Low FPS on Hidden And Dangerous Deluxe

So i downloaded and installed Hidden & Dangerous Deluxe on my win10 pc but im having issues with FPS as they seem capped to 16, i tried changing up video settings, NVidia control panel settings and compatibilty modes/run as admin but nothing works. any ideas?

I don't really know but maybe in task manager give it a higher priority?

I dont know if it's possible on w10 but maybe try run as administrator compatibility with Windows XP?

I tried changing priority but it had no results, i have tried running as admin and every compatibility mode, still no luck

maybe you can post a screenshot of your graphic settings in the game?
