Official Terraria system requirements, player reports on Terraria performance, and a check against your GPU and CPU.
Published on the Steam store page by the developer. This is that text, not a benchmark.
Most reviews indicate that Terraria runs smoothly on low settings and is optimized for a variety of hardware, with minor loading times and some performance issues when effects are turned on.
Drawn from 8 reviews that mention performance.
Pick a GPU and a CPU. The result compares their class with the parts named in the official requirements. It is not an FPS estimate.
