I too have just finished a second bite at upgrading after I couldn't get FSX (DX10 mode) working at the first attempt. Seems fine now but had to deal with the following.. - The ACM for the VRS Superbug only works in Windows 7 compatibility mode, otherwise it hangs and then eventually crashes due to a compiler timeout. - REX Essential Overdrive only works well in Windows 7 compatibility mode, otherwise it was taking literally half an hour to initialise. - FSX would CTD if you ran it with the 'maximised' setting in FSX.CFG set to 1. Although switching to full-screen mode is largely fine as long as you don't start in it. Changing that flag and deleting the shaders were all I had to change from my Windows 7 setup. - Auto GPU scaling doesn't seem to work (I run FSX at 1920x1080 on a 1900x1200 panel), although I believe this is a nVidia driver issue? The workaround is easy enough though.

I too couldn't get it to work either on a pristine install of both Windows 10 (latest nvidia drivers etc) and FSX Acceleration in DX10 mode (no third party add-ons or NI installed at this stage). Typically it would CTD with errors in kernelbase.dll or fsxui.dll after alot of flickering of the desktop/black screen after hitting 'Fly Now'. This was with trying all manner of compatibility settings and I run it as admin as a matter of course anyway. Ended up reinstalling Windows 7 in the end.

Funnily enough i've had all kinds of problems too. Upgraded and FSX didn't work. Did clean Windows 10 and FSX install (FSX + Acceleration) and it worked about 1 time out of 10 in either DX9 or DX10 mode. Tried all kinds of compatibility mode combinations with no decent results. Generally it crashed to desktop on going into 'Fly Now' (usually either kernelbase.dll or fsxui.dll were the culprits). Am not part way through reinstalling my system back on Windows 7. A pity, as otherwise I like Windows 10 but I need my FSX fix! This was with a nvidia 680 graphics card and latest drivers by the way.

Anyone know where you can get installers for prior versions from? I updated to 2.3 and (unless my mind is playing tricks) flashing water tiles seems worse than I remember. Was going to downgrade but the only other version I've got an installer for is ancient (1.4).
