I play on a 60hz monitor and have no issues with excessive pop-in or such glitches.
Edit: It's your console or game copy by the way. Pop-in and texture glitches is basically the game not loading textures properly or fast enough. Your TV plays no part in this. What you're doing is hitting a shoe with a hammer and wondering why the laces won't tie.
Would you rather have a car not spawn, or have it spawn and collide with the world, blowing up in your face and killing you in the process, making you come here whining about how cheats should be denied when there isn't room to spawn them?
Ladies and gentlemen. THIS is why I believe that the cops in GTAV are AWESOME.
PLEASE be warned! The footage contained in the link below contains a high-speed chase which ends in cops shooting the perpetrator. He did not survive. While no gore is visible in the video you can hear shots being fired.
