Since its release at the start of September, Nvidia's DLSS 5 has been the subject of growing concerns, following a series of negative reports. One recent incident involved a graphics card failing during gameplay, with the user blaming the issue on DLSS 5, Nvidia's advanced upscaling technology. The situation was first shared by a Reddit user named wax469 on the r/RTX5080 forum and later uncovered by VideoCardz this weekend. The user's PC, which cost several thousand euros, had been running smoothly for a month with an AMD Ryzen 9 9950X3D processor and an MSI GeForce RTX 5080 Ventus 3X. The RTX 5080, priced at 1179 euros, was previously regarded as the best option for 4K gaming. The user decided to test DLSS 5, which uses generative AI to create images rather than simply enlarging them. After about five minutes of gameplay at 80 frames per second, the screen began flickering violently. The system then shut down completely and could not be restarted with the card installed. Further testing revealed that the issue was with the graphics card itself. Switching to the integrated graphics on the Ryzen processor allowed the PC to start normally. Reinstalling the RTX 5080 caused the same problem again. Eventually, the user received a replacement card of the same model, which has been functioning properly since then. DLSS 5 is currently supported by only one game, NBA 2K27. To use it in other titles like GTA V, users must employ a "homemade injection," an unofficial method that Nvidia did not design or test. This is far from standard usage. The video shared by the user shows image corruption typical of a failing video memory. The RTX 5080 uses eight modules of GDDR7 memory, and a single faulty module can cause such visual issues. On the Reddit thread, many users believe the card may have been defective from the factory, and the stress of using DLSS 5 simply exposed the problem earlier. DLSS 5 is also known for its high power consumption, which has previously caused issues, including melting 16-pin connectors on certain RTX 5090 cards during official tests. However, the link between DLSS 5 and the failure of the RTX 5080 remains a theory. The situation differs from the RTX 5090 incident, where the connector melted during an official test without any modifications. In the case of the RTX 5080, the issue arose through an injection that Nvidia had not anticipated, which may affect how responsibility is assigned. Nvidia has stated that DLSS 5 will eventually be available on the GeForce RTX 40 series once it is better optimized. AMD is also preparing its own solution, a neural rendering technology for its upcoming graphics cards. For now, a single isolated incident does not indicate a widespread problem, and there is no direct evidence linking DLSS 5 to the failure of these cards. However, caution is still advised when using unofficial methods, especially given the rising prices of graphics cards. The safest approach is to wait until DLSS 5 is officially supported in games before attempting to use it through unofficial means. This ensures both better performance and reduced risk of hardware issues.
