I find out why GTA V crash on Windows 10, and was perfectly working on Win 7 64.
first system: 8350 fx 4.2ghz, 16gb, 280x catalyst 15.7, 15.7.1, 15.8 , samsung ssd, GTA V installed on Western digital 1TB my passport slim external 1.8 inch 5400 rpm.( this external hdd has about 89mb in hdtach)
second: intel 3770k, 16gb, intel ssd, nvidia GTX 690 GTA V installed on Western digital 1TB my passport slim external 1.8 inch 5400 rpm
third: intel i7 920, 16gb, adata ssd, r9 290 GTA V installed on Western digital 1TB my passport slim external 1.8 inch 5400 rpm
this is the error:

I could play 5 minutes, or 30 minutes, or an hour, then image freeze, sound remain on for about 1 minute after, then sound off, gta V encounter an error message appear and so on.
The crashes appear often if i tried to do an mission.
FIX for all 3 sistems, wd 1TB 1.8" is not powerfull enough for this game with TEXTURES to VERY HIGH, i put textures to HIGH, game not freeze for about 3 days not.
Before that it freeze for maybe 30 times in 5 hours, after every freeze SAVE was broken, must restart PC to play again.
Before this fix i tried everything, reinstall 20 times, update mainboard bios, stop my overclock, tried 15.6 beta driver on ati , and others on nvidia 690, i tough that Win10 and gpu drivers is the culprit.
CONCLUSION-THIS external hdd is not powerfully enough to sustain textures set to VERY HIGH.( it has 8mb buffer, 5400 speed)
