Graphics driver is one of the components I habitually pay extra attention to since NEW doesn’t necessarily mean GOOD at the same time in this sector in particular. After upgrading to P3Dv2.4, I’ve been using the 344.11 driver as it offers a noticeable improvement over older and even newer versions under the P3D platform.
Today, I just have it replaced by the newest 344.65 after testing the new driver for a few days. Frankly, I might not see measurable improvement accordingly, but overall smoothness enhancement is observable.
There are people reporting that the new driver resolved the SLI compatibility issue. Unfortunately, it is not the case in my setup.
BTW, during the earlier installation of the P3Dv2.4, I found most induced stutters turning out to be caused by the many additional Orbx addons rather than by the simulator itself.
Sadly, the world isn’t perfect. Neither does the virtual world.
