Can I Run Cosmic Star Heroine?
Zeboyd Digital Entertainment LLC released Cosmic Star Heroine in 2017. It is an indie role playing game, self published by the studio. It offers a single player campaign. Critics scored it 77 on Metacritic. It carries 814 Steam reviews, a small sample, so first hand performance reports are thin. Progress follows the account through Steam Cloud rather than sitting on one disk. It carries 33 achievements. It is a Windows title, so the requirements below are the Windows ones. Being 9 years old, it was built for the hardware of its day, so a current machine usually has headroom over the published figures. A gamepad works without remapping, since controller support is complete.

Setting and environment
Cosmic Star Heroine places its action in a science fiction setting, and the player works through spaces built for exploration. The publisher supplies 21 storefront screenshots of these environments. Continuous worlds put sustained pressure on memory and storage, and Cosmic Star Heroine can never assume the player will stop and let it load. Play is presented in two dimensions.
Why Cosmic Star Heroine is demanding
The graphics requirement for Cosmic Star Heroine is light. Hardware around 2GB of VRAM: GTX 750ti, Radeon HD 7850 is enough, so Cosmic Star Heroine runs on machines never bought for gaming. At 4 GB, system memory is undemanding. Disk footprint is light, near 6 GB.
This reading comes from the published requirements and our own benchmark tables, not from the store listing.
Can you run Cosmic Star Heroine?
Cosmic Star Heroine targets a mainstream modern PC: Intel HD 405 Graphics 600 MHz and 2 GB of RAM for the minimum, stepping up to 2GB of VRAM: GTX 750ti, Radeon HD 7850 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 | 5.31x |
| 1440p | Comfortable | 2.99x |
| 4K | Runs well | 1.33x |
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.
