i get many crashes and restore driver in warframe. the game uses physx. back to 347,25 and its better but get crahes in void also. And because i play assassin's creed unity. There is a bug in all helix-missions not showing correct. not repaired since 347.25. last driver 353.12 very very unstabel and get computer systemfreezes. had to reset. I noticed, that the unstable crashes and freezes are only in warframe and i set in physx from auto (what commented as to be best) to physx set to my GPU. I noticed only one crash of the game in 24 hours. Thats much better now.
