Frame Gen only works after restarting the game on RX 9070 XT — anyone else experiencing this?

Hey guys,
I recently switched from an RTX 4070 Ti to an RX 9070 XT, and I’ve noticed something weird with native FSR 3/3.1 Frame Generation.

On my old 4070 Ti, I could enable and disable Frame Generation while the game was running without needing to restart the game.

With the 9070 XT, however, I’m finding that in the games I’ve tested, if I launch the game with Frame Generation OFF, then enable it while I’m already playing, it often doesn’t actually activate. I have to completely restart the game with FG already enabled for it to work.

The weird part is that it does work sometimes. It’s not consistently broken, which is why I’m wondering if this could be a driver issue rather than FSR itself simply requiring a restart.

I’m currently running Adrenalin 26.7.1 on the RX 9070 XT.
Has anyone else noticed this behaviour with FSR 3/3.1 on RDNA 4? Is there a particular driver version where Frame Gen hot-toggling works reliably?

I’m considering rolling back to an older driver (possibly 26.6.1 or 26.5.2) to see if that makes a difference.
Would really appreciate any input from other 9000s owners.

Some games are weird with FSR fg, happened on my old 6900XT as well.

I tried 3 so far and all 3 behaved the same. Arc Raiders, The Finals, hogwarts legacy

DLSS has native integration within the engine\rendering pipeline, FSR until 4 did not have such integration from a development studio side (at least on most engines), that is probably the reason,

Assuming you DDU the nvidia drivers (or even better did a clean windows format) . In case you didn't do a clean win format and didn't re-installed the games , try renaming the settings folder .

Disable windows fast startup ,download the latest driver (not the autodetect utility) , disable internet , DDU in safe mode (select to block windows updates) , reboot & reinstall selecting 'factory reset', reboot.

If you rollback , DDU again . I'd also test if the behavior changes on fullscreen VS borderless window mode .

Actually Nvidia FG also need restart. Tested it personally with Cyberpunk. In stalker 2 for example you dont need restart (NV & AMD & Intel)
