GTA V Lag spikes

[EliThePikachu]

Sorry if i'm in the wrong category on this page, but anyways i just got GTA V about 2 days ago and i didn't get a lot of lag but just a few lag spikes (average of 25-30 fps with i5 6400 2.7ghz with HD 530 Graphics) and i started experiencing lag spikes as i started getting more into the missions in single player. so i asked my friend (pretty good with computers) i asked him if it could of been my ram (i get kinda high usage of ram 24-43%my ram is Crucial Ballistix Sport LT 2400 but my motherboard clocks it down to 2133) but he suggested it could of been my hard drive (seagate barracuda 1tb) because a few days before i purchased GTA V i played a bit of Overwatch and my models weren't working so he said it could have been my hard drive having issues loading the models so reinstalled the game and it worked. after 10-30 minutes of playing my game starts to get lag spikes like crazy, even in online especially while driving. sometimes it gets to the point it spikes so much the game crashes (this only happened in online so far)If anyone has a solution to this please let me know!
also temps dont go above 40c on my cpu

The simplest issue I can suggest is get a dedicated graphics card. GTA V is fairly demanding and using an integrated graphics isn't close to being enough. Consider picking up a 1050/RX 460 if you're on a budget.
