No problem 🙂 yeah just keep making back-ups so if anything goes wrong and you have to install stuff again, you don't have to spend a long time on it.

most likely be something you added that's causing your game to lag as some mods can be intensive.
 
however if you didn't add anything prior to this happening it could be some of the mods updating possibly, go into your task manager and see how much usage the gtav is taking up.

I did as you suggested and looked through everything nothing has been updated before the first time I had the lag I removed my mods folder from OpenIV and it seems to have done the trick I must have screwed up in there somewhere. Kind of frustrating Ill have to reinstall everything in there so I put that off until the very last. Thanks for your help!
