In order to run Homeworld 3, you'll need at least an Intel Core i5-8600K or Ryzen 5 3600X CPU, 12GB of RAM, and either an Nvidia Geforce GTX 1060, AMD Radeon R9 480, or Intel Arc A380 graphics card. This will get you low graphics preset and 1080p resolution. In order to run it at 4K resolution with Ultra settings, you'll need some serious hardware, including Intel Core i7-13700K or Ryzen 9 7900X, 16GB of RAM, and either an Nvidia RTX 3080 or AMD RX 6900XT graphics card.

The previous hardware does not include any RT settings, so if you want to run 1080p with low RT settings, you'll need RTX 4060 or RX 6650 XT graphics cards, and for 4K wiht Epic Ray Tracing settings, requirements go up to RTX 4080 or RX 7900 XTX.

As announced by the publisher and the developer, Homeworld 3 will support the latest graphics technology, including:
HDR & Ray Tracing: HDR and Ray Tracing, for soft shadows with contact hardening, can be enabled on compatible graphics cards.
AMD: AMD FidelityFX Super Resolution 2 will be supported for compatible AMD, NVIDIA and Intel graphics cards.
NVIDIA: NVIDIA DLSS 3 and Frame Generation will be supported for compatible NVIDIA graphics cards.
Intel: Compatible with Intel ARC series of graphics cards.

Homeworld 3 is currently scheduled to launch in February 2024, and in the meantime, you can enjoy the gameplay trailer released earlier.
