[quote=Merchant]This is why I try not to touch my setting, it hurts my head.

Basically what I am hearing is 0.033 in hitscan classes configs and cl_interp_ratio 2 and in projectile classes 0.0152 and cl_interp_ratio 1.

Hitscan:
Scout, Sniper, Spy?, Heavy, Engineer

Projectile:
Demo, Soldier, Pyro?

What about medic? Projectile cause needles?[/quote]
According to [url=http://teamfortress.tv/forum/thread/11394-interp-lerp-other-stuff#post-8]this post[/url], which is one of the ones I based my posts on, cl_interp should always remain 0, and cl_interp_ratio 1 actually = 0.0152 while cl_interp_ratio 2 actually = 0.0303 , so you are just changing the interp_ratio

Some further research lead me to [url=http://www.reddit.com/r/tf2/comments/1fdi64/a_small_guide_on_cl_interp_and_how_it_influences/ca9j6oi]this post on reddit[/url] by ond_kaja where he explains why you should only mess with interp_ration and not interp itself.

So I don't know, I'm just basing what I had on some of these posts.

I've used a bunch of different interp settings over the years. For me, I get the best hit detection for both hitscan and projectiles with a cl_interp of 0 and a cl_interp_ratio of 1.
