Slay the Spire 2 benchmark on GTX 1660: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Slay the Spire 2 FPS with a GTX 1660 and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 131FPS min 81Excellent | 76FPS min 59Good | 29FPS min 26Poor |
| High | 170FPS min 105Excellent | 99FPS min 76Good | 38FPS min 34Acceptable |
| Medium | 222FPS min 136Excellent | 129FPS min 100Excellent | 49FPS min 43Acceptable |
| Low | 288FPS min 177Excellent | 167FPS min 129Excellent | 64FPS min 57Good |
| Bottleneck (estimated) | CPU 44% | CPU 17% | GPU 54% |
The percentage estimates how much of the stronger component's capability goes unused because of the other one.
This one does matter: from the Intel Core i9-14900K downwards the processor becomes the brake on the GTX 1660. There is 19% 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 Slay the Spire 2 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 with FSR enabled, starting from its native Ultra FPS.
| Resolution | Native | FSR Quality | FSR Performance |
|---|---|---|---|
| 1080p | 131 | 164 | 190 |
| 1440p | 76 | 103 | 125 |
| 4K | 29 | 42 | 54 |
About ray tracing: every figure on this page is with ray tracing off. The GTX 1660 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 has headroom to spare in Slay the Spire 2: 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 Enough for Slay the Spire 2?
The GTX 1660 delivers 131 FPS at 1080p Ultra in Slay the Spire 2. More than enough for 144Hz. You can comfortably play at 1440p.
At 1440p it gets 76 FPS and at 4K 29 FPS at Ultra quality.
This GPU is more than enough — you can play at 1440p or 4K comfortably
