RTX 5090 Hearts of Iron 4 performance - what to expect at 1440p

At 1440p, Hearts of Iron 4 looks sharper but still does not behave like a pure graphics-card test. If you are eyeing an RTX 5090 in South Africa, the smart move is to check the whole setup, because this game spends most of its time on simulation, not rendering.

Quick Answer

Hearts of Iron 4 at 1440p clears 165fps easily on an RTX 5090, but campaign speed depends on CPU single-thread performance, memory and mods, not the GPU. The card costs roughly R49,999 to R64,999 at Evetech, so it makes sense only as part of a broader high-end build.

1440p Does Not Remove The CPU Question

Moving to 1440p gives the GPU more work than 1080p, but Hearts of Iron 4 still spends most of its time on game logic. Large wars, busy fronts and modded campaigns make the rest of the PC matter as much as the card. Do not read the RTX 5090 name as an automatic fix: check how your current machine behaves in long campaigns. If the map view is clear but time progression feels heavy, the GPU is not the missing piece. If you also play demanding 1440p titles, the RTX 5090 becomes a much stronger all-round choice.

Compatibility Around Long Campaigns

Long strategy sessions reward a PC that stays cool and quiet. Confirm card length, slot thickness, cable clearance and an 850W-1000W PSU plan before buying. Check the monitor connection too, since a good 1440p panel should run at its proper refresh. For Hearts of Iron 4 specifically, money spent on a faster CPU and quick RAM improves late-game tick rate more than any graphics upgrade.

FAQ

What frame rate does Hearts of Iron 4 hit at 1440p on an RTX 5090?

Comfortably above 165fps, since rendering is light. The number that matters for strategy players is late-game tick speed, which is CPU-bound rather than GPU-bound.

Is the RTX 5090 worth it for Hearts of Iron 4 at 1440p?

Not for the game alone. A strong CPU and fast RAM do far more for campaign speed. The roughly R49,999-plus card is only justified across a wider demanding library.

What upgrade speeds up Hearts of Iron 4 campaigns?

A CPU with high single-thread performance, fast DDR5 and an NVMe SSD. These cut the slowdown of large wars and heavy mods far more effectively than a new GPU.
