Help with playing Stalker Clear Skys

So i bought the game and the game said i met the minimum requirements to play the game but when ever i boot it up it says my graphics card dosent support sadder models v1.1. I'm currently using a ATI Raddeon 1300pro (sad i know) and was wondering if there were any driver updates that would fix this or if i could change some type of setting in the game.

Clear Sky is infamously buggy. You might try patching the game itself. If that doesn't work, updated your drivers.
