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 4K.
Quick Answer
The RTX 5090 runs Kingdom Come: Deliverance at 4K Ultra (Very High) at around 100-140 fps, the resolution where this card belongs. The CryEngine world looks its best at 4K with frame rates to spare.
4K Performance
At 4K Very High, the RTX 5090 holds Kingdom Come: Deliverance around 100-140 fps, dropping a little in dense towns like Rattay where the CPU contributes. This is the resolution that justifies the card, with the detailed medieval world rendered crisply at high frame rates.
Settings And Upscaling
Max all settings at 4K; the RTX 5090 has the power. The original game renders natively without DLSS, which is fine here. For Kingdom Come: Deliverance 2, which is heavier and supports DLSS, the 5090 still holds 90-120 fps at 4K with DLSS Quality enabled.
