While I'm not experiencing stutters, I cannot seem to solve the "white artifacts" while zipping around.
I've searched within avsim a bunch and have implemented suggested fixes but to no avail.
Is it a big deal? Not really, it is just annoying at night over water while landing on a CV.

add: That tube was captured a year ago from a EVGA GTX 590 Classified. Since then I've built a new sys that's using the aforementioned GTX 570's in SLI and the artifacting is not so prevelant but still happens.
