I don't know if it's just me but big packets has been dropping my FPS a ton especially when it's enabled. Any other game I play I get 150+ FPS.
FPS drops are usually the result of unoptimized code in hacks (which I don't blame bigpackets for, it even happened to Windows) or the game simply not being able to handle what it renders but I don't blame bigpackets for it, the Gmod hack is for a 32 bit game with virtually no multicore rendering support
To improve fps I usually only turn on enemy ESP (which is fine for what I play; zombie survival) and turn off everything else
As for the crashing it seems like it only happens upon starting Garry's Mod or after it has been running for a while which seems normal for even GTA mod menus in my experience
