Why does that matter to a designer or photographer? Two words: addressable memory .
For existing Affinity users, the transition felt invisible—which is the highest compliment. One update, no data loss, no re-purchasing of tools. Just suddenly, files that used to make the app hesitate now opened with casual indifference.
In the broader creative software landscape, x64 has been standard for over a decade. But Affinity’s journey from a lightweight 32-bit underdog to a reflects its philosophy: remove technical ceilings so creatives can focus on craft, not crashes. affinity x64

For years, Affinity’s suite—Photo, Designer, and Publisher—was celebrated for being lean, fast, and refreshingly free of subscription bloat. But there was a quiet limitation lurking beneath that polish: for a long stretch, the Windows version remained a 32-bit application, even on 64-bit systems. It ran in emulation or compatibility layers, leaving performance on the table.
A 32-bit app can only access about 3.2GB of RAM, no matter how much you have installed. Open a few high-res RAW files, a multi-layer magazine layout, and a complex vector illustration simultaneously, and you hit a wall. Crashes. Stuttering. The dreaded “not enough memory” warning. One update, no data loss, no re-purchasing of tools
The shift to x64 also unlocked better multi-threading. Affinity’s core was always well-parallelized, but under a native 64-bit environment, thread scheduling and memory paging become dramatically more efficient. Exporting a 24-page brochure to PDF? It’ll use every core available without choking the UI thread.
