Quick Answer
At 1440p, an RTX 5090 runs Lost Ark above 120fps at Max settings with ample headroom, easily feeding a 1440p 144Hz panel. At roughly R55,000-R65,000 at Evetech, the 5090 is more card than 1440p Lost Ark needs, where a mid-range GPU already holds 90fps-plus in busy hubs.
RTX 5090 at 1440p in Lost Ark
Lost Ark's isometric engine keeps GPU demand modest even at 1440p, so a 5090 stays lightly loaded while delivering 120fps-plus in raids and open zones. The card holds above 90fps in 200-player city hubs, where the limiter is CPU and engine threading rather than the GPU. With so much spare capacity, the 5090 runs cool and quiet, which matters during long SA raid sessions in summer. 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.
A Balanced 1440p Lost Ark Build
For 1440p Lost Ark alone, an RTX 5060 Ti or RTX 5070 (around R10,000-R17,000) already clears 90fps, so a 5090 is for those who also game at 4K. Pair whichever GPU you choose with a Ryzen 5 9600X and 16GB-32GB DDR5-6000 to keep crowded hubs smooth. Cap frame rate to your panel refresh to keep temperatures and noise down through marathon raid nights.
FAQ
What FPS does an RTX 5090 get in Lost Ark at 1440p?
Above 120fps at Max in open zones and over 90fps in 200-player hubs. It comfortably saturates a 1440p 144Hz panel.
Is an RTX 5090 overkill for 1440p Lost Ark?
For Lost Ark alone, yes. An RTX 5070 already clears 90fps at 1440p Max. The 5090 is for buyers who also game at 4K.
What limits Lost Ark FPS in busy hubs?
CPU and engine threading, not the GPU. A Ryzen 5 9600X with fast DDR5-6000 keeps frame times stable in crowded 200-player cities.
Lost Ark, an Evetech RTX 5070 with a Ryzen 5 9600X already clears 90fps in busy hubs. Choose the 5090 only if you also game at 4K.
