Besiege PC Hardware Guide
Official requirements explained
The official minimum for Besiege is a 2.2GHz dual-core CPU, a graphics card with 1GB of dedicated VRAM, 4GB of RAM and 3GB of storage. The recommended level asks for a 4GHz quad-core CPU, 3GB of dedicated VRAM, 8GB of RAM and 5GB of storage. By today's standards the minimum CPU is roughly equivalent to an AMD Athlon 64 X2 6000+, which is very old entry-level hardware, and the recommended CPU is close to an Intel Core i3-3220, also a very old entry-level part. The publisher did not list a specific GPU model, so the graphics requirement can only be read from the VRAM amount, and we have no GPU tier reference for it.
The gap between the two levels is modest, mainly in CPU core count and VRAM. That means almost any reasonably recent PC clears the recommended tier comfortably. The one figure worth treating as a floor rather than a target is memory: 8GB is the recommended minimum, but 16GB is now the common baseline and leaves more room if you run other programs or record footage.
No SSD is required. A hard drive will run the game, but level loading and save/load operations will be slower than on solid-state storage.
Recommended builds for three budgets
The entry build pairs an AMD Radeon RX 5600 XT or NVIDIA GeForce RTX 2060 6GB with an AMD Ryzen 3 3100 or Intel Core i3-10100F and 16GB of RAM. It sits well above the official recommended tier and suits players on a tight budget who are happy with medium settings.
The mainstream build uses an NVIDIA GeForce RTX 3060 Ti or AMD Radeon RX 6700 XT with an AMD Ryzen 5 3600 or Intel Core i5-10400 and 16GB of RAM. This is the sweet spot for most players, running at high settings with headroom for mods or background software.
The high-end build combines an NVIDIA GeForce RTX 4070 Ti or AMD Radeon RX 7900 GRE with an AMD Ryzen 5 5600X or Intel Core i5-12400 and 32GB of RAM. This is well beyond what the game needs, and is better suited to people running high-resolution displays or streaming and recording at the same time.
Graphics settings with the biggest impact
Besiege is built around physics simulation, so its cost comes mostly from large numbers of parts and physics calculations rather than heavy materials or lighting. Among the graphics options, shadows, volumetric effects and view distance are usually the most expensive, so lower those first. If the game offers settings that affect the number of objects or simulation detail, those matter too, because more parts on screen means more work for the processor.
Anti-aliasing and post-processing can be traded off depending on your display resolution. At higher resolutions anti-aliasing matters less, so it is reasonable to reduce it for smoother performance. If your graphics card supports it, upscaling technologies such as DLSS, FSR or XeSS can help: they render the scene at a lower internal resolution and reconstruct it at your target resolution, which usually costs little visible quality. Check the in-game menu to see which options are actually available.
A practical approach is to start at medium settings, confirm the game runs smoothly, and then raise shadows and view distance until you reach a balance you are happy with.
Laptops and handheld PCs
Laptop graphics cards often share names with desktop parts, such as an RTX 4070, but the laptop versions run at lower power limits and are constrained by cooling, so they perform noticeably below their desktop namesakes. When evaluating a laptop, look at its actual power and cooling design rather than the model name alone. Under long sessions, poor cooling can cause throttling and uneven performance.
Handheld PCs such as the Steam Deck or ROG Ally are generally designed around low power use and suit lighter games. We do not have Steam Deck verification data for this title, so the advice here is general: start from the built-in low presets and keep the device plugged in or well charged so it does not drop into a power-saving mode that reduces performance.
Storage and memory
For memory, the official minimum is 4GB and the recommended level is 8GB, but the operating system itself uses a fair share, so 16GB is the more comfortable choice. Dual-channel configuration, meaning two matching modules in the correct slots, generally gives better bandwidth than a single stick and helps overall smoothness.
For storage, the official minimum is 3GB and the recommended figure is 5GB. Those numbers are for the game itself, so leave extra room for updates and save files. No SSD is required, but if you can use one, it noticeably shortens loading times. A hard drive with enough free space will still run the game properly.
