i was just on a server and it works fine, did you make sure the server you are on doesn't restrict interp or it's not in your config?

check your cl_interp_ratio

i checked multiple servers

it was set to 2, what should i change it to?

Ideally you fiddle with it until your interp is 15.2 ms but having it at 100 ms seems like something else is screwed up

are you running chris' configs? make sure you're on the good net setting and not the bad one, I regularly end up with 50+ ms interp when I use the bad connection settings

no, im using stock tf2 settings. i just reinstalled tf2

I got 99 problem and interp is all of them.

Anyway, interp is reliant on your other rate settings (cl_cmdrate, cl_updaterate). I find that for some reason, despite not having any change to these rates in any of my cfgs, these values will be changed on their own. Depending on what they are changed to, they will not allow interp to go below certain values.

So set both cl_cmdrate and cl_updaterate to a value of 66. This should fix your problem or I aint blood rawdog sire.

edit: further explanation, usually these rates are halved for me, defaulting my interp to .05 ...I use cl_interp_ratio 1, cl_interp_ratio 2 (as you are using) is likely taking the same issue and raising the .05 to .100ms

your interp is whichever is higher between (interp_ratio*1/updaterate) and (interp)
so if changing cl_interp isn't working, check cl_updaterate, try setting it to 66 and cl_interp_ratio to 1

EDIT: ninja'd

that fix it. thanks :)

now i can blame myself for being bad

glad it helped, make sure you have a key bound to net_graph 3 so you can sporadically check what your interp is, and make sure your other rate values weren't altered. Many times I'll join up and feel like my rockets are swimming in water, then I check the graph and see that my interp is funky due to the rates being changed

also, pray to the rate gods

yeah, i got a key bind to that ^^
