The percentage estimates how much of the stronger component's capability goes unused because of the other one.

This one does matter: from the AMD Ryzen 7 9800X3D downwards the processor becomes the brake on the GTX 1660 Ti. There is 22% between the slowest and fastest CPU in the table. One caveat: this is at 1080p, where the CPU weighs most. At 1440p and 4K the graphics card takes over and the processor stops mattering.

FSR performance: FPS with AI upscaling

Upscaling renders Subnautica at a lower internal resolution and reconstructs the image, so you trade a little sharpness for extra frames. These are the estimated figures for the GTX 1660 Ti with FSR enabled, starting from its native Ultra FPS.

1440p577794
4K223241

About ray tracing: every figure on this page is with ray tracing off. The GTX 1660 Ti has no dedicated hardware for it, so it is an option best left disabled.

Estimated figures. The real gain varies by game and by the version of the technology.

Is the CPU or the graphics card holding you back?

These FPS assume a mid-range CPU that isn't a bottleneck — roughly a Intel Core i5-13400 — and 16 GB of RAM.

With that CPU, the GTX 1660 Ti has headroom to spare in Subnautica: the processor runs out before the graphics card does. A faster processor would gain you FPS; a stronger graphics card would barely help. At 4K it flips: there the graphics card becomes the limit.

Is the GTX 1660 Ti Enough for Subnautica?

Frequently asked questions about Subnautica on the GTX 1660 Ti

How many FPS does the GTX 1660 Ti get in Subnautica at 1080p?
The GTX 1660 Ti averages 90 FPS in Subnautica at 1080p on Ultra settings. Dropping to High takes it to around 116 FPS, and Low reaches roughly 197 FPS.
What about 1440p and 4K?
On Ultra, the GTX 1660 Ti manages around 57 FPS at 1440p and around 22 FPS at 4K. Those are native figures: switching on AI upscaling lifts both considerably.
Can the GTX 1660 Ti run Subnautica at 60 FPS?
Yes. On Ultra settings the GTX 1660 Ti averages above 60 FPS in Subnautica at 1080p. At higher resolutions you can claw back smoothness by lowering the preset or turning on upscaling.
Do these Subnautica figures include upscaling or ray tracing?
No. Every FPS figure on this page is native, with no AI upscaling and with ray tracing off. The GTX 1660 Ti has no ray tracing hardware, so that option is off the table for this card.
How many FPS do I gain by turning on FSR in Subnautica?
At 4K, FSR on Quality mode takes the GTX 1660 Ti from around 22 native FPS to an estimated 32 FPS. Performance mode goes higher still, at the cost of some image sharpness.
What processor do I need to pair with the GTX 1660 Ti?
The figures on this page assume a Intel Core i5-13400, a mid-range processor that does not bottleneck the card. What matters with the GTX 1660 Ti is that the CPU is not far below it: past that class, moving up a processor barely changes FPS at higher resolutions.
