Alpha PATCH v1.06.17582 with Desastersoft Helmut Wick vs. J. C. Dundas campaign

[skouras]

it will sound stupid
but i begin today the 609sq campaign [select to install for high pc]
and i get a terrible drop in fps
all the german campaigns running fine so far
so i exit the game and restart it
and select again the 609sq campaign
for some reason i get a big fps boost this time and running fine
anyway if someone experience this with this patch just close the game and enter again
