(note that I didn’t use those alicemar.exe, cudafix or any application other than prehybrd.exe and hybridiz.exe, also, to play some games with hybrid physx on you’ll have to remove physxdevice.dll and some other files from the game folder [just rename them, or move them to another folder], depending on the game. Please refer to the link above)
