Framedrops in Gmod 13

When Gmod12 updated to Gmod 13, I suddenly getting more framedrops then before
There is nothing in the startup command line on Steam so I don’t know what the problem is
Can anyone please help me with this…

It’s a GMod Bug, it’s happened with me in GMod 12.

It’s worst with SCars, it was completely normal in GMod 12 but in GMod 13 with Checkpoints, AI and like 3 cars (including mine), it drops down to like 3 fps. Garry really needs to sort this out, I was tempted to post a topic about this one too since it happened before this August.

Hmm, I’d like it to that this needs to be fixed because now Gmod isn’t so nice if it has framedrops…
