No shockwave lights...in FS9 so far with PMDG 737, Kirk Olson's F-16, Wilco Airbus, Wilco E-Jet V2. I have REX, AS6.5, Ultimate Terrain US, FSGenesis 38m LOD, GE Pro...again, not a problem anywhere but KBUF. Some Imagine products will do a micro quick "hang" about 15nm out but that's well known.
System is fresh/clean run O/O defrag etc once every 2 weeks, register cleaner etc. Average 40-50FPS in FS9. I only use the computer for FS9. I use Vista Ultimate 64bit.
It seems there are some last second texture builds when you are over the approach end of RWY23...just above the overrun. I tried day and night approaches and no difference. What are the texture sizes...1024? I have plenty of horsepower to run so I'm a bit confused. Is it possible to delete the fence completely?
