I used to host a Namalsk server with many custom things, so it has become habit to sift around the updates to put some numbers on my speculation. Then I saw this: _fpsbias = (60-(60-(diag_fpsmin min 60))/1.5)/60; _maxControlledZombies = 30 or 40 _maxControlledZombies = round(dayz_maxLocalZombies * _fpsbias); _maxManModels = round(dayz_maxMaxModels * _fpsbias); _maxWeaponHolders = round(dayz_maxMaxWeaponHolders * _fpsbias); Now... It seems like the developers are trying to limit zombies and loot spawns to increase performance. In doing this they seem to have decreased zombie activity for lower framerates (Lower difficulty, higher framerate). And they are reducing the amount of loot that spawns for these people (higher difficulty, possibly higher framerate). I don't know if this code is in effect at the moment (definitely not //commented out), but here are some calculations I have made regarding how this may affect you based on your framerate: I am assuming that _maxControlledZombies is the number of zombies doing movements or running towards you at one time (Aggro) and _maxWeaponHolders is the max amount of loot piles that is capable of being on the ground at any given time. 60fps minimum: _fpsbias = (60-(60-60)/1.5)/60 = 1.00 Max Zombie aggros: 40 100% Maximum Loot 30fps minimum: _fpsbias = (60-(60-30)/1.5)/60 = 0.67 Max Zombie aggros: 27 66.7% Maximum Loot 10fps minimum: _fpsbias = (60-(60-10)/1.5)/60 = 0.44 Max Zombie aggros: 18 44.4% Maximum Loot If any devs could shine light on this process - it would be much appreciated. My coding abilities are not the best, so if any mod-makers know what is going on, please speak up.
