All of the Pub demo's are very laggy. you can't see whats going on through majority of the demo's. I have download several random demos from the pub ftp and they're all just lagging all over the place.
valve randomly added a command to break demo playback by making it work like cs go. As a result demos are recorded at 16 tick rate b/c that is the obvious tick rate a cs:go player would want to have things recorded at. This setting was then applied to cs:s with no documentation or notice.
I have made it 66 on cs:s and 128 on go so that it will be the exact same as the server tick rates.
Ok so I was trying to watch a demo today but it would go real fast through about 2k ticks and then d/c me. Tried gg and zm demos and they work fine. Seem to only have probs with Pub demos?
