On a NVIDIA GTX 660 (2GB) (paired with a balanced AMD Ryzen 3 3300X-class CPU), The Callisto Protocol runs at roughly 23 FPS at 1080p with our optimized settings — up from about 11FPS with everything maxed. Here's the configuration and what each setting costs.
The NVIDIA GTX 660 (2GB) is a entry-level graphics card with 2GB of VRAM, and The Callisto Protocol is a demanding, graphically heavy game. Paired with the AMD Ryzen 3 3300X, it is a real challenge at 1080p — about 23 FPSwith FrameCoach's optimized settings, a clear jump from roughly 11 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. The Callisto Protocol offers ray tracing, but the NVIDIA GTX 660 (2GB) isn't built for it, so we leave it off. With only 2GB of VRAM, keep textures a notch below max in The Callisto Protocol 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 | 11 | 23 |
| 1440p | 6 | 14 |
| 4K | 4 | 8 |

With FrameCoach's optimized balanced settings, the NVIDIA GTX 660 (2GB) averages around 23 FPS at 1080p in The Callisto Protocol — up from about 11 FPS with everything on High.
At 1440p with optimized settings, the NVIDIA GTX 660 (2GB) averages roughly 14 FPS in The Callisto Protocol; 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 Screen Space Reflections 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.
