Multi Frame Generation (MFG) aims to enhance gameplay smoothness by generating additional frames using AI, with Nvidia's RTX 40-series cards officially supporting up to 2x generation. However, the latest RTX 50-series GPUs are designed for higher rates, potentially up to 6x MFG, thanks to more powerful Tensor cores and a dedicated AI Management Processor. This advancement allows for smoother delivery of both rendered and AI-generated frames.
Despite Nvidia's official limitations, PC gamers have found ways to unlock higher MFG rates on RTX 40-series cards. Using tools like the ReShade HDR Installer, it's possible to enable up to 4x MFG on cards like the RTX 4070 Super, which officially supports only 2x. While Nvidia suggests such unlocks require significant engineering effort, independent testing reveals promising results.
Even officially supported Frame Generation can sometimes introduce visual artifacts like blurry frames or latency issues. Therefore, expectations for an unofficial unlock on an RTX 4070 Super were tempered with caution. The goal was to assess how much performance could be squeezed from existing hardware, potentially delaying costly upgrades.
Performance in Supported Titles
Surprisingly, some games that don't even officially support standard MFG, such as narrative-driven titles like Lost Records: Bloom & Rage and The Thaumaturge, are compatible with the unofficial 4x MFG unlock. Nvidia's official list details games that support MFG, but unofficial mods extend this functionality. It is important to note that these unofficial mods are intended for single-player games only, as they can interfere with anti-cheat systems in multiplayer titles.
Testing was conducted at 1440p resolution with High graphical settings, Nvidia DLSS set to 'Balanced', and ray tracing disabled where applicable. The unofficial MFG was capped at 4x for testing, as not all games can handle the maximum 6x rate, and 4x is seen as a more accessible target for RTX 40-series users.
While Lost Records: Bloom & Rage provided a consistently smooth experience with MFG active, with only minor detected visual differences in distant shadows, other titles presented more challenges. Vampire: The Masquerade - Bloodlines 2, despite boosting frame rates, suffered from noticeable frame hitching and artifacting, particularly when traversing faster. Ghosting was observed during high-speed movement and between elevated positions, suggesting potential latency issues similar to those seen with official MFG implementations.
The Thaumaturge also exhibited ghosting, primarily during conversation-based cutscenes and turn-based combat, though it was more subtle than in Bloodlines 2. The benchmark tool for Cyberpunk 2077 yielded high frame rates with 4x MFG, but the visual experience was often unstable and flickery, also leading to increased GPU temperatures. This suggests that while the hardware may be capable, extensive software tweaking would be necessary for a truly stable experience in demanding titles.
Despite these occasional stability and visual hiccups, the unofficial 4x MFG unlock proved surprisingly viable on the RTX 4070 Super. Many games required minimal setup beyond installing the necessary mods through the ReShade HDR Installer, with options readily available in in-game settings. Even demanding titles like Pragmata could be made to run with MFG, though higher VRAM might be needed for optimal visual fidelity alongside it.
While extended play sessions might reveal further issues, the current findings suggest that the RTX 4070 Super retains significant potential. The ability to unlock higher MFG rates, even unofficially, demonstrates that the card has considerable life left, potentially postponing the need for an expensive upgrade for several more years.
