The RX 9070 XT is a confident 1440p performer, so hitching straight after the swap is a software story. Leftover NVIDIA or older Radeon driver bits, Smart Access Memory left disabled, and an uncapped frame rate are the three things to rule out first.

Quick Answer

Stutter after an RX 9070 XT upgrade usually traces to a driver conflict or Smart Access Memory being off, not the card: clean-install the Adrenalin driver, enable SAM/Resizable BAR in BIOS, and cap your frame rate. The RX 9070 XT runs a smooth 100-130 fps at 1440p Ultra once SAM is on and the old GPU driver is fully removed.

Clean Adrenalin Install And SAM

Remove the previous driver with DDU in safe mode, then install the latest AMD Adrenalin package fresh. Enable Smart Access Memory, which is Resizable BAR plus Above 4G Decoding, in BIOS; the 9070 XT gains real 1% low consistency from it. The RX 9070 XT currently sits around R15,000 to R18,000 at Evetech depending on the model.

Anti-Lag, Frame Caps And FreeSync

Set a frame cap with Radeon Chill or an in-game limiter a few fps below your panel's refresh and enable FreeSync to remove tearing judder. Test with Anti-Lag toggled both ways, since a few titles dislike it. Keep the power mode at the default Balanced or Performance preset rather than a custom undervolt while you diagnose.

Power And Thermals In SA Cases

Confirm both 8-pin connectors are seated and the PSU is a genuine 750W 80+ Gold unit; transient drops on a weak supply look exactly like stutter. In a hot room, keep the card under about 80C junction and ensure intake airflow reaches the GPU. Sawing clocks in Adrenalin's overlay indicate thermal throttling, not a driver bug.

FAQ

How much is an RX 9070 XT in South Africa?

Partner RX 9070 XT cards sit around R15,000 to R18,000 at Evetech. Pair it with a quality 750W 80+ Gold PSU and a case with solid front intake for steady clocks.

What is Smart Access Memory and do I need it?

SAM is AMD's branding for Resizable BAR. It lets the CPU access the full GPU frame buffer and improves 1% lows on the 9070 XT, so enable it in BIOS for the best frame pacing.

What FPS does the RX 9070 XT hit at 1440p?

Expect 100-130 fps at 1440p Ultra in current AAA titles, higher with FSR enabled. It pairs naturally with a 165Hz or 240Hz 1440p panel for high-refresh gaming.

TIP

" Remove the old driver with DDU, enable Smart Access Memory in BIOS, and cap frames just under your refresh; the RX 9070 XT paces cleanly once SAM is on.
