Can I Run Hot Tub Simulator?
Released in 2021, Hot Tub Simulator is a casual simulation game built by Mitsuki Game Studio. It offers a single player campaign. It carries 36 achievements. Progress follows the account through Steam Cloud rather than sitting on one disk. With only 113 reviews on Steam, there is little community data on how it behaves across hardware. The game ships for Windows alone. At 5 years old it targets an older hardware baseline than most buyers now own.

Setting and environment
Players spend their time in an anime styled world, moving through an open sandbox. Play is presented in three dimensions. There are 8 official screenshots to judge the look from. That openness is what costs performance. Hot Tub Simulator has no loading walls to hide behind, so terrain and detail keep flowing in as the player moves.
Why Hot Tub Simulator is demanding
The ask Hot Tub Simulator makes is moderate. GTX 1060 lands near our RTX 3060 reference, so a typical gaming PC is the right yardstick. Hot Tub Simulator takes about 4 GB of disk space. Its 16 GB RAM requirement matches what a typical machine already has. Minimum and recommended sit far apart here, which usually means Hot Tub Simulator scales hard with the hardware you give it.
This reading comes from the published requirements and our own benchmark tables, not from the store listing.
Can you run Hot Tub Simulator?
Hot Tub Simulator is light on hardware. Its minimum, NVIDIA GeForce GTX 780 or similar, 8 GB RAM, about 4 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 | Comfortable | 1.7x |
| 1440p | Borderline | 0.96x |
| 4K | Below the bar | 0.43x |
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.
