The RTX 5090 is the fastest consumer GPU available, so the real question for Red Dead Redemption 2 is not whether it runs, but how far past your monitor's refresh rate it goes at 1080p.

Quick Answer

The RTX 5090 runs Red Dead Redemption 2 at 1080p maxed at around 180-220 fps, largely CPU-limited. At 1080p the card is underused; RDR2 is where it stretches its legs at 4K with ray-traced-quality settings.

Why 1080p Underuses The Card

RDR2 is demanding, but at 1080p the RTX 5090 renders frames faster than most CPUs can feed it, landing around 180-220 fps maxed with a strong chip like the Ryzen 7 9800X3D. The 1% lows depend on the CPU here, so 1080p does not show the GPU's real strength.

DLSS And Settings

At 1080p, max every setting; the RTX 5090 has the headroom. DLSS is unnecessary at this resolution since you are CPU-bound, though DLAA improves image quality at no frame-rate cost. For the best use of this card in RDR2, move to 4K, where it holds 110-140 fps maxed.

RTX 5090 In SA

The RTX 5090 is currently stocked at Evetech in the R55,000-R65,000 band depending on model. For RDR2 at 1080p it is overkill; it is built for 4K maxed play. Pair it with a Ryzen 7 9800X3D to push the CPU-limited 1080p frame rate as high as possible.

FAQ

What FPS does the RTX 5090 get in RDR2 at 1080p?

Around 180-220 fps maxed, largely CPU-limited. The GPU renders faster than the CPU can feed it at this resolution.

Should I use DLSS in RDR2 at 1080p on a 5090?

No need; you are CPU-bound. Use DLAA instead for sharper image quality at no frame-rate cost, since you have frames to spare.

Is the RTX 5090 worth it for RDR2 at 1080p?

Only if you also play at 4K or run the most demanding current titles. At 1080p, a far cheaper GPU would already saturate most monitors.

TIP

in RDR2 you have frames to spare, so enable DLAA for a sharper image at no fps cost, or move to 4K to use the RTX 5090 properly.
