cgminer has problems with gfx memory beign locked or something

[dustofdeath]

Iv noticed that  it seems to  fil after iv had firefox or anythigg that uses gfx card,  open.

It starts to lag alot and speeds are as low as 10-30khs.

This far only reboots seem to have fixed this - or when i remove the --thread-concurrency 8192.

But that results in bad mining and rejected shares/low wu.


Smetiems when i close al lthe gfc using apps ( liek firefox Oo) it starts up fine - but quite a few tiems... nothing helps.

Its as if video memory is full and not getting flushed or something.

Any idea whats going on and how to fix that.. constant reboots just for that are seriously annoying.
