Ray Tracing & Tech Support

What is Ray Tracing?

Ray tracing is a rendering technique that acts like a digital camera, simulating how light actually bounces, reflects, refracts, or diffuses around a virtual scene. While regular rasterization fakes a lot with shortcuts and tricks, ray tracing actually follows each light ray to see what it hits. If a ray smacks into a shiny floor, you get a reflection. If it passes through glass, you see it bend and scatter—just like in real life. The result? Deep, immersive visuals: real reflections in puddles and windows, natural soft shadows, and lighting that makes rooms look truly lit up instead of just "brightened" with effects.

Ray tracing has quietly powered movies and CGI behind the scenes for decades, but it wasn't until 2018—when dedicated RT hardware showed up in consumer graphics cards—that real-time ray tracing in games became possible. Now, hundreds of games use some sort of ray tracing, and every new GPU generation brings it further. The tech keeps getting better, and the results are more lifelike with each jump.

How Our Ray Tracing Checker Works

Our Ray Tracing Checker gives you a clear look at what your GPU can actually do with ray tracing. Once you enter your graphics card model, the tool matches it against our detailed GPU database. It checks which ray tracing cores your card has, what generation it's from, whether features like DLSS, FSR, or Frame Generation are supported, and gives you an idea of your card's overall ray tracing performance. Instead of just saying "yes, ray tracing is supported," it breaks things down—does your GPU handle basic reflections only, or is it ready for full path tracing? It also lets you know which upscaling technologies you can use to keep performance playable, because honestly, upscaling like DLSS or FSR isn't optional with ray tracing—it's a requirement for smooth frame rates. Our tool's performance rating reflects real-world benchmarks, so you know how your card will hold up in different games and at different settings.

Ray Tracing Performance Impact

Turning on ray tracing taxes your GPU, sometimes a lot. How much your frame rate drops depends on the RT effects you use, how the game implements those features, and how powerful the dedicated RT hardware on your card is. You can usually expect a hit of 30-50% to your FPS compared to traditional graphics, but results vary. In some games, basic ray traced reflections might only cost you 20-30%. Crank things up with multiple RT effects or go for full path tracing, and you might get only half the original performance—or less.

NVIDIA cards with dedicated RT cores handle ray tracing much better than AMD cards in the same performance class. NVIDIA put a ton of work into its ray tracing hardware starting with the RTX 20 series, and each generation since—RTX 30, RTX 40, and now RTX 50—pushes RT performance even further. The RTX 40 doubled the number of rays handled compared to the previous series, and RTX 50 improved things even more. AMD's RDNA 2 and 3 cards do have ray accelerators, but they just can't catch up to NVIDIA's per-ray speeds, and so they lose more performance with RT enabled. AMD's latest RDNA 4 cards have reduced the gap a bit, though. No matter which team you're on, though, you need upscaling like DLSS or FSR for smooth framerates if you want ray tracing switched on. For example, with DLSS Quality mode turned on, an RTX 4070 can handle most ray traced games at 1440p with no trouble. Turn off the upscaling, and even the best GPUs sometimes struggle to keep 60 FPS.

Types of Ray Tracing Effects

Not all RT effects are equal in looks or in performance cost. Most games offer a mix of these options, so it's good to know what you're turning on. Ray Traced Reflections are the most common—think of perfect reflections in water or glass that show things even if they aren't on your screen. These usually cost a moderate 15-25% performance but look great. Ray Traced Shadows give you soft, realistic shadows with a natural penumbra, instead of blocky edges. They typically drop FPS by 10-20%, so it's one of the best RT features to enable first if you want an upgrade in visuals without tanking your performance.

Ray Traced Global Illumination (RTGI) is where things get intense. It simulates the way light bounces around the room or a scene, making everything look much more natural and immersive. It also hits your frame rate, costing 25-40% or even more. Ray Traced Ambient Occlusion adds deeper shadows in the cracks and corners—so it's more subtle, but adds realism without slowing your FPS too badly. On the extreme end is Path Tracing. This one renders the entire scene with rays, ditching any shortcuts. It's used in a handful of games like Cyberpunk 2077's Overdrive Mode and Alan Wake 2 for truly stunning visuals. You'll need at least an RTX 4080 (with DLSS) to get playable frame rates with path tracing.

Which GPUs Support Ray Tracing?

Ray tracing in games relies on special hardware, and NVIDIA really set the standard for that with their RTX 20 series back in 2018. They brought in the first RT cores, and every generation since has cranked things up — RTX 30 series doubled their speed, RTX 40 doubled it again and introduced Shader Execution Reordering (which just means smarter ray scheduling), and now the RTX 50 series is out there with even more power. Right now, NVIDIA's latest GPUs give you the best real-time ray tracing out there.

AMD jumped in with their RX 6000 cards and RDNA 2 architecture, which was the first time they added dedicated Ray Accelerators. But honestly, the performance was way behind NVIDIA. AMD improved things a bit with the RX 7000 (RDNA 3), and the new RX 9000 series (RDNA 4) finally brings AMD closer. Still, NVIDIA holds the crown when it comes to ray tracing.

Intel joined the party recently, too, with their Arc Alchemist GPUs. These can handle ray tracing and do a decent job. Their next-gen Arc Battlemage cards are even better. If you're using older cards like NVIDIA's GTX 10/16 series or AMD's RX 5000 series, ray tracing either doesn't work, or it crawls since it runs entirely on software. That's just not worth it.

Bottom line: for a solid ray tracing experience, go for an NVIDIA RTX 3060 or better, AMD RX 6700 XT or better, or an Intel Arc A750 or better. NVIDIA cards tend to give you the most bang for your buck when it comes to ray tracing.

Is Ray Tracing Worth It?

This really depends on your GPU, the game, and what matters most to you. Sometimes, ray tracing makes a game look jaw-droppingly good — Cyberpunk 2077 with path tracing is a perfect example. The lighting feels real in a way no other mode can match. Alan Wake 2, Metro Exodus Enhanced Edition, and Control also use ray tracing to level up their visuals and atmosphere. But in other games, the difference is barely noticeable; maybe some reflections look better, but while you're rushing through the game, you might not even spot them.

Here's a simple guideline: turn on ray tracing if your GPU can keep up with solid frame rates and the game's ray tracing effects genuinely add something. With an RTX 4070 or better, you can run ray tracing at 1440p using DLSS Quality pretty comfortably in most games. For mid-range cards like an RTX 3060 or RX 7600, stick to the lighter RT effects (like just shadows or reflections) and rely on upscaling to keep things smooth. If you play competitive shooters or games where speed and input lag matter, ray tracing isn't worth the hit, no matter what hardware you've got.

Looking ahead, path tracing is quickly becoming the new standard for lighting in games. As GPUs get stronger each year, the performance hit from ray tracing keeps shrinking. Eventually, ray tracing will be just another must-have feature instead of a fancy add-on.

Frequently Asked Questions

Do I need ray tracing for gaming?

Nope. Ray tracing isn't required — most games still look fantastic using traditional rendering techniques. Tons of popular games don't even support it. It's mainly a nice visual upgrade if your hardware can handle it, but you don't lose anything by keeping it off.

Which GPU is best for ray tracing?

Right now, NVIDIA's RTX 50 series has the top ray tracing performance, with the RTX 5090 at the pinnacle. If you want great ray tracing without spending a fortune, check out the RTX 4070 Ti Super or the RTX 5070. On the AMD side, the RX 9070 XT is their best for ray tracing. Still, NVIDIA cards are way ahead when you compare similar prices.

Can AMD GPUs do ray tracing?

Yes, definitely. AMD's RX 6000, 7000, and 9000 series all have hardware support for ray tracing. The RX 9000 cards are much better, but NVIDIA still leads by quite a bit. AMD cards can handle most ray-traced games at medium settings using FSR upscaling.

What is path tracing?

Path tracing is kind of like ray tracing's big brother. It simulates how rays of light bounce and scatter all throughout a scene, making the lighting look especially realistic. It handles every bit of lighting — direct light, indirect bounces, shadows, reflections, ambient occlusion — all through ray tracing. No shortcuts. The result? Visuals that actually look like something out of a movie. Games like Cyberpunk 2077's Overdrive Mode, Alan Wake 2, and Portal RTX show off what path tracing can do. But it's tough on hardware — you need an RTX 4080 or better, and you pretty much have to use DLSS.

Does ray tracing affect FPS a lot?

Yup. Turning on ray tracing usually knocks frame rates down by 30-50%, depending on the game and which ray tracing features you use. When full path tracing is active, performance can drop 60-70% or even more. That's why tech like DLSS and FSR really matter. With DLSS on Quality mode, you're usually only looking at a 10-20% FPS drop, so it's way easier on your system.
