3 performance mods for South of Midnight that will improve overall gameplay
1) Ultimate Engine Tweaks (Anti-Stutters - More Performance - Lower Latency - Better Clarity - Lossless) by P40L0

The creator of this South of Midnight performance mod defines it as:
"Definitive Unreal "Engine.ini" changes with the goal to remove most stutters, improve performance and stability, decrease input latency, and improve picture clarity. All with no visual loss."
The goal of this mod is to add as many optimizations as possible (both for CPU/GPU/RAM/SSD) to remove stuttering, improve performance, reduce input latency and improve picture clarity (e.g. by removing Film Grain & Chromatic Aberration, optimize DLSS/FSR upscaling and more) without any visual loss nor introducing glitches or crashes.
2) Perfection by dragoncosmico

The creator of this South of Midnight performance mod defines it as:
"Performance friendly. Needs access to depth buffer."
The mod will introduce the following shaders to your version of South of Midnight:
- Saturation-based Bloom and DOF
- Realistic Palette Shader
- ColorExposure Shader
- LongAA
- TAA Shader Pack
- Dithering Reshade Shader
3) South of Midnight Stability and Performance Configs by AIorro

The creator of this South of Midnight performance defines it as:
"Optimized Engine.ini for South of Midnight. Two versions: Mid-range boosts performance and clarity with DLSS/FSR; Low-end (4 GB VRAM) cuts stuttering and lag on weaker PCs. Both disable VSync and film grain for smooth, sharp gameplay."
The goal of this mod is to breathe life into your gaming experience. There are two options for you to choose from, depending on your setup.
The mod aims to do the following:
- Mid-Range Version: Targets stuttering, input lag, and blurry visuals with a full optimization suite for CPU, GPU, RAM, and SSD. Expect fluid gameplay and fast load times.
- Low-End Version (4 GB VRAM): Strips down resource demands for weaker PCs, slashing lag and stutter while keeping the game playable — no fancy extras, just raw survival.
- Both versions banish VSync and film grain, ensuring South of Midnight’s eerie charm shines through without hiccups.
Key adjustments
Renderer:
- Mid-Range: VSync off, film grain and chromatic aberration gone, DLSS/FSR added for compatible GPUs—performance meets clarity.
- Low-End: Same cuts to VSync and effects, but skips upscaling to save VRAM.
Textures:
- Mid-Range: VRAM pool at 70% for balanced memory use.
- Low-End: Tighter texture streaming for 4 GB VRAM systems — every byte counts.
Async everything: Multi-core CPU magic via async compute, physics, and shaders — full power for mid-range, dialed back but effective for low-end.
Future-proofing: Mid-range keeps Nanite and virtual shadows; low-end skips them to stay lightweight.
Humor: Witty comments in both files — because even optimization deserves a chuckle.
