Can My GTX 1660 Super Run RimWorld? FPS Estimate & System Requirements (2026)

The GTX 1660 Super clears RimWorld at 1080p with around 57 FPS — a solid 60+ experience. 1440p needs upscaling to stay smooth. Note that RimWorld is CPU-bound at high frame rates, so on a GTX 1660 Super the processor — not the GPU — decides how high your average FPS actually climbs.

On a GTX 1660 Super, aim for 1080p (Full HD) in RimWorld. The GTX 1660 Super clears RimWorld at 1080p with around 57 FPS — a solid 60+ experience. 1440p needs upscaling to stay smooth. Note that RimWorld is CPU-bound at high frame rates, so on a GTX 1660 Super the processor — not the GPU — decides how high your average FPS actually climbs.

Unlike most titles, RimWorld leans on the processor more than the GTX 1660 Super. At 1080p you can already be CPU-limited, so a faster GTX 1660 Super gives diminishing returns — spend the budget on a stronger CPU or faster RAM. The GTX 1660 Super has more than enough pixel-pushing power for RimWorld.

The limiting factor for this specific pairing is your CPU. RimWorld spends most of its frame budget on the processor (entity counts, physics, draw calls), so the GTX 1660 Super — a entry-level card at relative index 32/100 — rarely reaches its own limit. Upgrading the CPU yields more FPS than upgrading the GPU here.

RimWorld is assigned a hardware-demand tier 5/9 from its published requirements (or release era + genre). Each GPU has a relative-performance index (RTX 4090 = 100, source TechPowerUp). FPS ≈ 60 × (GPU index ÷ required index)^0.85, then scaled ×0.66 for 1440p and ×0.38 for 4K. FPS figures are editorial estimates from a transparent demand-tier model (TechPowerUp relative-performance indices, retrieved 2026-08-29), not benchmarks. Verify with your own hardware.
