Is it just me or is this new version 1.3 a little harder on FPS ? I've just migrated from XP to 7 and changed my Geforce 9800GT 512mb for an overclocked GTX460 1gb, and I get worse performance than before with the 707. Something just doesn't add up... Cheers Nico

Backup your fsx.cfg, then upload your fsx.cfg here and run it - http://www.venetubo.com/fsx.html

It might find things you haven't got activated in the CFG that is better for the faster gfx card. Did wonders for mine, try "conservative" first, then try normal.

It may activate vsync (good) but sometimes vsync can make your fsx jump around  (some cards only) so you may need to run FSX via the FSLimiter prog (http://www.simforums.com/forums/topic29685.html ) which stops any erratic behaviour.
