Can you run Flux Caves?
Flux Caves targets a mainstream modern PC: Radeon R9 280X 3GB and 8 GB of RAM for the minimum, stepping up to Radeon RX 580 8GB for the recommended experience. No single part dominates the requirements, so a balanced mid-range build clears it.
Bottleneck: GPU
Projected by resolution
| Resolution | Projection | Headroom |
|---|---|---|
| 1080p | Comfortable | 1.89x |
| 1440p | Borderline | 1.06x |
| 4K | Below the bar | 0.47x |
A projection, not a measurement. We scale the published GPU requirement by pixel count, since 1440p draws 1.78 times the pixels of 1080p and 4K draws 4 times as many, then compare against RTX 3060 / Ryzen 5 build. The publisher did not state a target resolution, so 1080p is assumed as the baseline. We hold no frame rate data, so no FPS figure is claimed. Headroom above 1 means the reference machine has room to spare at that resolution.
