Quick Answer

Zenless Zone Zero low FPS on RX 7900 XTX is usually a settings, driver, or frame-cap problem, not a reason to replace the GPU first. Use 120 fps or higher at 1440p, limited mostly by the monitor cap, then check overlays, thermals, and launcher repair before touching deeper Windows settings. In SA buying terms, RX 7900 XTX hardware sits around R20,000-R32,000 as a broad category band, so the fix should start with software before a new card.

Set A Clean FPS Baseline On RX 7900 XTX

Start with borderless fullscreen, the native panel resolution, V-Sync off for diagnosis, and a fixed cap that matches the screen: 60, 90, 120, or 144 Hz. On RX 7900 XTX, close capture overlays and keep the same combat route for each pass so the frame counter tells a useful story. If the frame rate jumps wildly, reduce shadows, reflections, and post-processing before lowering texture quality. Keep at least 20GB free on the game drive because patching and shader rebuilds can create stutter that looks like GPU weakness.

Driver And Temperature Checks

Install the current vendor driver from the normal NVIDIA, AMD, or Intel channel for your hardware, then restart before judging the result. Watch GPU temperature, hotspot readings where available, and CPU spikes during menus and combat. A desktop card that holds under about 80C while the game stays capped is usually healthy; a handheld should be judged against its power mode and fan profile. If the same FPS drop appears in another game, check the wider system instead of only Zenless Zone Zero.

FAQ

What FPS should RX 7900 XTX target in Zenless Zone Zero?

Use 120 fps or higher at 1440p, limited mostly by the monitor cap as the practical target. A stable capped frame rate feels better than a higher number that drops every time combat effects stack up.

Should SA players upgrade from RX 7900 XTX just for this issue?

No. With a broad local category band of R20,000-R32,000, replacing the GPU before file repair, driver cleanup, and overlay checks is a costly first move.

Which settings should be lowered first?

Lower shadows, reflections, and post-processing first, then retest the same scene. Texture quality should stay high if VRAM is not full.

Before checkout: Keep the FPS cap, driver version, and graphics preset written down, then compare RX 7900 XTX options only if the same low-FPS pattern remains after a clean repair.
