Unplayable Fortnite Performance on Intel Arc B580 (Ryzen 7600X)

[Ralpis]

I’m posting this here because at this point I’m convinced this is either an Intel Arc driver issue or a serious Fortnite compatibility problem.

I get FPS drops and constant stuttering ONLY in Fortnite.
Every other game runs completely fine (including heavy AAA titles), stable frametimes, normal GPU usage, no issues at all. Fortnite is the only game that behaves like this.

System specs:

• GPU: Intel Arc B580

• CPU: Ryzen 5 7600X

• RAM: 32 GB DDR5

• Storage: NVMe SSD

• OS: Windows 11

• Re-BAR: Enabled

• BIOS: Fully updated B650 prime wifi II ver.3602

• Drivers: Latest Intel Arc GPU drivers + latest AMD chipset drivers

What I already tried 

• Windows reinstall

• DX11, DX12 and Performance Mode

• Low → Epic settings

• FPS capped / uncapped

• V-Sync on/off

• Background apps disabled

• Power plans checked

Symptoms:

• Random FPS drops and microstutters

• Inconsistent frametimes

• GPU usage stays low

• CPU is not bottlenecked

• Happens regardless of graphics settings

This makes zero sense from a hardware perspective. A 7600X + 32 GB RAM should not struggle with Fortnite at all, yet the game feels worse than on much weaker systems.

At this point I honestly don’t know if:

• Fortnite is poorly optimized for Intel Arc

• Arc drivers still have major issues with Unreal Engine / Fortnite specifically

• Or there’s some deeper scheduling or compatibility problem

What frustrates me the most is that the GPU works great everywhere else, but Fortnite 

So I’m asking directly:

• Is this a known Intel Arc + Fortnite issue?

• Is there an actual workaround or driver fix coming?

• Or should people who play Fortnite just avoid Intel Arc GPUs altogether?

Because right now, I honestly cannot recommend this GPU to anyone who plays Fortnite, which is ridiculous given the specs and price.

Any official response or real solution would be appreciated, because I’m completely out of ideas.
