These picks target a smooth experience at each resolution. For native 4K at max settings — especially with ray tracing or path tracing — aim higher than the high-end pick and use DLSS/FSR upscaling, which can effectively move a card up a tier.

Frequently Asked Questions
What GPU do I need for Zen Aquarium?
For smooth 1080p, a AMD Radeon R9 390X-class card meets the recommended bar. For 1440p, step up to around a NVIDIA GeForce RTX 3050 6GB. For 4K, a NVIDIA GeForce RTX 5050 or better gives the most headroom. You can verify any card with our free Can I Run It checker.
Can I run Zen Aquarium on a cheaper GPU?
Often yes, at lower settings or with upscaling (DLSS/FSR). Anything at or above the game's minimum GPU will launch it; the picks above target a smooth, recommended-level experience.
Do I need a new CPU too?
For most games the GPU matters most, but a badly paired CPU can bottleneck a strong card. Check the balance with our bottleneck calculator before buying.
