The RTX 5090 is the fastest consumer GPU available, so the real question for Kingdom Come: Deliverance is not whether it runs, but how far past your monitor's refresh rate it goes at 1440p.
Quick Answer
The RTX 5090 runs Kingdom Come: Deliverance at 1440p Ultra (Very High) at around 160-200 fps, with the CryEngine-based world fully maxed. At 1440p the card has plenty of headroom for a high-refresh monitor.
1440p Performance
At 1440p Very High, the RTX 5090 holds Kingdom Come: Deliverance around 160-200 fps. The original game's CryEngine is demanding in dense towns like Rattay, but the 5090 absorbs it, with the CPU becoming the limit in busy areas. Frame rates comfortably feed a 165Hz or 240Hz panel.
Settings And Upscaling
Max every setting at 1440p; the RTX 5090 has the headroom. The original game predates DLSS, so rely on native rendering, which is no problem here. Kingdom Come: Deliverance 2 adds DLSS support and is heavier, but the 5090 still holds high frame rates at 1440p in the sequel too.
RTX 5090 In SA
The RTX 5090 is currently stocked at Evetech in the R55,000-R65,000 band depending on model. For 1440p Kingdom Come it is overkill, suiting buyers who also play at 4K or want maximum future-proofing. Pair it with a Ryzen 7 9800X3D to keep frame times steady in dense towns.
FAQ
What FPS does the RTX 5090 get in Kingdom Come at 1440p?
Around 160-200 fps at 1440p Very High, dipping toward the CPU limit in dense towns like Rattay where the CryEngine works hardest.
Does Kingdom Come support DLSS?
The original predates DLSS and runs natively, which is fine on a 5090. Kingdom Come: Deliverance 2 adds DLSS and is heavier but still runs high at 1440p.
Is the RTX 5090 overkill for Kingdom Come at 1440p?
Yes, for this resolution. The card's value is at 4K or for the most demanding current titles; at 1440p it far exceeds the game's needs.
original Kingdom Come, the RTX 5090 runs natively at 160-200 fps at 1440p; dense towns like Rattay are CPU-limited, so a fast CPU helps.
