did you forget the "and 0.0152 (for projectiles)" or are you saying you just switch between them a lot like people change crosshairs/sens?

If the latter: You'll be fine. I do it sometimes as well and barely ever notice a difference
if the former: if you use cl_interp in your class cfgs nothing will happen because you can only change interps when you're in spec or on the main menu. It'll make your settings a mess because sometimes you'd be using 0.033 for projectiles or 0.0152 for hitscan depending on which classes you played first. If you do this then I suggest just picking one and sticking with it. But only because it's not how the command functions and just makes your settings a mess

also in general the whole 0.0152 vs 0.033 thing has always seemed pretty placebo to me. There's a difference ofcourse but it's so tiny it's negligable

edit: I was wrong. Apparently you can change interps by switching classes. You'll be fine

The interp does change when you switch class

You can't change interp or any net setting once connected to a server.

but it does switch interp if you have different ones in class cfgs, even in a server

Interesting. didn't know that. thanks for the correction :)

sniped

does anyone else hear a hit noise with a soldier melee but it doesnt damage them
this tilts me to new undiscovered anger levels

ya i meant 0.0152 for projectile sorry

happens with any class

yeah it makes a noise but for some reason the actual hit is calculated slightly later

no, it doesn’t create inconsistencies afaik

It's fine but you might want to use cl_interp 0 and cl_interp_ratio 1 or 2 (1 for projectile and 2 for hitscan) as those are way more precise values than just unsing the interp command.
Quoting Mastercom in the lastest version of her graphical config:

cl_interp 0 // Use cl_interp_ratio for a more accurate value
cl_interp_ratio 1 // Reduce entity interpolation times to minimum
//cl_interp_ratio 2 // Fix lag when experiencing packet loss, 3 or 4 for lots of packet loss

tbh if you can use 15.2ms lerp for projectile then just use the same for everything
I used to go between the two for a while and then eventually realised it's mostly placebo anyway. 15.2ms shows projectiles the fastest so just use it (unless you have a bad connection of course)
