How can I enable the precision x overlay on my 3090? I have checked button in bottom right and bound a hockey, but there is no response in game.

I believe there is a specific version of Precision for the 30XX series cards. Eventually the functionality of older cards and the 300xx will be merged into one application. Check the forum for the 30XX version if your not using at specific version and D/L it. Might help.

I have not used Px1 overlay much since getting my 3080 since nvidia has added their own performance overlay in geforce experience that I find works more consistently with more games and apps. However, in the past with Px1 overlay I found the most consistent way to get it to work was to set a hot key for OSD toggle in the settings, and making sure OSD + HWM light in the corner was illuminated prior to launching the game. That said, some games from the microsoft app store like Forza Horizon 4 would not even launch properly if I had HWM and OSD enabled, so there are definitely some compatibility issues.
