On a AMD Radeon Vega 10 (iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Marathon runs at roughly 23 FPS at 1080p with our optimized settings — up from about 10FPS with everything maxed. Here's the configuration and what each setting costs.
The AMD Radeon Vega 10 (iGPU) is a entry-level graphics card with 2GB of VRAM, and Marathon is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 23 FPSwith FrameCoach's optimized settings, a clear jump from roughly 10 FPS with everything on High.
Across resolutions you can expect around 23 FPS at 1080p and 14 FPS at 1440p, dropping to roughly 8 FPS at 4K. With only 2GB of VRAM, keep textures a notch below max in Marathon at higher resolutions to avoid stutter. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 10 | 23 |
| 1440p | 6 | 14 |
| 4K | 3 | 8 |

With FrameCoach's optimized balanced settings, the AMD Radeon Vega 10 (iGPU) averages around 23 FPS at 1080p in Marathon — up from about 10 FPS with everything on High.
At 1440p with optimized settings, the AMD Radeon Vega 10 (iGPU) averages roughly 14 FPS in Marathon; turn on upscaling or aim for a locked 60 for the best feel.
Turn on FSR (Balanced), keep ray tracing off for maximum FPS, and ease the heaviest options like Shadow Quality and View Distance down a notch. The full per-setting breakdown is above.
FPS figures are estimates from a generalized model (hardware tier × game load × per-setting weights), not live benchmarks — real performance varies by scene, drivers and game version.
