Slay the Spire 2 benchmark on RTX 3090: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Slay the Spire 2 FPS with a RTX 3090 and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 372FPS min 175Excellent | 327FPS min 161Excellent | 253FPS min 139Excellent |
| High | 484FPS min 227Excellent | 426FPS min 210Excellent | 329FPS min 181Excellent |
| Medium | 500FPS min 235Excellent | 500FPS min 247Excellent | 430FPS min 237Excellent |
| Low | 500FPS min 235Excellent | 500FPS min 247Excellent | 500FPS min 275Excellent |
| Bottleneck (estimated) | CPU 69% | CPU 65% | CPU 55% |
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 RTX 3090. There is 6% 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.
DLSS 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 RTX 3090 with DLSS enabled, starting from its native Ultra FPS.
| Resolution | Native | DLSS Quality | DLSS Performance |
|---|---|---|---|
| 1080p | 372 | 465 | 539 |
| 1440p | 327 | 441 | 540 |
| 4K | 253 | 367 | 468 |
About ray tracing: every figure on this page is with ray tracing off. The RTX 3090 does have dedicated hardware for it, so you can turn it on in games that implement it. The FPS cost swings widely depending on how much ray tracing each title uses, and DLSS is exactly what people lean on to pay for it.
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 RTX 3090 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.
Is the RTX 3090 Enough for Slay the Spire 2?
The RTX 3090 delivers 372 FPS at 1080p Ultra in Slay the Spire 2. More than enough for 144Hz. You can comfortably play at 1440p.
At 1440p it gets 327 FPS and at 4K 253 FPS at Ultra quality.
This GPU is more than enough — you can play at 1440p or 4K comfortably
