Planet Zoo PC Hardware Guide
Official requirements explained
The publisher's minimum requirements list an Intel i5-2500 or AMD FX-6350 class CPU, an NVIDIA GeForce GTX 770 (2GB) or AMD Radeon R9 270X (2GB) graphics card, 8GB of RAM and 16GB of storage. Today, an i5-2500 is roughly in the same old-generation entry band as the i5-2400, while the GTX 770 and R9 270X sit between the GTX 670 and the RX 580 in the older entry tier.
The recommended requirements step up to an Intel i7-4770K or AMD Ryzen 5 1600 class processor, an NVIDIA GeForce GTX 1070 (8GB) or AMD Radeon RX 580 (8GB), 16GB of RAM and the same 16GB of storage. The i7-4770K and RX 580 8GB both fall into the older entry band in our tier ranking, so the recommended tier is a baseline for running the game at moderate settings rather than a high-end bar. The main differences between minimum and recommended are RAM (8GB versus 16GB) and graphics memory capacity, so if you want to keep more detail in a large zoo, start from the recommended figures.
The publisher does not list an SSD as required, so this guide does not treat it as a hard requirement. Much of the simulation work in this game lands on the processor, so core count and per-core performance matter a lot in the late game. Do not focus only on the graphics card.
Recommended builds for three budgets
The entry build suits players who want a low-cost way in and are happy to lower their settings. The graphics options here are the Radeon RX 6500 XT, Intel Arc A380, GTX 1650 or RTX 3050 6GB. These only meet the minimum requirement, so expect to turn settings down noticeably. For the processor, the Ryzen 3 3100 meets the recommended tier, while the Core i3-10100F is comfortably above it. Use 16GB of RAM, which is the minimum for this build.
The mainstream build is for most players who want a comfortable 1080p experience. The RTX 3050 8GB meets the recommended tier, and cards such as the Arc A580, RX 5700, RTX 2060 12GB, RTX 3060 8GB and RX 6600 are well above it. Processors such as the Ryzen 5 3600 and Core i5-10400 are also well above the recommended tier. This is the best value tier, and 16GB of RAM remains the standard.
The high-end build suits players who want higher settings or resolutions and some headroom for the next few years. Graphics choices include the RTX 3060 Ti, RX 6700 XT, RTX 3070 and RTX 4060 Ti 8GB, and processors such as the Ryzen 7 5700X and Core i7-11700K are well above the official recommended tier. Move to 32GB of RAM here so multitasking and mods run more smoothly.
Graphics settings with the biggest impact
In a management sim like this, the most demanding options are usually the ones tied to unit counts and simulation rather than texture resolution. Crowd density, the number of animals and guests, physics detail and the far draw distance all add load on the processor. If a large park starts to stutter, lower these first, since that usually helps more than dropping texture quality.
On the graphics card side, shadow quality, volumetric lighting and ambient occlusion are often expensive. Shadows are very visible in a park full of buildings and foliage, so try dropping them from the highest preset to medium and see whether the difference bothers you. Volumetric lighting and some global illumination effects add atmosphere but are not needed for gameplay, so they are the first things to switch off when things get tight. If the game offers ray tracing, it is generally not worth enabling on cards at this level if you want steady frame pacing.
Upscaling technologies such as DLSS, FSR and XeSS render at a lower internal resolution and scale the image up, which can ease the load on the graphics card with modest image quality loss. They mainly help the GPU, though, so if the processor is the bottleneck the gain will be limited. Anti-aliasing is a matter of taste; medium settings are usually enough.
Laptops and handheld PCs
Laptop graphics chips often share a name with desktop cards, such as an RTX 3060 laptop and an RTX 3060 desktop, but their power limits and cooling differ a lot, so real performance is usually lower. When buying a laptop, check the power range (TGP) and the cooling design of that model rather than relying on the model name. Long sessions in a sim can stress thermals, so keep vents clear, consider a cooling pad and use a performance power profile while playing.
Handheld PCs such as the Steam Deck and ROG Ally can generally run games like this, but we have no Steam Deck verification data, so we cannot give a compatibility rating for that platform. Handhelds have tight power budgets, so lower the settings, cap the frame rate to preserve battery and stability, and use the built-in upscaling where available. Because late-game parks are large, reducing the unit-count related settings will help more than adjusting textures if you see stutters.
Storage and memory
The recommended 16GB of RAM is already the baseline for a large park simulation. If you run a browser, streaming software or mod tools alongside the game, 8GB will feel tight, so aim for 16GB even on the entry build. If your budget allows, 32GB gives multitasking more room and reduces slowdowns caused by running out of memory late in a save. Install RAM in dual-channel configuration so the processor has more bandwidth to work with, which helps a lot in a game that relies on heavy computation.
The publisher lists 16GB of storage, but when installing leave extra room for updates, saves and mods. The publisher does not require an SSD, though an SSD noticeably shortens load times and makes saves and map transitions faster. A hard drive will still run the game, just with longer waits. Keep enough free space on the drive so that a nearly full disk does not affect system stability or updates.
