RUNNING TRAIN | 走ル列車！ is arguably the most visually breathtaking railway simulator ever released, but its Unreal Engine 5 foundation can bring even high-end hardware to a grinding halt. If you are struggling with frame drops during a heavy Snowy Winter run on the Sankai Main Line, you need a precise optimization strategy to keep your simulation smooth. Here is the definitive guide to the best graphics settings Running Train players can use to lock in a flawless 60 FPS without sacrificing the hyper-realistic Japanese scenery.
Why the Best Graphics Settings Running Train Demand UE5 Tuning
Developed by solo studio Novatetsu Games and released in Early Access on May 24, 2026, RUNNING TRAIN utilizes the cutting-edge Unreal Engine 5. This means it relies heavily on next-generation rendering technologies like Lumen for global illumination and Virtual Shadow Maps (VSM) for realistic dynamic shadows. While these features make the 40km of meticulously handcrafted Japanese rural railways look photorealistic, they are notoriously heavy on GPU resources.
According to the developer's own hardware notes, a baseline workstation equipped with an RTX 3060 can run the game at 40-50 FPS on native 1080p with maximum settings. However, by disabling Lumen and activating DLSS Upscaling, that same RTX 3060 can leap to 70-90 FPS with minimal visual degradation. Finding the best graphics settings Running Train has to offer is all about balancing this UE5 Engine Performance Scaling. You don't need a massive RTX 4090 to enjoy the Coastal Hayamori Railway; you just need to understand which sliders impact rendering the most.

Core Optimization: The Best Graphics Settings Running Train for 60 FPS
To achieve a stable 60 FPS across both the local and express train diagrams, you need to adjust the core UE5 parameters. The game features highly detailed train cabs, meaning both the interior and the exterior world are rendered with immense fidelity. Here is the optimal configuration for mid-range to high-end systems:
| Graphics Setting | Recommended Value | FPS Impact (Ultra vs Rec) | Visual Difference |
|---|---|---|---|
| Global Illumination | Screen Space | +25% | Noticeable in tunnels, minor outdoors |
| Anti-Aliasing | DLSS / FSR (Quality) | +30% | Minimal (slight ghosting on wires) |
| Shadow Quality | High | +10% | Indistinguishable at high speeds |
| Foliage Density | High | +15% | Fewer distant trees on Rural Kofuku |
| Post-Processing | Medium | +8% | Less aggressive motion blur |
- Global Illumination: Set to Screen Space (or High instead of Epic). Lumen Illumination is the biggest performance killer in RUNNING TRAIN. Disabling it reclaims roughly 25% of your frame rate.
- Anti-Aliasing & Upscaling: Set to DLSS (Quality or Balanced). If you are on an AMD card, use FSR. DLSS Upscaling Active is mandatory for hitting that 70-90 FPS target on mid-range cards.
- Shadow Quality: Set to High. Dropping shadows from Ultra to High reduces the VRAM load caused by Virtual Shadow Maps, especially when passing through dense stations on the Fukugawa Line.
- Post-Processing: Set to Medium. This reduces the cost of volumetric fog and motion blur, which can cause micro-stutters when traveling at high speeds.
- Foliage Density: Set to High. The Rural Kofuku Railway is packed with trees and grass. Ultra foliage forces the engine to draw millions of individual leaves at a distance.
Inside the cabin, the simulation runs deep. The game includes 4 distinct train types with different operational characteristics. The older commuter trains have analog gauges that require less rendering power than the modern express trains equipped with digital glass cockpits. The Master controller physics run smoothly even on medium CPU settings, but the sheer amount of glass means reflection quality matters. Disabling the Vigilance system UI overlay saves minor rendering overhead, but the real trick is managing window reflections. Window reflections from the Fukugawa Line scenery require high shader cache, so ensure your GPU drivers are fully updated. Furthermore, volumetric fog inside the cab can be disabled for an instant FPS boost without ruining the immersion.

Fixing Stutters on the Sankai Main Line and Coastal Hayamori Railway
The game currently features over 40 diagrams spanning two distinct fictional operators. The Fukugawa Line consists of 10 shorter routes (roughly 12-minute routes each), which generally perform well. However, the Sankai Main Line is a different beast entirely. With 32 routes of varying lengths and complex track switching, the Performance Load Analysis of this specific line reveals severe CPU and GPU bottlenecks.
When driving the express train along the Coastal Hayamori Railway, the engine has to stream in high-resolution water textures and distant mountain meshes simultaneously. This 40km of track is beautiful, but the streaming load can cause traversal stutters. To mitigate this, you must install RUNNING TRAIN on a fast NVMe Gen4 SSD. Mechanical HDDs or older SATA SSDs simply cannot load the Unreal Engine 5 assets fast enough, leading to hitching when entering a new sector.
Additionally, the environmental assets heavily dictate performance. The Sakura Spring Assets account for roughly 35% of the visual processing load in certain rural sections due to the complex geometry of the cherry blossom trees. If you are experiencing heavy drops specifically during these seasonal runs, lowering the Draw Distance from Epic to High will prevent the engine from rendering these complex assets before you can even see them clearly.

Advanced Tweaks: Pushing the Best Graphics Settings Running Train Beyond Ultra
For players who want maximum visual fidelity without the stuttering, we have to look beyond the in-game menus. The weather systems in RUNNING TRAIN are incredibly dynamic. While baseline 12-minute routes run perfectly on a clear day, the introduction of precipitation changes the math.
During a Sakura Spring run, the petal particle systems add 15% GPU load. This is because each petal interacts with the train's lighting and motion blur. Similarly, during a Snowy Winter blizzard, the heavy snow drops frames by 20% as the engine calculates the accumulation and the windshield wiper physics. To combat this, advanced users can modify the Engine.ini file located in the local AppData folder.
By adding specific Unreal Engine 5 console variables, you can force the game to optimize its particle rendering:
[SystemSettings]
r.Lumen.Reflections.Allow=0
r.VolumetricFog.GridPixelSize=16
r.Shadow.DistanceScale=0.8
These tweaks reduce the resolution of the volumetric fog grid and scale back the shadow rendering distance just enough to maintain a locked 60 FPS during heavy snowstorms.
Another crucial aspect of the best graphics settings Running Train offers is managing the open livery editor. Custom textures loaded into the game are uncompressed by default. If you download 4K community liveries, your VRAM usage will spike, leading to severe stuttering regardless of your core settings. Stick to 2K textures for AI trains and only use 4K liveries for your player-controlled train to keep VRAM usage below 8GB. This hybrid approach is the absolute best configuration for hardcore simulation fans.

Frequently Asked Questions (FAQ)
What are the minimum system requirements for RUNNING TRAIN? The absolute minimum is a modern quad-core CPU, 16GB of RAM, and a GPU equivalent to an NVIDIA GTX 1060 or RTX 3050 laptop GPU. However, to maintain 30 FPS on these systems, you must use medium settings and aggressive upscaling.
Why does RUNNING TRAIN stutter when approaching stations? This is a classic Unreal Engine 5 shader compilation and asset streaming issue. Moving the game to an NVMe Gen4 SSD and lowering the "Draw Distance" setting to High will significantly reduce station approach stutters.
Can I run RUNNING TRAIN in VR? While native VR is not fully implemented yet, the community has successfully used the UEVR Mod by Praydog to play the game in VR. Be warned: VR requires rendering the game twice, so you will need a top-tier GPU (like an RTX 4080 or 4090) and must rely heavily on DLSS. Because RUNNING TRAIN uses advanced Lumen lighting, running it in VR can easily consume over 16GB of VRAM. If you attempt this, setting Global Illumination to Screen Space is non-negotiable.
Does turning off the UI improve performance? Yes. Disabling the UI (including the speedometer and Vigilance system overlays) not only grants you extra score points in Hard-Mode but also slightly reduces CPU overhead, resulting in smoother frame pacing.
