In order to optimize the game, Rockstar slows the player down in specific areas of the map using zones which have "extra air resistance". This is done through "cull.ipl", which contains all of the cull zones on the map, one of the possible flags for a cull zone is "ExtraAirResistance".
As a result your vehicle get slowed down on these zones of the map, both on acceleration and top speed.
This simple cleo script disables this optimisation as it is no longer necessary on modern hardware. As this version of the mod is a script, it is compatible with total conversion mods that replace "cull.ipl" file such as Proper Fixes.

Update v1.1:
Added ini file with the option to disable on SAMP;
Now it applies the patch only once;
Removed need for CLEO+.
Notes:
The original mod idea is from TJGM, the original mod work by replacing "cull.ipl" file, this could cause some incompatibilities with total conversions mod that change the same file such as Proper Fixes, this version instead is a simple cleo script that achieves the same result without replacing any files, for sake of simplicity i used some words of his original post, to get more details on it checkout his post: https://gtaforums.com/topic/999800-no-extra-air-resistance/. again thanks to TJGM for his excelent work;
