1. Although the vehicle model limit in 0.3 is unlimited, if you use a large amount of vehicle models, you may notice parts of your mode become framey as vehicle models are dynamically loaded/unloaded. Keeping the number of vehicle models below 150 is a good idea*.
1. Although the textdraw string limit is 1024 characters, if colour codes (e.g. r) are used beyond the 255th character it may crash the client.
1. It is possible to show all Textdraws at the same time for one player, however this is not recommended.
1. To circumvent these limits, it is possible to use a streamer. Streamers work by only creating the objects/vehicles etc. that are close to players. See here (vehicles not supported, but there are streamers out there for those).
1. Due to client limitations only up to 51 actors may actually be shown at a time.
1. Vehicle ID's start at ID 1 and thus range from 1 to 1999, even if MAX_VEHICLES is 2000. Objects and player objects also start at ID 1.
