Quick Answer
On an RTX 5080, Atomic Heart runs very well: SA gamers can expect well over 100 fps at 1440p ultra and roughly 70-100 fps at 4K ultra, with ray tracing on plus quality upscaling keeping 4K above 60 fps. The 5080 is comfortably overpowered for this title at 1440p.
What To Expect At Each Resolution
Atomic Heart is a polished but not punishing shooter, and the RTX 5080 handles it with ease. At 1440p ultra you will sit well above 100 fps, easily saturating a high-refresh panel. At 4K ultra, expect roughly 70-100 fps depending on the scene, which is smooth for a single-player shooter. Turning on ray tracing lowers those numbers, but quality upscaling restores 4K above 60 fps comfortably.
Because the 5080 has ample power and VRAM here, frame pacing stays consistent, so the experience feels smooth rather than just high on average.
Getting The Most From The 5080
For the best balance, run 4K with quality upscaling and ray tracing for a great-looking 60+ fps experience, or 1440p native for very high frame rates on a fast panel. Ensure your CPU is a modern 6-or-8-core so it does not cap the 5080 at 1440p, and keep case airflow good so the card holds clocks. A 750-850W PSU suits a 5080 build, and an 850W ATX 3.1 unit is the safe pick.
FAQ
What FPS does Atomic Heart get on an RTX 5080?
Well over 100 fps at 1440p ultra and roughly 70-100 fps at 4K ultra. With ray tracing and quality upscaling, 4K stays above 60 fps, so the 5080 handles the game with ease.
Should I use ray tracing on the 5080 in Atomic Heart?
You can. Ray tracing lowers frame rates, but quality upscaling keeps 4K above 60 fps, so you get the visual upgrade while staying smooth. At 1440p you have plenty of headroom for it.
Will my CPU bottleneck the 5080 at 1440p?
It can if it is older. Pair the 5080 with a modern 6-or-8-core CPU so it does not cap frames at 1440p, where a weak CPU would limit the card before the GPU is the bottleneck.
5080, run Atomic Heart at 4K with quality upscaling and ray tracing for a great-looking 60+ fps, or 1440p native to fully use a high-refresh panel.
