FSX and Vsync

Hey guys, 

So like most people i use Nvidea Inspector with FSX 

 I have a question Regarding The Vsync Part of Nvidea inspector 

In my FSX.CFG i dont have any Forcefullscreenvsync tweaks active as i have found it affects fps. 

If i dont have any vsync tweaks active what should be the setting in nvidea inspector ?? Eg use 3d application setting setting or 1/2 Refrsh rate just to name a few. 

Which Value will imporve FPS and also Have no tearing ?? apologies if this is a silly question but could some one shed some light into This for me ??

Also What should the Texturebandwithmult setting be set to in the FSX.CFG? does the tweak imporve blurries ?  I Have FPS locked to 30 in Nvidea isspector and currently i have TBM =80 

Could anyone shred some light
