Since last update (0.34.115106) I have long fps drops connected with more memory usage (I have 8 GB) and flickering textures (usually sprayed items like sprayed parts of M4). With my nVidia Fermi VGA (1GB N560GTX-Ti) on my game quality settings (LOW-NORMAL) I have usually aprox 60fps, but after 20-40 minutes fps decrease under playable minimum - 30 fps. Near 15 fps are problems connected with long freezes - Dayz stop working message or recomendation of stoping dayz for heavy RAM usage.
My solution is restart game (clear textures from memory) and reconect to diferent server. And i have 60fps back for at least 20 min. {F30226}
