I tried enabling vsync but it doesn't help, also my video drivers are up to date (using AMD). I used the updater and there were 3 files missing but they appeared to be missions, not sure why it would need to download them but still no weapon models.
As for messages in the console i see nothing that could refer to weapon models, only some warnings about some sounds that can't be loaded
Edit: oh my god nevermind, just found out that keeping the console open for a few seconds fixes the problem
