im not here to argue , but the ELS has an .ini file in which u can lower the ELS settings and furthermore maybe lower your settings in game as well .. but my guess is if you cant run ELS without lag then ur prob on some old hardware , heck i have 3 year old hardware , (older if u count rebrand) and my system still maxes out 1080p
ELS and Non ELS cars are the same difficulty to install in game but ive never made a non els so dont know if they are harder to make.
IF your having to change abunch of files or edit files other than .YTD for a car (aka textures or skins) than somethings not right lol , my ELS cars come with 3 main files , both .yfts for installing car and a .ytd for its textures and all 3 are drag and drop with instructions . Another 4th file is included for the ELS istelf and again drag and drop .
And Sometimes i will include a 5th file but the 5th or extra file , is for car skins , so say i have skins installed in car file well i will include extra skins incase you would like to swap them out , and swaping is again as easy as drag n drop.
So to sum it up , ELS is really easy yes there is 1 more file need for ELS cars which ... is the ELS file included but other than that its the same to install ELS and non so really there is zero need for modelers to make non els cars
