i'm sure some people have no troubles.
and others cant run it at all.
i'm somewhere in between. it runs sometimes and blue screens other times.
most recent bsod's:
page_fault_in_non_paged_area
and
kmode_exception_not_handled
they both refer to nv4_disp.dll which is an nVidia display driver file.
meaning: bad driver.
but i've tried many 43.30, 41.09. 30.82, 31.00 and more. none have made much difference.
i now have 31.00 (from msi) and it had the above problems, but i put VERTICAL SYNC to ALWAYS OFF in the OPEN GL SETTINGS (right click on desktop, settings, advanced, GeForce Tab, additional props -or something), and things have improved.
theres lots of little tweaks to do to the game and to your pc that may improve things. and getting the right display driver makes a difference.
but most systems are different and need different drivers.
one other thing that may cause probs is bad hardware - memory/graphics card/procesor/???
from what i've seen gp4 is better than gp3 in detail and other things (but not track selection & other things) and worth atleast some effort to get it going.
well. goo luk
