I have the latest directx 9.0c latest drivers latest physx uninstalled them and installed them still the same msg.

ok people this is what i did to fix it, i had this before with another game

download a program called driver sweeper, or something that can clean your drivers

uninstall all nvidia en physx related drivers. do not restart yet, use the driver sweeper first.

be sure to tick both nvidia (not chipset) an physx box, if it doesnt clean all on the first go , do it again.

reboot

install latest drivers, physx driver isnt needed as they come with the nvidia driver

enjoy the game

Confirmed it works now thank you

Yeah, nvidia/ati always had such problems when there is some part of oldest drivers left in teh system.

So i figured the problem! It's not the driver sweeper.Because I am with a CRT monitor and i have to lock resolutions with refresh rates so i can play with 100mhz.Anyway when I put the locked resolution the game won't run the sec I remove them it runs.It's not a problem though the game gets the right refresh rate for the resolution I just thought the guys who made the game would like to know.
