Nvidia DLSS 4.5: Old GPUs Get New Life!
13 Jan
Summary
- DLSS 4.5 can upscale 240p game footage to 720p.
- New DLSS version runs on all RTX cards with Tensor cores.
- AI upscaling still struggles with thin lines and fences.
Nvidia's DLSS 4.5, featuring a second-generation Transformer model, is proving remarkably adept at dynamic upscaling. It not only smooths errors in high-resolution play but also excels at enhancing games rendered at extremely low resolutions. Gamers have demonstrated the technology's power by upscaling titles like Hellblade II from 720p to 4K with impressive clarity, and even transforming a 240p render of Elder Scrolls IV: Oblivion into a functional 720p experience.
The new DLSS 4.5 Transformer models are compatible with any RTX card possessing Tensor cores, dating back to the RTX 2060 series up to the latest RTX 5090. This broad compatibility offers a significant upgrade path for users with older hardware, enabling them to achieve playable frame rates in games that were previously unplayable at higher resolutions.
While DLSS 4.5 represents a major leap, it is not without its limitations. The upscaler's effectiveness is bound by the input quality, leading to smudged or disappearing thin lines like telephone wires and mesh fences, particularly during motion. Nevertheless, Nvidia anticipates continuous improvement with its transformer models, suggesting that entry-level gaming visuals could see considerable enhancement in the future.
