can't see anything obvious in conf- but i'm not up on integrated graphics cards
you are on quite high settings, have you tried dropping them at all?
also what settings are you using in SAS selector? try dropping ram amount, not using 4gb address space, disable mod cache??
i think these things might be 'grabbing at straws' and a reinstall might be in order.
before you do this i'd recommend the hard drive check i mentioned earlier and a full virus scan wouldn't do any harm.
then check at each stage of the install, 4.101, UP3, DBW.
only if all is good here add any other mods.
time consuming i know but being methodical pays off in the long run
you might be able to add another cockpit mod as a temp fix as for mustang
