[Tutorial] Static Car Models

[Tekk]

im still wondering how too much traffic in races causes lag when they kinda standing by doing nothing except shaking a little

Old games were CPU-dependant and GTA SA is no exception. Not to mention it was originally made for the singlecore CPUs so it never got any optimizations for the newer systems later. I can't say much regarding MTA or NFS:SA in particular, but I had pretty shitty experience when I was running the game on my 2014 model year laptop. So yeah, the amount of additional traffic and props may drastically affect performance if there's too much stuff on the screen, even if it's something low poly. Hope that this answers your question.
