DX10 and 20 fps

Recommended Posts

Hi All


I have been getting lower FPS with PMDG 777 - 300 ER, which is around 19-22fps.


I have currently set 31 in fsx.cfg (in the sim) and have set vertical sync 1/2 refresh rate at 30 in nVidia inspector.


I am thinking of setting it to 21 in fsx.cfg and 1/3 in nvidia inspector (i.e. 20).


Will this help with a smoother flight ?.


My rig is 5 years old :-).




i7-920 @ 3.8GHz with Hyperthreading enabled

2x64 GB SSD, OS and FSX

nVidia GTS 660 2GB

Yes it will, Hari, but there are many parts of the fsx.cfg and Inspector which will possibly have a greater impact. You might post them here by reply, so that I and others can give you a more informed answer - ok!


You might also think about moving that nice 920 up to 4 or 4.2 gig: it will do it quite easily - even to 4.48 in my case, before moving to the 2600k. Here are some notes.


All the Best,




Edit:- Set the frame rate in the sim, (as Steve says below - leaving it set "Off" in Inspector. You don't want these two fighting.

Go for 20fps fixed in FSX and 1/3 if your monitor is 60Hz.
