Low FPS with new AMD build?

Ok so this is not my issue its a friends but he doesn't really do forums etc so im asking on his behalf.

Basically he has just bought a new all AMD, AM5 pre-built system. 7900X CPU, 7900 XT GPU, 32GB DDR5 Corsair RAM(cant remember the exact speed) with a MSI B650 GAMING X AX motherboard.

Issue is that he's only getting around 50fps in Cyberpunk max settings 1440p, VSync off and RT off yet with my rig(5600X, 16GB RAM & RX 6750 XT)and exactly the same in-game setting im getting 80-90 fps at 1440p.

On Discord i helped him make sure his Windows 11 Pro was fully up to date, we updated his display driver to the latest 23.2.2, we installed the lates chipset driver for his CPU and updated his motherboard BIOS to the latest version.

I checked his AMD software and cant seem to see any setting that could be restricting his FPS, one thing i did notice though is that in the graphic section of the software is says he has 2 GPU's also when in game he brings up the AMD overlay is says that GPU 1 is being utilised 100% while GPU 2 is not being utilised at all, i guess GPU 2 is his integrated graphics?

I'm just really trying to pick you guys brains for anything we could try or may have missed?
