a diaper accident there so don't step in it!
Now, all jokes aside, let's look at a REAL game-changer in gaming graphics, perhaps the biggest game-changer in gaming graphics since the invention of rasterisation. It was first widely seen in the Unigine Heaven benchmark from about ten years ago and is called...TESSELLATION.
Tessellation was a REAL game changer because it had a dramatic effect on the detail and geometry of EVERYTHING. A game with tessellation only barely resembled a game without it because the difference was literally night and day:
I'm certain that I don't have to explain just how much more epic Tessellation is compared to Ray-Tracing. Even more close-up, you can see the dramatic difference between them:
Back then, tessellation was also pretty hard on the fps rates. Of course, nVidia was up to their usual shenanigans as well by putting absurd levels of tessellation into their GameWorks developer packages. They were right that Tessellation was an amazing innovation but they pushed it for a different reason. That reason was that their cards were set up for it but ATi's cards weren't. ATi's cards certainly could do Tessellation but they took a larger performance hit than nVidia's did. However, nVidia's GameWorks was so overblown with Tessellation that it actually hurt the experiences of GeForce users. The reason that nVidia did this was because it hurt Radeon users even more. Yes, they were a bunch of Richards even back then.
Now you know what a REAL game-changing graphical innovation is and what it can do. Ray-Tracing is, and will probably always be, nothing more than a fancy frill. Don't get me wrong, the idea of Ray-Tracing is a good idea, but it has been horribly over-hyped by nVidia and I don't think that it will ever have the same revolutionary effect on gaming graphics as Tessellation did and still does today.
