37 frames to 75 frames! Player hand rubbing algorithm: GTX 1660 fun to play "Flute of Time"

Fast Technology November 11th news, recently players vandolin12345 on a set of GTX 1660 graphics card and i5-9400F processor as the core of the old platform, the Switch 2 version of the "Legend of Zelda: Flute of Time" successfully increased the operating frame rate from 38 frames to about 75 frames, to achieve double the performance leap.

Previously, during preliminary testing with the Fritchii 5.5 simulator, the player found that even at 1080p resolution, the old GTX 1660 was only able to maintain a level of around 38 frames in the forest area of Kokiri at the beginning of the game.

Even if the FXAA and internal antialiasing channels are turned off, the frame rate can only barely increase to 41 frames, which is obviously unacceptable for enthusiasts pursuing fluency.

In subsequent tests, the player found that the emulator's built-in so-called FSR 3 option had nothing to do with AMD technology, but a self-developed frame interpolation system that was disabled by the developer because it would cause severe flicker.

To put it bluntly, this is a pseudo-frame generation scheme. So he reconstructed the simulator with Fable 5.2 and rewrote the logic of the algorithm, changing the logic that originally tracked only a few pixels to full-frame area tracking.

The actual measurement shows that after this underlying reconstruction, the real-time display frame rate of the game has successfully jumped to 73-77 frames. Although this frame insertion-based scheme does not reduce the operation delay, the picture smoothness has been improved qualitatively, and the obvious ghosting and blurring phenomena that were originally at low frame rate have basically disappeared.

Finally, in order to enhance the cross-platform experience, the player also deeply customized the controller icon through Python scripts and FontForge tools: using zstd decompression technology to extract game resources and redraw the original Switch button icon to a more familiar Xbox ABXY layout for PC players.

At present, this optimization scheme has passed the stability test under the display environment of 1080p/144Hz. Although the picture effect is extreme, because this involves modification of the underlying source code, this scheme can only be run on a specific version of the Fritchii simulator.
