now i run the steam version i didn't get any problem on install vs gold edition . i get some addon in the package like RAAS, REX, Accufeel maybe i forget one .. i use Gex ut and fs passenger in high quality and i turn around 20 -25 fps it represent around +8 +10 fps and i just switch on steam loll maybe i'll try that trick in cfg. if i can gain more fps why not . so thx again for your answer
