For me it looks like MTA is not able to handle some of modified textures correctly.@Sp1K3PR04 what u mean to play the game on graphic card , is it possible my game runnied in the CPU graphic card?
Make sure that your game loads on your graphic card (force it basically).
Also you opened ENB panel have you tried to edit the values there to see if it makes it better.
Also make sure you got your directx 2.0 on a valid source.
you have to re download GTA SA again.IK THAT already did and fixed (reinstalled regular mods) I want this amazing mods in my MTA without those GLITCH's
