On all of my add on and replacement vehicles parts of my interior are kinda weird.  Check pictures.  Also on some of the regular civilian vehicles too but not all.  The dashboard this the biggest notice.  The side door panels.  Sides or all of the seats.  I even tried to reinstall one of the vehicles and it didn't fix it.  Everything it up to date.  Same thing when normal GTAV is launched.  So could it be a game file?  I haven't installed anything else lately.  I noticed once in a while a civilian vehicle would disappear in the distance.  A couple other very minor glitches.  I noticed those after the 5 or 6 add on vehicle I put in.  Yup,  I have the latest game config.  So I'm not sure what else to try.  My video card is up to date.  What do you all think?

Hey.  So, it looks like loss of frames and texture.  What are your graphics settings set too?

 

Also, the models you've downloaded and installed... Have you checked the page you downloaded the files from to see if the example pictures have the same texture loss?  Just a thought,

 

Although, you've claimed it is also happening with civilian vehicles (AI)?
