Tekken 8 is a fighting game, and fighting games run on a hard 60 fps gameplay lock for fairness, the engine simulates matches at 60 fps regardless of your hardware. That single fact reshapes the whole RTX 5090 question at 1440p.

Quick Answer

Yes, the RTX 5090 runs Tekken 8 at 1440p maxed without breaking a sweat, but gameplay itself is locked to 60 fps by design, so extra GPU power goes into visual settings and menu smoothness, not higher in-match frame rates. Because of that lock, a R7,500 RTX 5060 already maxes Tekken 8 at 1440p, the 5090 is heavy overkill for this game alone.

Why more GPU does not mean more fps in Tekken 8

Tekken 8's netcode and match simulation run at a fixed 60 fps so online play stays fair and deterministic. No GPU, including the 5090, raises that in-match number, the card only affects whether you can max settings and how smooth menus and replays feel. At 1440p maxed, even a mid-range card holds the 60 fps gameplay target with ease, which is exactly the point: Tekken 8 is a low-demand title by flagship standards.

What actually improves your Tekken 8 experience

Since frames are fixed, prioritise connection quality and a low-latency display. A 1440p panel with low input lag, a wired Ethernet connection over your fibre line, and a controller or fightstick matter far more than GPU tier for ranked play. If you want the 5090, justify it with other games, for Tekken 8 specifically, an RTX 5060 maxes 1440p and frees budget for a quality fightstick or a faster monitor.

TIP

Tekken 8 on a wired Ethernet connection rather than Wi-Fi, stable rollback netcode depends far more on your link than on your GPU.
