GSC2013 Triple screen - issues / tips / help

[Rob Fitness]

I just in the last couple of days have gone to triple screens and have now a heap of issues arrising.

at first it ran pretty good after sacrificing some eycandy for framerate, but today its gone to poop!

- im suffer stutters big time
- car textures are flashing when in the pits on all cars
- the replay cams dont seem to use multi-view either

has anyone got some ideas?

i already run full proc high prio, have tried with nothing else running etc. with the stutters is like just appeared out of nowhere.

edit:
windows 7 64 bit
16gb ram
GTX590
i5 at 4k OC water cooled (game has always been run at this with no issues)
