Stutters/fps drop - fix (almost)

[openheartbadpro-boop]

I was having an issue where the game would freeze every 10–30 seconds, and the frametime graph was extremely unstable.
However, by changing a few settings, I managed to almost completely (about 99%) eliminate these annoying stutters. They still occur occasionally, but much less frequently—around once every 10–20 minutes. This is no longer critical and finally allows me to enjoy the gameplay.
Here are the settings I used:

In the Display menu:
• Frame Output: V-Sync
• Window Scaling: Bilinear
• NVIDIA DLSS/DLAA: OFF
• Anti-Aliasing (FXAA): OFF
In the Advanced menu:
•GPU Frame Preparation in Separate Thread: ON
• Windows Timer (1ms): OFF

In the totk.ini file (located in the game's root folder, next to totk.exe), change the value from 0 to 1 (or vice versa, depending on what works best for you; it works with 1 for me):
ini

replay_async = 1

replay_async = 1

The image is not as sharp and clean, but these visual flaws are completely outweighed by the smooth gameplay. While DLSS/DLAA makes the graphics look much better, it introduces stutters every few dozen seconds.
I have attached screenshots—please pay attention to the 1% low and 0.1% low metrics in hardware-heavy scene.
