Now, with the addition of DLSS 3.5 technology, players will be able to utilize AI-driven ray tracing reconstruction techniques to enhance the realism of ray tracing and improve the responsiveness of dynamic lighting effects. Furthermore, the introduction of NVIDIA RTX IO has boosted texture loading speeds and reduced the size of game files. This upgrade not only revitalizes the RTX version of "Portal" but also reaffirms its creative and enduring appeal as a sci-fi puzzle game.

Enhanced with panoramic ray tracing effects, RTX Remix tools are also part of the upgrade. a14a1512-be14-46c7-abba-85b8b9627b8d.jpg In the original "Portal" RTX version, the game incorporated NVIDIA's ray tracing technology, also known as path tracing, aiming to create an immersive gaming world for players. This technology accurately simulates the properties of light in the real world, bringing realistic lighting, shadows, reflections, and refractions to surfaces and objects in the game. Every object in the game, including floors, walls, etc., has been redesigned to showcase more realistic material details, such as the reflection of glass and the gloss of metal. These improvements not only make the game's levels and effects appear more detailed and dynamic but also allow players to experience realistic changes in lighting and shadows, greatly enhancing the game's realism and immersion. afd9fdef-28d3-43c2-b8f2-6a2460b51540.jpg The official development team also utilized the RTX Remix tool to completely overhaul the game, meticulously adjusting every pixel to ensure that the floors, walls, and various objects exhibit a more realistic texture and reflection effects. This application of new technology enables the RTX version of "Portal" to achieve more intelligent and detailed global illumination methods as well as other ray tracing effects. Additionally, physics-based rendering technology adds realism to objects in the environment, with details such as surface scratches, wear and tear, and rivets clearly visible, while maintaining a balance of clinical and simplicity in the portal laboratory to ensure that players can easily identify interactive surfaces and portal placements. This remaster is not only a heartfelt reimagining of the original, but also a demonstration of the potential of RTX Remix mode. This automated tool is nearly as advanced as the sci-fi portal gun in the game, employing a combination of AI, hardware, and software to add ray tracing capabilities to any game.

Live Testing Results

Next up are the results from live testing of the game. To evaluate the performance of Portal RTX in real gameplay scenarios, two graphics cards from GearUp, the GearUp GeForce RTX 4070 SUPER Snowstorm Mini and the GearUp GeForce RTX 4080 SUPER Radiance OC, were selected for this test. These two cards represent GearUp's 2K and 4K level graphics cards respectively. Not only do they boast excellent performance, but their sleek designs also provide players with an intuitive display of performance. The tests will be conducted at the highest graphics settings, covering three resolutions: 1080P, 2K, and 4K. Additionally, frame rate changes will be recorded by toggling DLSS 3.5 technology on and off in different modes. Furthermore, real-time game screenshots will be provided for a visual comparison of the graphics quality.

Frame Rate Testing at 1080P Sbead3377-e318-4094-98dc-248895c1cd13.png First, let's start with the 1080P resolution test. As a remastered game with demanding hardware requirements, without DLSS 3.5 enabled, the game's frame rates aren't particularly high, with both GPUs only reaching an average of 33.52 frames and 43.55 frames, respectively. However, once DLSS 3.5 is enabled, there's a significant boost in frame rates, delivering smooth and stable gameplay even at the highest graphics settings. In auto mode, the frame rates for the Gainward GeForce RTX 4070 SUPER SnowStalker Mini can maintain a stable average of 117.46 frames, while the Gainward GeForce RTX 4080 SUPER Aurora OC surpasses the 150 frames mark on average.

Next up, 2K resolution. Sea54d87b-0d2f-4b25-833c-32f3a0296444.png Moving on to the 2K resolution test. With DLSS 3.5 turned off, the average frame rates for both GPUs further dropped to 19.38 frames and 25.3 frames respectively. Upon enabling DLSS 3.5, there's a noticeable improvement in overall smoothness. The framerate for the Gainward GeForce RTX 4070 SUPER Snow Stomper Mini remains stable at an average of 84.43 frames. Meanwhile, the Gainward GeForce RTX 4080 SUPER Glittering OC still exceeds an average of 100 frames, reaching an impressive average of 116.57 frames.

4K Sfe3b8e87-73cb-4f4b-9c3b-1f520085fc7b.png In the final 4K resolution test, we observed that the Gainward GeForce RTX 4070 SUPER SnowStomp Mini, with DLSS 3.5 enabled, achieved an average of 50.91 frames per second (FPS), but couldn't maintain smooth gameplay throughout. On the other hand, the Gainward GeForce RTX 4080 SUPER GlitterBeam OC lived up to its 4K graphics card status, maintaining an average of 74.05 FPS, ensuring smooth gaming experience.

The test results indicate that "Portal" RTX version demands high GPU performance. However, thanks to the support of DLSS 3.5 technology, both Gainward graphics cards demonstrated significant performance advantages in the game. Whether at 1080P or 2K resolution, players can enjoy high frame rates and smooth gameplay, while also experiencing outstanding visual effects. Even when facing 4K resolution, the Gainward GeForce RTX 4080 SUPER GlitterBeam OC can maintain smooth gameplay.
