Quick Answer

A Arc B580 hits 120fps in Stellar Blade at 4K once you lean on upscaling and trim a couple of heavy effects. Set the upscaler to Quality at 4K, keep textures high, and drop shadows and volumetrics one notch to lock the 120fps target.

The 120fps Recipe At 4K

To hold 120fps at 4K on a Arc B580, start with Performance or Balanced upscaling (DLSS or FSR depending on the card) and the preset at High rather than the top tier. The biggest framerate wins in Stellar Blade come from shadow quality, volumetric fog and screen-space reflections, so set those to Medium-High first. Texture quality can stay maxed because the Arc B580 has the VRAM for it at 4K, and that is where most of the visual sharpness lives anyway.

Where To Spend And Where To Save

Keep ambient occlusion, anisotropic filtering at 16x, and texture detail high; they barely cost frames but carry the image. Pull post-processing effects like motion blur and chromatic aberration to taste, and cap the framerate slightly above 120fps so frame pacing stays smooth on a matching high-refresh panel. A Arc B580 (around R6,200 at Evetech) has the grunt for this once the heaviest effects are dialled in.

Pairing The Arc B580 For SA Buyers

For a clean 120fps experience at 4K, pair the Arc B580 with a CPU that will not bottleneck it (a current Ryzen 5 or Core i5 class chip) and a monitor whose refresh rate matches your 120fps target. Most SA gamers chasing 120fps will want a 4K 144Hz panel so the extra frames are visible rather than wasted.

FAQ

Can a Arc B580 run Stellar Blade at 120fps at 4K?

Yes. With Performance or Balanced upscaling and shadows and volumetrics set to Medium-High, a Arc B580 sustains 120fps at 4K in Stellar Blade. Native max settings will fall short of that target.

Which settings should I lower first in Stellar Blade?

Drop shadow quality, volumetric fog and screen-space reflections first. They are the heaviest effects and cutting them one notch recovers the most frames with little visible loss.

Is upscaling worth using in Stellar Blade?

Absolutely. DLSS or FSR Quality mode is the single biggest lever for hitting 120fps at 4K on a Arc B580, and at 4K the image stays sharp.

TIP

Blade set the upscaler to Performance or Balanced and shadows to Medium-High first to lock 120fps on a Arc B580.
