Can I Run Bus Simulator 21?
stillalive studios released Bus Simulator 21 in 2021. It is a simulation game, published by astragon Entertainment. It offers a single player campaign and cooperative play. Saves sync through Steam Cloud, so moving between machines does not cost progress. Completionists have 37 achievements to work through. Its Steam review count passes 3 thousand, a large enough sample that odd hardware behaviour would be known by now. Steam lists support for 14 languages. Full controller support is present, so nothing needs configuring before a pad works. Being 5 years old, it was built for the hardware of its day, so a current machine usually has headroom over the published figures. The game ships for Windows alone.

Setting and environment
Bus Simulator 21 structures its play around dense spaces with several routes through each problem. It is played in three dimensions. The publisher supplies 10 storefront screenshots of these environments.
Why Bus Simulator 21 is demanding
Bus Simulator 21 sits in the middle of the demand range, targeting NVIDIA GeForce GTX 1070 (, a tier a mainstream card from the last few generations reaches without difficulty. Minimum and recommended sit far apart here, which usually means Bus Simulator 21 scales hard with the hardware you give it. DirectX 12 is named, so Bus Simulator 21 expects a graphics driver and card from the modern era rather than merely a fast one. Bus Simulator 21 needs 64 bit Windows. Bus Simulator 21 needs only 8 GB of RAM. The install is small at roughly 18 GB. The 8 GB VRAM figure quietly excludes a lot of 6 GB hardware that would otherwise cope.
This reading comes from the published requirements and our own benchmark tables, not from the store listing.
Can you run Bus Simulator 21?
Bus Simulator 21 is light on hardware. Its minimum, NVIDIA GeForce GTX 760 (2GB VRAM) / AMD Radeon R9 280 (2GB VRAM) or higher, 8 GB RAM, about 18 GB free, sits below what an entry-level PC ships with today, so nearly any modern machine, and many older ones, will run it.
Bottleneck: GPU
Projected by resolution
| Resolution | Projection | Headroom |
|---|---|---|
| 1080p | Runs well | 1.36x |
| 1440p | Below the bar | 0.77x |
| 4K | Below the bar | 0.34x |
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.
Common GPUs
| Graphics card | Verdict |
|---|---|
| GTX 1060 6 GB | Runs well |
| GTX 1060 Laptop | Playable |
| GTX 1650 4 GB | Playable |
| GTX 1650 Laptop | Playable |
| RTX 2060 6 GB | Runs well |
| RTX 2060 Laptop | Runs well |
| RTX 3060 12 GB | Runs great |
| RTX 3060 Laptop | Runs great |
| RTX 4060 8 GB | Runs great |
| RTX 4060 Laptop | Runs great |
| RTX 3070 8 GB | Runs great |
| RTX 3070 Laptop | Runs great |
| RTX 4070 12 GB | Runs great |
| RTX 4070 Laptop | Runs great |
| RX 6600 8 GB | Runs great |
Each card is compared against Bus Simulator 21's published GPU requirement, assuming an otherwise-capable PC. Laptop rows use the real mobile chip's benchmark, a mobile GPU is always slower than its desktop namesake.
