Heavy graphic bug (unplayable game) with ati x1300

[Darkspin 0]

Hi !

First, sorry if my problem is mentionned in another place, i've been shearching about it for an half-day on various forum but i didn't find anything about.

My config :

Intel Pentium 4 524

1GB DDR2 RAM

ATI Radeon X1300 HM 512MB

Drivers : 7-12 (but also tested with older drivers)

ArmA patched to 1.08 (but also tested with beta 1.09)

What happens ?

When I start the game, all is fuzziness, a lot of options are in black (unreadable), the menu seems to be very slow, my HD is always busy. I tried the -maxmem=512 tips, no result. I tried using different old graphic driver, no result. I tried the 1.09 beta patch, no result.

What to do ?

Thanks for your help, i'm lost...
