I would like to know why i have this issues.
In closed areas the game runs fine (+60 fps) at high/ultra settings,but in open areas (city mostly) fps drops to 0 (and even crash tellling me that the drivers are restored)
Checking on the usage of GPU on open areas it works (more or less) between 5% to 30%,while in closed areas it works fine (80% to 99%)
Never had an issues with any other games (Witcher3,MGSPP,DA inquisition works like a charm)
I tried to reinstall the drivers,reinstall the game,toggle every possible graphic config in Fallout settings,still same problem.
GPU : AMD r380 4gb
Cpu intel i5 4460
Game stored in an SSD
