Return of Reckoning

Hello all,
Camoe here

I was wondering if anyone have any clue what could it have been or anyone of you out there got same issue.
I was asking ppl around in-game if anyone got same issue, and noone got it...

It happening every time i go to Windows desktop when i'am in-game, and enter war.exe again...
Happens: And game laggs for next 5sec.

So my question is, any ideas how fix, any clue what could it be (directX,drivers,etc...)

Thanks for all the reply's
Sorry for ugly english...

Cheers!

Have you tried this in windowed mode also?

i get something like this but only for about 1 second aftr alt tabbing. my guess its just the system switching priorities. for me it goes back to normal in thge blink of an eye tho.
