Quick Answer
At 1080p, an RTX 5090 runs Lost Ark above 120fps at Max settings, comfortably past the panel needs of this isometric ARPG. The 5090 (around R55,000-R65,000 at Evetech) is heavily overkill for 1080p Lost Ark, where a mid-range card already holds well over 100fps even in busy raid lobbies.
RTX 5090 at 1080p in Lost Ark
Lost Ark's top-down view keeps GPU load modest, and a 5090 at 1080p Max sits at low utilisation while pushing past 120fps in raids and bustling cities. The real strain in 200-player city hubs is CPU and the game's own engine, not the graphics card, so the 5090's power goes largely unused. The benefit at 1080p is simply a card that runs cool, quiet and never dips. 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.
Building Smart for 1080p Lost Ark
For 1080p Lost Ark alone, a 5090 is unnecessary: an RTX 5060 Ti near R10,000-R13,000 already clears 100fps. Spend instead on a fast CPU and RAM, since busy hubs stress those most. A Ryzen 5 9600X with 16GB DDR5-6000 keeps frame times stable in crowded zones, and a 144Hz panel lets the high frame rate show. Reserve a 5090 for a 4K build where its power is genuinely needed.
FAQ
What FPS does an RTX 5090 get in Lost Ark at 1080p?
Over 120fps at Max settings, even in busy raid lobbies. The card sits at low utilisation, so it stays cool and quiet.
Is Lost Ark GPU heavy?
Not particularly. Its isometric view keeps GPU load light. Crowded city hubs stress the CPU and engine more than the graphics card.
Do I need a 5090 for 1080p Lost Ark?
No. An RTX 5060 Ti already exceeds 100fps at 1080p Max. Spend on a fast CPU instead, and save the 5090 for a 4K build.
Lost Ark, busy hubs stress the CPU more than the GPU. An Evetech RTX 5060 Ti with a Ryzen 5 9600X already clears 100fps; save the 5090 for 4K.
