Not everyone has it, my brother is playing on a amd 7850 with a icore 3ghz and this doesnt happen to him, (his pc is weaker than mine) i cant even play for over 30m without getting stuterring in fps, i researched and this is a old problem that affected players even in arma 2, but there is no way to fix it, ( Also i check the threads for while playing the game is using 50% of my cpu, and 70% of memory, also the game doesnt heat the cpus that dont go over 65º and the graphic card doesnt go over70º so its not a heating issue, it feels like, the more i play the more the game is leaving on memory making it slower, restarting computer fixes it, but if i dont restart the computer, even if i try the game like 3-4h later, i will still lag, and worse, the lag follows on deskopt i get mouse suttering and the whole pc gets slow and the mouse takes time to recognize in browsers to choose options.
