The RTX 5090 is the fastest consumer GPU available, so the real question for The Witcher 3 is not whether it runs, but how far past your monitor's refresh rate it goes at 1440p.

Quick Answer

The RTX 5090 runs The Witcher 3 (next-gen update) at 1440p Ultra with full ray tracing at around 140-180 fps, and well past 200 fps with ray tracing off. At 1440p the card has huge headroom, so a high-refresh panel is the right pairing.

1440p Performance

With the next-gen update's ray tracing maxed, the RTX 5090 holds The Witcher 3 at 1440p around 140-180 fps. Disable ray tracing and it clears 200-plus fps. The card is barely stressed at 1440p, so frame rates comfortably saturate a 165Hz or 240Hz monitor.

DLSS And Ray Tracing

At 1440p the RTX 5090 does not need DLSS to hit high frame rates, but enabling DLSS Quality plus the maxed ray-traced global illumination delivers the best image with frames to spare. For competitive-feel smoothness, run ray tracing off; for the prettiest Continent, leave it maxed at 140-180 fps.

RTX 5090 In SA

The RTX 5090 is currently stocked at Evetech in the R55,000-R65,000 band depending on model. For 1440p Witcher 3 it is overkill, making more sense if you also play at 4K. Pair it with a Ryzen 7 9800X3D and a 1440p 240Hz panel to use the frame rates it produces.

FAQ

What FPS does the RTX 5090 get in The Witcher 3 at 1440p?

Around 140-180 fps at 1440p Ultra with full ray tracing, and well past 200 fps with ray tracing disabled.

Do I need DLSS at 1440p on a 5090?

Not to hit high frame rates, but DLSS Quality with maxed ray tracing gives the best image while keeping frames to spare.

What monitor suits the RTX 5090 in Witcher 3 at 1440p?

A 1440p 240Hz panel, which the card can saturate with ray tracing off, or run maxed ray tracing at 140-180 fps for the best visuals.

TIP

the RTX 5090 has Witcher 3 headroom to spare; leave ray tracing maxed for the prettiest image at 140-180 fps and pair a 240Hz panel.
