NVIDIA’s RTX Remix was recently used to bring ray tracing to Half-Life 2 in a bid to show its potential for improving old video games. While it shows how great these tools can be, it also confirms that remastering a game is not just about flipping a switch to turn on ray tracing.
Features like ray tracing and AI seem promising for remastering, but there’s still a lot to figure out before they can be fully trusted.
Half-Life 2 Proves NVIDIA Needs More Than Ray Tracing
The Half-Life 2 RTX Remix demo is a community project that uses NVIDIA’s RTX Remix technology and unintentionally demonstrates how challenging it can be to upgrade older games with new visual effects, specifically real-time ray tracing. The demo features two levels, Ravenholm and Nova Prospekt, showing the benefits and drawbacks of giving a game made in 2004 a modern look by switching out the lighting technology.
The differences in visuals between the RTX Remix version and the original game are striking. The upgraded textures, models, and environmental details make the game look more advanced and immersive for a modern audience. However, the improvements aren’t just due to ray tracing; the carefully designed assets and higher polygon counts also make the game look more realistic.
Some issues remain, though, like artifacts and noise, especially in reflective areas. This shows that current technology for cleaning up these visuals still needs some work. From a technical standpoint, the demo is very demanding; even powerful NVIDIA RTX 30- and 40-series graphics cards can struggle to maintain smooth performance at higher resolutions without using DLSS.
The Half-Life 2 RTX Remix demo shows that while ray tracing can make games look incredible, it’s not an easy fix for remastering older titles. It requires careful thought about the quality of assets, a team to design the levels, and optimization strategies to maintain performance and avoid visual problems.
Nowhere was this more obvious than in sections of Ravenholme, an abandoned mining town that was known for its spooky atmosphere, dim lighting, and zombies lurking at every corner. RTX Remix made quite the mess of this area, resulting in overly bright lighting that destroyed the atmosphere of the original level. It’s further proof that tools like RTX Remix still require the care and attention of humans in order to stay true to the original vision.
The visual improvements are clear, but the high-performance costs and remaining issues show that although NVIDIA’s path-tracing technology is powerful, it still needs more development before it can easily transform older games into modern ones.
Remasters Need More Than Just Looks
A successful game remaster involves more than just better graphics. While updating visuals can improve the experience, ignoring other important aspects can lead to a remaster that disappoints. For example, Half-Life 2 RTX Remix showcases this idea with its impressive ray-traced graphics. However, if it mainly focuses on looks, it might miss out on other key components that make a remaster fun to play, which currently needs a team to do.
Gameplay mechanics are central to what makes a game fun. A remaster should keep the core mechanics that fans love while refining outdated elements. Any changes should make the gameplay better without changing the overall feel of the game. Half-Life 2 RTX Remix sticks closely to the original gameplay, but changes in lighting and visuals could unintentionally impact how players move, see, and fight. For instance, overly bright lighting in certain areas could ruin the suspense or change how players approach enemies.
This is why a team is still needed for remasters. Many games are dated and need new changes for a modern age that goes further than just pretty sunrays. Level design is crucial and can greatly impact a remaster’s quality. The layout, object placements, and flow of levels are key to creating an engrossing experience. Half-Life 2 RTX Remix concentrates primarily on visuals and may have missed whether these upgrades keep the original playability and intuitive navigation intact.

Remasters and Remakes Are Good for Gamers, Here’s Why
Studios aren’t wrong for leaning on old games.
Sound design is another vital aspect that is often overlooked. The original game’s music, background noise, and sound effects contributed to its unique mood and immersion. It is debatable whether a remaster needs to maintain the core essence of the original sound or carefully recreate it instead of just replacing it with new sounds, but sound is overall important.
These overlooked details have to be considered because if you have a great-looking game with awful sound, it hurts the overall quality. Right now, these are all jobs that are above what AI and ray tracing can do.
RTX Remix Is the First Major Step Forward
Admittedly, RTX Remix and ray tracing are groundbreaking tools for making older games look better. It makes it easier for modders to improve graphics. Ray tracing is also a great way to make a game look better quickly, and it’s easy to see the appeal.
Unlike older tools that require a lot of technical knowledge and manual work, RTX Remix uses artificial intelligence to automate many of the difficult tasks needed for visual upgrades. It has three main features: improving assets with AI, adding realistic lighting through path tracing, and supporting DLSS 4 tech for better performance.
The AI asset-boosting feature allows RTX Remix to analyze a game’s original graphics—like textures and models—and automatically upgrade them to higher quality. This saves modders a lot of time and effort, making it possible for non-skilled artists to improve the visuals. It also makes sure that the updated graphics look realistic by using physically-based rendering materials.
The second key feature, path tracing, uses advanced techniques to simulate how light behaves in the real world, creating much more realistic lighting effects compared to older methods. This technique has been tough for modders to implement before, but with RTX Remix, it’s now easily available for classic games.
DLSS 4 was used in the Half-Life 2 demo to help improve gameplay performance through smart frame generation and upscaling. These features will likely be part of the steps to create impressive, high-quality remastered versions of games.
NVIDIA Is the Trailblazer for This Technology
NVIDIA’s RTX Remix shows the company is making big improvements in using real-time ray tracing for remastering games. However, compared to other game studios, there’s a noticeable difference in how advanced their technology is and how it’s being used.
The Half-Life 2 demo is a great example of this. NVIDIA is using its AI tools to make the process of updating game graphics easier and integrate path tracing effectively. This allows those making remasters to improve the visuals while keeping the original gameplay intact.
Other studios have taken different approaches with mixed results. Some studios decide to modernize their older games with brand-new remakes, like the Demon’s Souls remake. This involves improving gameplay, audio, and visuals through extensive rebuilding of the game assets. While many players would prefer a remake to bring beloved games into the modern age, they often need a lot of time and money to develop. This process involves starting from scratch on many parts of the game, which leads to a much more polished but pricier final product.
On the other hand, some studios opt for smaller visual improvements, mainly improving textures and using upscaling technologies without fully adopting real-time ray tracing. This method results in visuals that are not as impressive as NVIDIA’s work or the Demon’s Souls remake, but it requires less time and resources, making it more viable for a broader range of games and systems.

What’s The Difference Between a Game Remake and Remaster?
Similar words, with very different meanings.
The downsides to this simpler approach are noticeable; even though the texture quality is better, the lighting and shadows often look basic and lack the realism that path tracing can provide. The recent Resident Evil 4 remake shows some ray tracing, but its use is inconsistent and sometimes even harms the game’s atmosphere.
Right now, using real-time ray tracing in gaming isn’t as viable as so many people make it out to be. It demands a lot of computing power, meaning you need powerful hardware to run it smoothly, especially at higher resolutions. While technologies like DLSS can help with performance issues, they might create visual artifacts and reduce overall quality.
When deciding whether to use real-time ray tracing, developers must carefully weigh the impressive visuals against the high costs, performance challenges, and potential trade-offs in other game features. The gaming industry is still figuring out how to best use the feature, and while ray tracing is a way bigger deal than many think, it’s not the magic solution just yet.
While we put a ton of stock into certain techniques and AI, the Half-Life 2 demo shows there’s still such a long road ahead. Even with ray tracing becoming a standard feature, it’s not just a switch. Many game studios have different ideas of how ray tracing should be used.
For now, it feels like the magic solution will be multiple tools working together instead of just one, but we’ll have to wait to see what those tools will eventually be.
