Not at the command station but I've also noted "stuttering" or "flashing" around clouds... To the effect of strobe/seizure inducing... My rig should be more than enough hardware to handle the load requirements, but something may need to be tweeked.
I'll try to get a DXdiag & film tonight. But it's strange that my Ctrl-I frame rate indication doesn't drop below 59.
I also found dirty choppiness around CV ack the other night... Very strange and almost game breaking. DXDIAG, Film, screenshots, what would best serve you guys to check it out?
