Although this won't work 100%, depending, the follow can fix most vertex errors. Under your games tab in steam, right click Gmod -> Properties -> Local files tab -> Verify integrity of game cache. Let it run, then rejoin. So far its been tested a few times and it seems to work for most errors. Go try it and tell me your results. Credits to Kaiden as well, who got a good reward
Try defragmenting the cache then, of the people i've told it works. Sometimes takes more than one attempt to work. Only defragmented once myself and i've yet to get it - ever
I have also tried that. HOpefully if you see viewtopic.php?f=48&t=7802 then you will realise that I have to reinstall Gmod anyway. Hopefully that will make a difference.
because your pc allocates and deallocates memory wrong over time and screws up. and installing and unintstalling move around a lot of memory, fragmenting your HDD
Well, I know for a FACT how HDD's works. And Yes Teddi, I always end up fucking up my HDD with Ubuntu. But Either way, It is being repaired as I speak, My Dad and I are working on it now. Hopefully There wont a problem in the future with Vertex Error's especially when the new update. HURRY UP and release it please. It will be sooooo cool.
Well I know that even using this method there is one spot on central17 that you always get a vertex error on. Maybe I should post screenshots.
