Quick Answer

Atomic Heart at 1440p on an RTX 5090 is the ideal pairing for a high-refresh panel. On an RTX 5090, Atomic Heart runs effortlessly at high frame rates well above 144fps with everything maxed and ray tracing on. Frame rates stay extremely high with every setting maxed. The game's Mundfish engine is well optimised, and the 5090's 32GB GDDR7 and massive compute leave huge headroom even with ray tracing on. You will be limited by your monitor's refresh long before the card runs out of power, so pair it with a high-refresh panel to feel the frames.

What the RTX 5090 Delivers

The RTX 5090 is the flagship card, so Atomic Heart is never a challenge for it. With everything maxed and ray tracing enabled, the card holds high frame rates with room to spare. DLSS is not even needed at this tier, though enabling it pushes frame rates higher still if you want to feed a 240Hz panel. The bottleneck shifts to your CPU and monitor, not the GPU.

Match Your Monitor and CPU

To use these frame rates, pair the 5090 with a Ryzen 7 9800X3D and 32GB DDR5-6000 so the CPU keeps up, and a high-refresh monitor. Cap your frame rate just under the panel's refresh for the smoothest frame pacing; a 575W card runs cooler and quieter when it is not chasing pointless extra frames beyond what you can see.

Is the 5090 Overkill Here

For Atomic Heart alone, yes, a cheaper card like an RTX 5070 or 5080 also runs it superbly at 1440p. The 5090 makes sense if you also play the heaviest titles at 4K, want maximum future headroom, or run a 240Hz-plus panel. For this game specifically, the card is never the limit.

FAQ

What FPS does Atomic Heart get on an RTX 5090 at 1440p?

high frame rates well above 144fps with everything maxed and ray tracing on The 5090 has huge headroom in this well-optimised game, so your monitor's refresh and CPU become the limit before the GPU does. Cap FPS just under your panel's refresh for smooth pacing.

Do I need DLSS for Atomic Heart on a 5090?

No. The 5090 maxes Atomic Heart with ray tracing on without upscaling. Enable DLSS only if you want to push frame rates higher to feed a 240Hz-plus monitor; otherwise native looks superb.

Is the RTX 5090 overkill for Atomic Heart?

For this game alone, yes; an RTX 5070 or 5080 also runs it superbly at 1440p. The 5090 is worth it for the heaviest 4K titles, maximum future headroom, or a very high-refresh panel.

TIP

maxes Atomic Heart with headroom to spare; cap FPS just under your monitor's refresh for the smoothest pacing, and pair it with a Ryzen 7 9800X3D so the CPU keeps up.
