FSR 4 Explained: What Changed and Which Cards Support It

The biggest FSR 4 change happens in motion. AMD moved from FSR 3.1's algorithmic upscaling to a machine-learning model for RDNA 4 hardware, aiming for steadier fine detail as the camera moves. That hardware requirement is the part to check before you hunt through a game's menu.

Quick Answer

FSR 4 is AMD's machine-learning upscaler for RX 9000-series RDNA 4 graphics cards. It improves image stability over FSR 3.1 in supported games and can work beside frame generation, but support depends on the card, driver and game. As of July 2026, the Evetech card snapshot centred on R13,299, a useful local marker when comparing an RDNA 4 upgrade.

🧠 Machine learning changed the reconstruction

Upscaling renders the game below the display resolution and reconstructs a higher-resolution image. FSR 4 uses a trained model to make that reconstruction, which helps it understand patterns that often break up in motion.

Look at fences, hair, thin cables and distant signs while moving the camera. Those details reveal more than a still screenshot. Image quality also depends on the internal resolution, so start with the Quality preset before trying more aggressive modes.

🎮 RX 9000 hardware is the entry ticket

At launch, FSR 4 support is tied to AMD's RDNA 4 RX 9000-series cards. Older Radeon hardware can still use the upscaling versions supported by each game, but you should not assume that an FSR 3.1 menu option becomes FSR 4 on every card.

🖥️ Preset choice still matters

FSR 4 cannot create detail that disappears at a very low internal resolution. Quality mode is the sensible starting point at 1440p or 4K. Balanced can recover more performance, while Performance mode asks the reconstruction model to do much more work.

Frame generation is a separate step. It can make displayed motion smoother, but input response follows the underlying rendered frame rate. Get the base game comfortable first, then decide whether generated frames improve the experience.

Sharpening can alter the final picture too. Set it after choosing the FSR preset and judge it in motion, since an aggressive value can turn fine detail into shimmer.

Frequently Asked Questions

What is different about FSR 4 compared to FSR 3.1?

FSR 4 uses a machine-learning reconstruction model, while FSR 3.1 relies on an algorithmic approach.

Which graphics cards support FSR 4?

FSR 4 launched for AMD RDNA 4 hardware in the RX 9000 series. Check current driver and game support for the exact card.

Can older Radeon cards use FSR 4?

They can use older FSR paths where games support them, but native FSR 4 support is tied to RDNA 4 at launch.

Does FSR 4 support frame generation as well as upscaling?

It can be used alongside supported frame generation. They remain separate controls with different effects.
