I seem to be getting lower framerates and more jerkiness when flying in Europe than I do flying in North America.The only thing that I know is different is that I have GEX N. America and obviously not Europe yet.Could GEX make a difference?Thanks,Ron

Yes it could. GEX North America has autogen precisely aligned with the satellite files, therefore it can use less for a more effective result. The default textures don't include this so they have more autogen, which in turn decreases framerates. TL;DR version: Yes.

Thanks,I also see where UTX moving traffic takes a big hit.I am going to see what happens with it off.Ron
