Only a disingenuous person could call RT a gimmick. Raster effects (such as SSR, cube maps, cascaded shadow maps, pre-baked lightmaps and GI) mimic what RT does, and therefore can be considered a gimmick. Ray tracing technology is the exact opposite of a gimmick, and that's why it's so expensive.
As of now there are over 100 games with RT support, while this hardware unboxed comparison only shows limited number of games from that list.
I agree about the dead space remake, RT is unnoticeable in this game, and I'm sure there are couple more games like that. However, in the vast majority of games I have played, RT has made at least a noticeable difference, and a generational difference when it was fully utilised.
RE Village looks definitely better with ray tracing. Water reflections no longer fade out as you move the camera and look sharper, and RT GI sometimes makes a big difference too (especially in darker areas lit only with indirect lighting) as shown in digital foundry comparison video. These are welcome improvements considering how well this game runs, I get 130-160fps in 4K native on my PC.
In RE4 remake RT was a little bit downgraded compared to the RE Village and even RE3 remake (RT reflections in the RE3R were pretty much everywhere), however RT water (on the lake) in RE4R still looks a lot better compared to raster while only tanking 1fps on my PC, so it was absolutely worth to use it.
Callisto Protocol, that game has much better shadows quality thanks to RT, and very noticeable RT reflections. I saw this difference almost everywhere without looking for it, so it was quite noticeable I would say.
RT reflections in callisto protocol have reduced resolution, but it's better to have reflections with reduced quality than no reflections at all.
RT in shadow of the tomb raider doesnt make huge difference in all locations, but the difference is still there and I wouldnt want to play this game without RT. I hate cascaded shadow maps, and RT also increases the number of rendered shadows. In some locations (especially in the caves) that difference was huge.
Hardware Unboxed labelled RT in Mero Exodus (Standard Edition) as different image, but unclear if better
. Good joke. The lighting without RT looks flat in this game and character models dont even match the scene. It seems Hardware Unboxed experts are blind, and you are blind as well by blindly repeating their false opinions.
I even prefer original Metro Exodus compared to the EE, because developers have destroyed atmosphere and the look of the game. Enhanced Edition has raised blacks and blown out highlights.
As for the witcher 3 next gen, this game should be in the category "transforms visuals significantly". The lighting without RT looks flat, cascaded shadows maps draws literally in front of Geralt, and screen space reflections fede out as you move around the water.
Black Myth Wukong use RT regardless of the settings ("lumen" is software RT) but with PT the lighting looks a lot better even at medium PT settings while only tanking 3% performance on my PC.
RT requires more hardware resources, but it's also very scalable. On my PC RT performance hit is usually around 20-30%, and up to 70% with PT but DLSS + FG can improve performance by a factor of 5x times, so personally I dont even care about RT performance impact. I always turn RT on. This would not be the case if I had bought the RX7900XTX. Even with medium PT games like Black Myth Wukong wouldnt run at 120fps. What's more the RX7900XTX doesnt even support RR, so I would get way more noise in games like Alan Wake 2. So yes, I can understand why AMD fans such yourself arnt happy about RT performance, but RTX 40 series (and soon RTX 50) offers very good RT performance.
31 fps on the RTX3080ti, and 81 fps on the RTX4090. You tried to say that the RX7900XTX dont have much worse RT performance compared to ADA Lovelace GPUs, but this AMD card cant even match the RTX3080ti in this game. The gap in RT performance is absolutely huge, and only the new RDNA4 9700XT could change that (will see).
