Ok so I was trying to use the Crysis64.exe instead of Crysis.exe, after changing to 32bit version it hooked up correctly.
The funny thing is that as I suspected the fps isn’t great but for some reason it still runs much smoother than most games I played. Others usually require that 75fps to get smooth headtracking but this one is still playable with much less.
Anyway thanks for the help, Crysis looks really nice with geometry 3d and I recommend anyone who has this game and vorpx to try it out. No major glitches found during brief testing, only some black bars(?) during cut scene but while player controlled looked really nice. :)
