Solution for Stutters & Pauses (updated for SU5)

I have no stutters, only dropped frames if I drop below 30 fps but even then they are only really apparent if I make quick movements. Anyone can get good numbers at 8000 feet but my advice is that folk shoud adjust their settings to still run well on approaches all the way down to the numbers. An emergency fix could be turning off volumetric effects, a one click affair if you’r flying in dev mode.

Whether you’re GPU or CPU limited Babu’s guide is the best I’ve come across yet.
