Horizon Forbidden West PC port analysis: Another game that can exceed 8GB VRAM use

Horizon Forbidden West screenshots.

Horizon Forbidden West launched on PC on March 21, 2024 — over two years after the game initially came out on the PlayStation 5 and PlayStation 4. That’s quite the wait, but the original Horizon Zero Dawn was well-received and PC gamers have been waiting for their preferred release. Nvidia provided us with a code for testing the game, as this is an Nvidia-promoted title, but don’t worry: We’ve tested it on the best graphics cards and it doesn’t seem to outright favor Team Green’s hardware, other than the inclusion of DLSS 3 frame generation but not AMD’s FSR 3 alternative.

As a PC port, Horizon Forbidden West was initially created for and optimized to run on AMD hardware — the PlayStation 5 has a Zen 2 8-core CPU and 36 RDNA 2 compute units, while the PS4 version had to make do with far less capable hardware. The PlayStation 5 has 16GB of shared GDDR6 memory with 448 GB/s of bandwidth. Unlike the Xbox Series X, the PS5 memory isn’t partitioned into CPU and GPU segments, which means games can easily utilize up to the full 16GB for textures and other data, though in practice most seem to top out at around 12GB of memory use. That will prove to be an important consideration in terms of what settings and resolutions you can comfortably run on PC hardware.
