Quick Answer

Yes, with a quick settings pass. Sea of Thieves is a stylised pirate sandbox whose water simulation and sail cloth are the real frame-cost, not texture detail, and the RTX 4070 Super (12GB VRAM) can hold 240fps at 1080p once you upscale sensibly and trim the two or three heaviest effects. Test a busy scene, not the menu, before you trust the counter.

Set Your 1080p Panel and Frame Cap First

Before touching in-game options, confirm Windows is actually outputting 1080p at your panel's full refresh. A 240fps target only feels right on a screen that can show 240Hz, so a 60Hz office monitor wastes the work. Set an in-game or driver cap a few frames below your refresh (237fps for a 240Hz target), enable G-Sync/FreeSync, then test one repeatable busy scene rather than an empty room.

Settings That Buy Sea of Thieves Frames

Water detail, shadows and sail-cloth simulation cost the most in Sea of Thieves. Drop water to High, shadows to Medium and clouds to Medium, leave textures high, and the open sea stays smooth even in a galleon fight. Re-test the same scene after each change and keep whatever holds the cap with the cleanest frame-time line.

TIP

"Test like a benchmark", body: "Record a 60-second run through the busiest area you can find and watch the 1 percent low, not the average. A 240 average with smooth lows beats a higher number that stutters in fights."

Pairing RTX 4070 Super for SA Builders

For South African buyers, RTX 4070 Super sits in the 1440p high-refresh bracket and is stocked at Evetech around the R13,000-R16,000 mark depending on the model and cooler. Feed it a 6-core CPU or better and 16GB of RAM so the card, not the rest of the PC, is the limit at 1080p. A 550-650W 80+ supply covers it comfortably with one 8-pin connector to spare.

FAQ

Can RTX 4070 Super really hold 240fps in Sea of Thieves?

Yes, with room to spare once you cap the frame rate and enable adaptive sync. Busy scenes are the test, not the menu.

Should I upscale or run native 1080p?

Use the built-in DLSS or FSR upscaler at Quality for high-fps targets; it usually adds 20-40% frames at 1080p with little visible loss. Run native only if you are already well above 240fps.

Do I need a 240Hz monitor to benefit?

Yes. A 240fps output only shows as 240fps on a 240Hz-or-higher panel with adaptive sync enabled. On a 60Hz screen you would be capped at 60fps regardless of the card.
