Quick Answer

At 1080p, an RTX 5090 runs Final Fantasy XIV Online above 200fps at Max settings, far past most 1080p panels' refresh. The 5090 (around R55,000-R65,000 at Evetech) is heavily underused in FFXIV at 1080p, where even a mid-range card holds well over 144fps in busy hubs.

RTX 5090 at 1080p in FFXIV

FFXIV is a well-optimised MMO that leans more on the CPU than the GPU. At 1080p Max, a 5090 pushes past 200fps in open zones and stays above 144fps in crowded hubs like Limsa Lominsa, where many player characters tax the CPU. Because the card is barely loaded at 1080p, it runs cool and quiet, and your real ceiling becomes CPU single-thread speed in the busiest content. In practice that means the card spends most of its time well below its 575W power ceiling, so fan noise stays low even in a warm SA room. For a balanced build, a 1TB NVMe SSD also trims load times noticeably, which matters more day to day than a few extra frames here.

The Right 1080p FFXIV Build

For 1080p FFXIV alone, a 5090 is overkill: an RTX 5070 near R14,000-R17,000 already exceeds 144fps. What truly helps in raids and packed hubs is a strong CPU. Pair any capable GPU with a Ryzen 7 9800X3D and 32GB DDR5-6000 to keep frame rates high where crowds spike CPU load. Save the 5090 for a future 4K high-refresh setup where its power is actually used.

FAQ

What FPS does an RTX 5090 get in FFXIV at 1080p?

Over 200fps in open zones at Max settings and above 144fps in crowded hubs. The card is heavily underused at this resolution.

Is FFXIV CPU or GPU heavy?

Mostly CPU, especially in crowded hubs and raids. A fast chip like the Ryzen 7 9800X3D lifts frame rates more than a bigger GPU at 1080p.

Do I need a 5090 for 1080p FFXIV?

No. An RTX 5070 already exceeds 144fps at 1080p Max. The 5090 is only worth it for a future 4K high-refresh build.

TIP

at 1080p, a fast CPU matters most in crowded hubs. Pair any capable Evetech GPU with a Ryzen 7 9800X3D; the 5090 only pays off at 4K.
