Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I agree with the others. The GF4 MX4000 lacks any hardware support whatsoever for DX8.1-compliant vertex and pixel shaders, since it's only a DX7-generation chip to begin with. You'll need full hardware support for DX8.1 in order to even play DeusEX 2 at all. And though the GF3 and GF4 Ti series will play those games at mediocre framerates, now is clearly the time to upgrade that MX4000 to a FX5900 or an R9800Pro.
