generally in games disappearing textures, this is mainly a problem of weak CPU ( example gta5 ) . But you have this may be anything at all. There is little information.

In General, the disappearing textures is a problem .
An example of this was for me personally .
(after Alt+tab was missing textures)
Definitely need to put all the drivers! The chipset and so on, and shouldn't be a problem!
Even if the CPU load none ~50%,
(also may be affected by some background processes and services from third-party developers)

I know the saying. Regarding gta5, even the themes were peace where blamed 100% CPU usage. And I had this same problem on the old Athlone to gta5. Changed percents, problem disappeared.

Put the process priority Manager, high
