Quick Answer

If Stellar Blade feels slow on a RTX 4070, the cause is almost always settings or driver state, not the 12GB card. Update to GeForce 566-series or newer, enable DLSS Quality, and cap frames to your panel; a RTX 4070 at around R12,500 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 RTX 4070

Open the in-game or driver overlay and watch GPU usage. If the RTX 4070 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 RTX 4070.

Settings and driver fixes for a RTX 4070

Do a clean GeForce 566-series or newer install with DDU. In Stellar Blade, enable DLSS 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 RTX 4070 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 RTX 4070 get in Stellar Blade?

With DLSS Quality a RTX 4070 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 DLSS hurt image quality on a RTX 4070?

At Quality mode the difference is minimal and the FPS gain is large. On a RTX 4070, DLSS 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 RTX 4070?

If you are on 16GB, moving to 32GB helps Stellar Blade's stutter and 1% lows on a RTX 4070. 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 RTX 4070 Pair a RTX 4070 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.
