Quick Answer

If Stellar Blade feels slow on a RX 7900 XTX, the cause is almost always settings or driver state, not the 24GB card. Update to Adrenalin 25.x, enable FSR Quality, and cap frames to your panel; a RX 7900 XTX at around R20,500 should hold a high, steady frame rate at its target resolution. Low FPS here points to a CPU bottleneck, background load, or a Windows power plan stuck on Balanced.

Find the real bottleneck on a RX 7900 XTX

Open the in-game or driver overlay and watch GPU usage. If the RX 7900 XTX sits below 95% while frames are low, the CPU or RAM is the limit, not the card. If it pins at 99% with low frames, your settings are simply too aggressive for the target resolution. Set the Windows power plan to High Performance and close browsers and overlays, which alone can recover 10-20fps on a RX 7900 XTX.

Settings and driver fixes for a RX 7900 XTX

Do a clean Adrenalin 25.x install with DDU. In Stellar Blade, enable FSR Quality, set shadows and effects to High rather than Ultra, and turn off any unused motion blur. Confirm Resizable BAR is on in BIOS for a few extra percent, and verify 32GB system RAM so the RX 7900 XTX is never starved. Cap frames to your refresh rate to stabilise 1% lows; uneven frame times read as "low FPS" even when the average is high.

FAQ

What FPS should a RX 7900 XTX get in Stellar Blade?

With FSR Quality a RX 7900 XTX should comfortably exceed 60fps at its native resolution, often pushing well past 100fps at 1080p. If you are far below that, look at the CPU, RAM, and power plan first.

Does FSR hurt image quality on a RX 7900 XTX?

At Quality mode the difference is minimal and the FPS gain is large. On a RX 7900 XTX, FSR Quality is the easiest way to lift frame rate in Stellar Blade with almost no visible loss.

Will more RAM fix low FPS on a RX 7900 XTX?

If you are on 16GB, moving to 32GB helps Stellar Blade's stutter and 1% lows on a RX 7900 XTX. The card is rarely the issue; feeding it with enough fast RAM and a strong CPU is what unlocks its frame rate.

Get the most from your RX 7900 XTX Pair a RX 7900 XTX with 32GB of RAM and a high-refresh panel from Evetech so Stellar Blade runs at the frame rate this card was built to deliver.
