A very impressive Grand Theft Auto V PC graphics mod is currently doing the rounds in video form, and it's actually a great example of what we may come to expect from the PS5's ray tracing tech.
For those out of the loop, ray tracing is a feature that Sony is already emphasising whenever it's talking about the PS5. Without getting too technical, ray tracing is a method of simulating more realistic lighting effects in computer graphics. In other words, it allows for light to coat surfaces and fill space in a much more realistic way, often resulting in visuals that are closer to photorealism, both at first glance and on closer inspection.
Again, the video that we've embedded above is a fantastic example. There are both outdoor shots and indoor shots that show off ray tracing to excellent effect, and this is the same kind of tech that developers will be harnessing on the PS5.
The mod itself stems from the work of Pascal Gilcher, a specialist in creating graphics mods and shaders. One of Gilcher's Patreon supporters applied Gilcher's still-in-development ray tracing mod to the PC version of Grand Theft Auto V, and here we are.
Anyway, if you've never been quite sure what ray tracing is all about, hopefully you're a little more up to speed now. You can probably expect to see similar tech demos, specifically for next-gen consoles, over the coming months as we get closer and closer to the PS5's release (which is supposedly happening next year). If you haven't already seen it, EA recently released its own footage of some next-gen hair. Interesting stuff.

They just have to add ray tracing and GTAV will be ready for release on a 3rd generation of console.
@Rhaoulos Top of the charts for another decade guaranteed
Its not just lighting that Ray Tracing impacts but also things like Reflections too. Of course it depends on the complexity of the scene and GPU load as to whether Ray Tracing is used for everything, how many rays are actually projected etc and/or used in conjunction with more traditional gaming techniques.
I think its testament to game developers in the past that have created incredible - almost lifelike lighting, shadows etc - good enough that people haven't exactly been disappointed - but seeing Ray Tracing scenes compared, you realise how much is actually 'wrong' with the traditional methods.
Looking good, Los Santos.
60 fps and quick loading time are enough to make me buy gta5 ps5 remaster, add raytracing and maybe 4k then it’s day one buy
"ray tracing is a method of simulating more realistic lighting"
Does that mean "Spiderman: Webmastered" on PS5 can get it's puddles back? 😅
Didn't think much about ray tracing till I saw it in action. Having it on console will speed up adoption.
Unreal and Cryteck already implementing it at the engine level. PS5 is shaping up nicely. Already started putting momey aside for it 😀
Looks great in GTA 5 in the video. Another copy of that game for me to purchase. GTA 5 for PS5, remastered with ray tracing. Hopefully at 60fps and with dof and motion blur options.
This ray tracing bullfish is exactly what could hamper the 4k60fps almost everyone is hoping for. I don't know the gpu in the ps5 but seeing how the rtx2080ti suffers serious frame drops with ray tracing, I am not excited about it all. I don't understand these gaming companies sometimes, they always find a bottleneck or something to hamper performance. I hope they give options to turn it off to improve performance. Ray tracing my backside. DieKaiser92.. Ouut!!!
@NintendoFan4Lyf I haven't done a lot of research on those games in particular. BF5 for example has multiple settings for the Quality of its Ray Tracing - the usual low, medium, high etc. It maybe that Reflections are the most obvious implementation and why its highlighted to show its impact. Metro too may well be using Ray Tracing for more than just Global Illumination but that's the area that is impacted the most. I think I remember seeing something about Metro's reflections in water (or maybe think I did).
Ray Tracing could be used for multiple visual improvements and used to 'enhance' certain aspects on top of the more traditional rasterisation. By that, I mean that a game could use Ray Tracing for Global illumination primarily and as a 'secondary' use to add some more dynamic reflections or Shadows - especially on 'higher' settings.
With AI, Ray Tracing could give much higher results with much lower rays - AI being used to fill in the gaps left by using fewer rays. AI is being used by TV's now to improve upscaling. The more it learns as to what the missing pixels should be, the better the upscale will look. I believe nVidia GPU's have something similar - DLSS (deep learning super-sampling) and AI could 'learn' to accurately predict the way rays interact on the scene rather than have to send a lot more Rays and plot their path.
Its early days yet and I hope its not just a 'buzz-word', something that Sony are saying because its a hot topic. I hope its a meaningful use rather than a 'token' effort.
Impressed with Ray’s tracing
As awesome as this is, I can’t help but feel sad; generational leaps now seem to amount to nothing more than the same games you had, only prettier.
It says a lot about the incredible advances made in the last twenty years, but now it seems that this incredible raw power will go towards making games prettier, instead of making them more mechanically advanced and offer us new ways to play.
Well, let’s wait and see, I hope I’ll be proven wrong
@NintendoFan4Lyf What I meant by 'Buzz word' was in relation to the PS5 (or next Xbox) where its a 'tick box' to say that their console can do Ray Tracing because its phrase that's synonymous with high end hardware.
I hope that its more than just superficial, more than just an option but with a big cost - like saying a console can do 4k but the cost of that higher resolution means a big drop in Frame rate. I hope that Ray Tracing isn't something that comes with a 'big' cost to either resolution or Frame Rates or more than just a 'token' effort if the game doesn't drop resolution or frame rates.
At the moment, Ray Tracing is an expensive process - as we see in BF5. A GTX 2080ti can't run that game at 4k/60 with a 'high' Ray Tracing setting. What I hope is that with the PS5, we are not given the choice of 4k/60 with standard rasterization or drop to 1080p only (or 1440p if you drop to 30fps) if you want Ray Tracing. With current mid gen consoles, some games give you the choice of high resolution or high frame rate and I hope that Ray Tracing isn't an either/or choice, a choice to use it but have to compromise on resolution and/or frame rates if you do opt to use it.
It does bug me as a 4k TV owner that I have too sacrifice resolution to have 'higher' frame rates. I didn't buy my Pro (or X) to play games in HD just to get better performance and I don't really want to have sacrifice resolution or frame rates to have ray tracing.
I have no doubt that Ray Tracing will continue to advance, that it is a valuable tool to developers etc. I can see the PC market improving no end with GPU development improving and expanding what devs can achieve with Ray Tracing in games. I don't really want consoles to hold them back either and maybe DLSS (or some AMD version) and other 'tricks' (like Chequerboard Rendering) can be utilised to achieve a decent '4k' (not native but incredibly close visually) image with a decent Ray Tracing implementation.
As I tried to imply, AI could also come to the next gen consoles aid and make the 'sacrifice' of resolution to deliver a 'high' standard ray tracing image without compromising on frame rates much more achievable from relatively inexpensive hardware. AI could be used to upscale and predict the effect of many more 'rays' than are actually being traced. Cut down on the workload so it can deliver an image that looks incredibly similar to a native 4k with a comparably high quality implementation of Ray Tracing.
This is what I meant by 'buzz word' - something that the console can do but it lacks the necessary power to implement it without some big costs elsewhere, something people may decide isn't worth 'turning on' because the drop in other areas is not worth it.
Ray tracing looks wonderful and all but i mostly care about 60fps MINIMUM!
1st on the list, make games play ultra smooth. First its companies stupidly pushing resolution, now this. If you can do it without any negative effects then sure awesome but the core base of games should be priority imo
GTAV is on sale at the moment and I almost thought twice about buying it. But now it’s almost my mission in life to never play it.
Is the reason why everything in this video is stationary because if there was something moving, it would be 10 frames per second and set their 6 grand rig on fire?! We don't know what's in a PS5 yet but we do know this would make it melt
The comparison video does a great job making the difference obvious. Impressive, not so much. I have no reason to doubt that on the tech side it's an objectively impressive achievement as far as photorealistic visuals go; I just fail to feel wowed by it myself.
