compatability issues with 64 bit vista?

I've certainly come across problems with both applications and games when using Vista x64. Most applications that do have a problem state quite clearly they aren't meant for 64-bit, but really the programs that do so usually have a separate 64-bit version. There are some that don't fit that pattern, but apparently none were notable enough for me to recall.

I have come across two specific game issues, however, as I test a fairly large amount of titles on Vista.

1) ArMA/Armed Assault - appears to have a bug with ATI drivers + Vista x64
Note: I believe this is a known issue and may be fixed, but meanwhile it might be fixable by using either an older driver or the default driver (may also be possible to mod a driver)

2) Brothers in Arms: Earned in Blood - cannot install because of Starforce copy protection
Note: This is a known issue and it seems unlikely it will be fixed officially (at least for this specific case)

ok, so no other games? I suppose the older they are the less likely it is they will work generally, so anyone know any others?

There's a list going on over at the H, but it's a pretty good bet that anything with a 16-bit installer is going to require a workaround if not a virtual machine. The in-between titles are hit the hardest (not too old, not too new).

ok i'll look
