Barotrauma PC Hardware Guide
Official requirements explained
Barotrauma lists a minimum of a dual-core 2.4 GHz CPU, 4 GB of RAM, and a graphics card with 2 GB of memory (dedicated VRAM or shared RAM) that supports Shader Model 2.0 or later. In today's terms, the minimum CPU roughly corresponds to very old entry-level parts like the Athlon 64 X2 6000+, and the minimum GPU is around the GT 1030 class of integrated or entry graphics. The bar is very low, so almost any PC that still boots can attempt to run the game.
The recommended level steps up to a quad-core 3.0 GHz CPU, 8 GB of RAM, and a GeForce GTX 950 or Radeon R9 370 class graphics card with at least 2 GB of VRAM. In our reference, the CPU sits around the Core i3-3220 class and the GPU is close to a GTX 670. The gap between minimum and recommended mostly means smoother play when many ships, objects, and players are on screen at once, rather than extra features. Meeting the recommended tier means you are running at the level the publisher suggests for everyday play.
The official storage requirement is 2 GB, and no SSD is required. A mechanical hard drive will run the game, but level loading and save reads will take noticeably longer.
Note that the publisher's listed requirements are the reference point here. We do not have measured performance data for this game.
Recommended builds for three budgets
The entry build suits players who want to play occasionally with friends and do not need high visual settings. A GTX 1650 4GB class card paired with a quad-core CPU such as the Ryzen 3 3100 or Core i3-10100F, plus 16 GB of RAM, sits well above the recommended tier and covers most of the game's scenes comfortably.
The mainstream build is the best value for most players who want long sessions and also use the PC for other things. A GTX 1660 Super or RTX 3050 8GB class card with a Ryzen 5 3600 or Core i5-10400, and 16 GB of RAM, leaves a comfortable margin above the recommended tier, which helps multiplayer ship scenes and effects stay steady.
The high build is for players who want to push visuals further or use a high-resolution display. Options such as an RTX 2080 Super, RTX 4060, or Radeon RX 7600 paired with a Ryzen 5 5600X or Core i5-12400, plus 16 GB of RAM, is more than this game needs. Its main benefit is headroom for other games and future use.
The builds are estimates based on official requirements and published specifications, not measured results.
Graphics settings with the biggest impact
Barotrauma is a 2D simulation, so its rendering load comes mostly from water and fluid effects, lighting, and many simultaneous objects rather than complex 3D geometry. Shadows and lighting quality, particle density, and simulation-related detail are usually the most expensive options. If your PC is on the weaker side, lowering these first gives the clearest benefit to smoothness.
Resolution and anti-aliasing also add load, but in a 2D art style, reducing anti-aliasing usually costs little visually. Keep text and interface sharp, and avoid turning off warning lights and alarm-related visuals, since gameplay depends on reading danger cues quickly.
Upscaling technologies such as DLSS, FSR, and XeSS render at a lower resolution and let an algorithm scale the image up. They matter less for a 2D game than for a demanding 3D title, but if your graphics card supports one and you want headroom, it is worth trying. Ray tracing is not a focus in this game and is generally not needed.
Laptops and handheld PCs
Laptop graphics chips often carry the same name as desktop parts but deliver less performance, because they run under lower power limits and more conservative cooling. Given the official recommended requirements, most recent laptop dedicated GPUs should reach the recommended tier, but set the power mode to high performance and make sure cooling works properly, since thermal throttling can cause stutter.
Handheld PCs such as the Steam Deck or ROG Ally generally use integrated or low-power graphics. For a 2D simulation like this, they are usually capable, but adjust settings in general ways: lower the resolution, disable unnecessary effects, and keep an eye on battery life and temperature. FrameScope has no verified test data for these devices, so this is general guidance only.
Storage and memory
Aim for at least 8 GB of RAM, and 16 GB is more comfortable, installed in dual-channel configuration so the CPU and graphics hardware exchange data efficiently. The official minimum is 4 GB, but with a browser, chat app, or other background programs open, 4 GB will feel tight.
The official storage requirement is 2 GB, but leave more room than that for updates and saves. An SSD is not an official requirement, but it noticeably shortens level loading and save reads. On a tight budget, a hard drive will still run the game, just with longer waits.
