SOME ADDONS CAUSE GAME CRASH:

(Maybe ADDON STREAM Peds can crash your game)

IF YOUR GAME'S STILL DON'T WORKS, MOVE ALL YOUR ADDON VEHICLES TO ANOTHER FOLDER, THEN TEST 'EM, 1 BY 1 OR ANYTHING YOU WANT, BUT JUST ONE ADDON CAN CRASH YOUR GAME, SO KEEP TESTING.

Also, remember a gameconfig.xml depends on your mods, this maybe won't work for you, for that, you need to test values by yourself.

DO NOT REPLACE EXTRATITLEUPDATE.META, leave it vanilla.

Willief23 searched for the highest values to gameconfig, so I added 'em almost all, vehicles no because it crashes my R* Clip Recorder after 1 clip recorded.
I use 100 Addons (100 addons folders, more than 150 addon vehicles models in all folders)

I just share it here to all the people that can't play the game with the new update (with addons). Hope It Works for you. SCREENSHOTS ARE JUST FOR ATRACT.
