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.
IMO changing iBlurDeferredShadowMask has a bigger impact on smoothing out the shadows than increasing the map resolution (and doesn't have stability issues).
Wanna see your performance take a dump but see the shadows look even better? Set that number to 8192 instead of 4096. Don't say I didn't warn you, though. Enjoy the slide show.
