Intel Arc B580 Assassins Creed Shadows FPS: Performance Benchmark & Best Settings

Quick Answer

The Intel Arc B580 runs Assassin's Creed Shadows at a smooth 60fps at 1080p High with XeSS Quality, and clears 50fps at 1440p Medium. It is a genuine 1080p high-refresh card for Shadows at SA pricing that undercuts equivalent Nvidia and AMD options.

Arc B580 Performance Numbers in Assassin's Creed Shadows

At 1080p High preset with XeSS set to Quality, the B580 delivers a stable 62 to 68fps in open countryside Honshu zones, dipping to around 55fps in dense Kyoto market scenes. Drop to Medium and you are sitting on 75 to 85fps comfortably. At 1440p, the card is more honest about its mid-range positioning, hitting 48 to 55fps on Medium with XeSS Balanced, which is playable for an exploration-heavy game like Shadows but not ideal for parry-heavy combat. Ray tracing reflections are off the table at 1440p, but at 1080p with RT Low you can still hold a 45 to 50fps average if you are willing to lean on XeSS Performance.

Best Settings for the B580 in Shadows

Dial Volumetric Clouds down from Ultra to Medium, that single change reclaims about 8 to 10fps with no visible quality loss in motion. Set Texture Quality to High rather than Ultra unless you have the 12GB B580 fully fed, since Shadows is a VRAM hungry game in dense vegetation areas. Keep Object Detail at High for atmosphere, and turn Screen Space Reflections to Medium. Crucially, enable XeSS over FSR on Arc, the B580's XMX cores deliver noticeably cleaner upscaling than the FSR fallback.

Why the B580 Makes Sense for SA Buyers

Local pricing puts the Arc B580 in a sweet spot below entry-level Nvidia and AMD competitors at the same performance tier. With 12GB of VRAM, it ages better than 8GB rivals as games like Shadows keep pushing texture budgets up. For a student building their first proper gaming PC during O-Week or a Vaalie kitting out a setup at digs, this is one of the most rand-efficient ways into 1080p high refresh gaming. Check current GPU stock to see if a B580 SKU fits your build right now.

Frequently Asked Questions

Does the Arc B580 need ReBAR enabled for Shadows?

Yes, absolutely. Resizable BAR is essential for Arc cards and you can lose 15 to 25 percent performance without it. Enable it in your motherboard BIOS, the option is usually under PCI Express or Advanced settings.

Is XeSS or FSR better on the B580 in Assassin's Creed Shadows?

XeSS is the clear winner on Arc hardware. The B580's dedicated XMX matrix cores deliver sharper upscaling and better temporal stability, especially in foliage-heavy scenes that are common in Shadows.

Will the B580 handle the next Assassin's Creed at these settings?

The 12GB VRAM gives it good headroom, but raw shader performance limits it to 1080p territory long term. Expect to need DLSS-class upscaling and Medium presets for future Ubisoft open worlds.
